6 Selection, Use and Maintenance of Protectors

Removed.

6.1 Protectors

Protectors are personal protective devices designed to protect the
wearer from potential hazards that could adversely affect a person's
eyes and/or face. Depending on the potential hazard, the protector may
be designed to block flying objects or hazardous liquids, filter optical
radiation, or enhance the wearer's vision for performing certain visual
tasks. It is also important to realize that different categories are
tested at different levels of impact resistance. There are three
categories of protector lenses based on transmittance: clear, filter and
special purpose (tables 1 and 2). There are many types of protectors
available. In the following sections, llustrations of various types of
devices used to protect the eyes and face are provided for guidance
only; they are not intended to show every type of device available.

Removed. Covered by “3. Definitions.”

6.1.1 Spectacles and Spectacle

Components

Spectacles are protective devices designed to shield the wearer's eyes
from various impact, or impact and optical radiation hazards. A
spectacle commonly consists of the following components: a front, a lens
or lenses, a pair of temples, and side protection (figure 1). Spectacle
components can be assembled in various combinations to make a complete
protector to provide the user with a wide selection of suitable
equipment for differing

applications.

Removed. Covered by “3. Definitions.”

6.1.1.1 Temples

A temple (figure 2) is that component of a spectacle that extends from
the front to just behind the wearer's ear or continues completely around
the wearer's head and is used to secure the frame in its proper use
position. Temples are usually hinged at the front to permit easy storage
when not in use and they are commonly available in the following three
types: (1) spatula temples, (2) cable temples, and (3) headband temples.
To properly fit the wide variety of wearers, temples are adjustable
and/or available in various lengths.

Removed. Covered by “3. Definitions.”

6.1.1.2 Fronts

The front (figure 3) is that component of a spectacle that retains the
lens or lenses in the proper orientation for viewing. The front can be a
separate part from the lens (removable lens type) or can be molded as an
integral part of the lens (non-removable lens type). Frames for

prescription lenses usually incorporate the removable type lens front.
Cover spectacles are typically the non-removable lens type.

Removed. Covered by “3. Definitions.”

6.1.1.3 Lenses

Lenses are that component of a spectacle through which the wearer sees
and which provides a protective barrier. Lenses are available in various
materials, shapes, thicknesses, shades and tints depending on their
particular application. Lenses also can be made to refract or bend light
to magnify an object or provide corrective vision to a wearer's
individual prescription (Rx). Lenses that do not refract light are
considered "plano" and do not provide corrected vision.

6.1.1.4 Bridges/Nose Piece

A bridge or nose piece (figure 4) is that component of a spectacle,
which supports the front on a wearer's face and typically rests on the
bridge of the wearer's nose. Bridges are commonly available in three
types: (1) fixed bridge (non-adjustable), (2) universal/saddle, and (3)
adjustable nose pad. Bridge sizes are expressed in millimeters and
measured as the distance between lenses (DBL).

6.1.1.5 Side Protection

Side protection (Figure 5) is that component of a spectacle that extends
from the front to some distance between the front and the wearer's ear
and provides limited protection to the wearer's eyes from lateral
hazards. Side protection may be an integral part of the frame or lens, a
separate side shield that is permanently attached to the frame, or a
removable part of the frame. The function and coverage of side
protection are defined by the high velocity impact test (section 14.2).

6.1.1.6 Special Purpose Spectacles

Special purpose spectacles are those which use lenses designed for a
specific application. Examples of products for such applications
include, but are not limited to, sunglasses, notch filters (e.g. –
didymium containing), and furnace glasses. Special purpose spectacles
use lenses that meet the requirements of table (2).

Removed. Covered by “3. Definitions.”

6.1.1.7 Lift-Front Spectacles

A lift-front spectacle (figure 6) is a spectacle conforming to the
requirements of this standard

that has an additional permanent or removable front attached, that can
be raised or lowered to the wearer's line of sight. The lift-front
component is typically used to provide additional protection, as needed,
from glare, optical radiation, or both, or is used for special viewing
tasks, such as magnification, and is marked accordingly. Lift-front
spectacles are evaluated for impact and optical performance with the
lift-front in the up position. The liftfront lens is evaluated for
optical perfonnance requirements of 7.4 or 7.5.

Removed. Covered by “3. Definitions.”

6.1.2 Goggles and Goggle Components

Goggles are protective devices designed to fit snugly but not
necessarily seal completely to a wearer's face surrounding the wearer's
eyes in order to shield the eyes. Goggles provide more protection than
spectacles from impact, dust, liquid splash and optical radiation
hazards. A goggle commonly consists of the following components: a
frame, a lens or lenses, ventilation area and headband. Goggles (figure
7) are commonly available in two styles: (1) eyecup goggles that cover
the eye sockets completely; and (2) cover goggles, which may be worn
over spectacles. Goggles are commonly available with rigid or flexible
frames and are usually ventilated to minimize

fogging. Three different types of ventilation are available: (1) direct
ventilation, (2) indirect ventilation, and (3) goggles with no
ventilation provision. Direct ventilated goggles pennit the direct
passage of air from the work environment into the goggle and are not
recommended for use in protection against liquid splash hazards.
Indirect ventilated goggles pennit the passage of air and may prevent
the direct passage of liquids and/or optical radiation. Goggles with no
provision for ventilation minimize passage of dusts, mist, liquid splash
and vapor. Goggles are available in many configurations to provide the
user with a wide selection of suitable equipment.

6.1.2.1 Side Protection

Side protection is that component of a goggle that extends from the
front to some distance between the front and the wearer's ear and
provides limited protection to the wearer's eyes from lateral hazards.
Side protection in goggles is commonly an integral part of the frame or
lens. The function and coverage of side protection are defined by the
high velocity impact test (section 14.2).

6.1.2.2 Lift Front

A lift-front goggle is a goggle confonning to the requirements of this
standard that has an additional pennanent or removable front attached,
that can be raised or lowered to the wearer's line of sight. The
lift-front-component is typically used to provide additional protection,
as needed, from glare, optical radiation, or both, or is used for
special viewing tasks, such as magnification, and is marked

accordingly. Lift-front goggles are evaluated for impact and optical
performance with the liftfront in the up position. The lift front lens
is evaluated for optical performance requirements

of 8.4 or 8.5.

meet the requirements of table 2.

Removed. Covered by “3. Definitions.”

6.1.3 Faceshields and Faceshield Components

Faceshields are protective devices designed to shield the wearer's face,
or portions thereof, in addition to the eyes, from various hazards.
Faceshields shall be used only in conjunction with spectacles and/or
goggles and provide a higher level of protection than spectacles or
goggles alone. Faceshields are used to provide protection from impact,
dust, liquid splash and optical radiation hazards. Faceshields (figure
8) may be used with a headgear assembly designed to suspend a
transparent window that surrounds and shields the wearer's face.
Faceshields may be incorporated with head protection. Faceshields also
may provide neck and chin protectors. The assembled devices are
available in many combinations of the various component types to provide
the user with a wide choice of suitable equipment.

Removed. Covered by “3. Definitions.”

6.1.3.1 Faceshield Windows

Faceshield windows provide a protective barrier between the work
environment and the wearer's eyes and face. Faceshields are available in

various materials, shapes, thickness, shades and tints depending on
their particular application. Commonly available windows are plastic,
plastic with a glass insert, or a wire screen.

Removed. Covered by “3. Definitions.”

6.1.3.2 Special Purpose Faceshields

Special purpose faceshields are those which use windows designed for a
specific application. Special purpose faceshields may provide limited

protection from impact hazards, optical radiation, or both. Special
purpose faceshields meeting certain light transmittance requirements are
marked as "light", "medium", or "dark"

(section 9.4.5) or meet the requirements of table 2.

Removed. Covered by “3. Definitions.”

6.1.4 Welding Helmets and

Handshields

Welding helmets and handshields are protective devices designed to
provide protection to a wearer's eyes, face, ears, and front of the neck
against optical radiation and weld spatter. Welding helmets and
handshields shall be used

only in conjunction with spectacles, goggles, or both. There are three
types (figure 9) commonly available: (1) helmet with stationary lens,
(2) lift-front helmet; and (3) handshield. A welding helmet may be
mounted on a protective helmet with special accessories. A welding
helmet may be the respiratory inlet covering of a loose fitting
facepiece respirator.

Removed. Covered by “3. Definitions.”

6.1.4.1 Special Purpose Lenses and Windows

Special purpose lenses are designated as such because they do not meet
the transmittance requirements of table 1, but do meet the transmittance
requirements of table 2. A typical

example is a cobalt furnace lens.

Special purpose lenses and windows are further classified and marked in
accordance with the requirements of section 10.11. Only devices meeting
the applicable sections of this standard shall be used with special
purpose lenses. (For additional information, see ANSI Z49.1-1999.)

6.2 Hazard Assessment and Protector Selection	Annex J. Hazard Assessment
and Protector Selection	Moved to Annex.

6.2.1 General Requirements

Protectors shall be required where there is a reasonable probability of
an eye or face injury that could be minimized or prevented by the use of
such protection. In such cases,. employers and educational authorities
shall make eye and face protectors conveniently available to employees
and students for their use in the work environment, per applicable
federal and state regulations. The employees and students shall use such
devices. Where there is a reasonable probability of impact from flying
objects, a protector with side protection shall be required. Protectors
are not substitutes for engineering controls and sound safety practices.
Protectors alone should not be relied upon to provide the sole means of
protection against eye and face hazards. Protectors shall be used in
conjunction

with engineering controls and sound safety practices. Known hazards
should be removed or minimized to the extent possible. Employers and
employees should consult their federal, state and local safety and
health regulatory authorities to become knowledgeable of the legal
requirements applicable to their area. Under the Department of Labor,
the Federal Occupational Safety and Health Administration (Fed OSHA) has
codified in 29

Code of Federal Regulations (CFR) 1910 Occupational Safety and Health
Standards for General Industry, and 29 CFR 1926 Occupational Safety and
Health Standards for the Construction Industry specific legal
requirements and guidelines that employers must follow to protect their
employees adequately (see specifically 29 CFR 1910.133 and 29 CFR
1926.102). By law, state and local government authorities can implement
their own safety and health regulations if they are at least as
protective as the federal regulations.	Annex J.	Moved to Annex.

6.2.2 Hazard Assessment

It is necessary to consider certain general guidelines for assessing the
eye and face hazard situations that exist in the work environment and to
match the protective device to the particular hazard. The person
directly responsible for a safety program should apply common sense and
fundamental technical principles to accomplish

these tasks. This process is subjective by nature because of the
infinite variety of situations where face and eye protection may be
required. At a minimum, the following recommended

hazard assessment procedure should be followed in order to assess the
need for eye and face protective equipment.

(1) Survey the Work Area. Conduct a walk-through survey of the area. The
purpose of the survey is to identify sources of potential eye and face
hazards. Consideration should be given to the six hazard categories
addressed by this standard:

(a) Impact

(b) Heat

(c) Chemical (Liquid Splash)

(d) Dust

(e) Glare

(f) Optical Radiation

(2) Identify Sources of Hazards. During the walk-through survey observe:

(a) Sources of motion; i.e., machinery or processes where any movement
of tools, machine elements or particles could exist, or movement of
personnel that could result in collision with

stationary objects. 

(b) Sources of high temperatures that could result in facial bums, eye
injury or ignition of protective equipment, etc. 

(c) Types of chemical exposures.

(d) Sources of dust.

(e) Sources of optical radiation, i.e., welding, brazing, cutting,
furnaces, heat treating, high intensity light sources and

ultraviolet lamps.

(f) Layout of workplace and location of other personnel.

(g) Any electrical hazards.

(3) Organize Data. Following the walkthrough survey, organize the data
and information for use in the assessment of hazards. The objective is
to prepare for an analysis of the hazards in the environment to enable
proper selection of protective equipment.

(4) Analyze Data. Having gathered and organized data on a workplace,
make an estimate of the potential for eye and face injury. Each of the
basic hazards should be reviewed and a determination made as to the type
and level of each of the hazards found in the area. The possibility of
exposure to several hazards simultaneously should be considered.

(5) Selection. Specify the protector(s) suitable for the hazards
identified (see Selection Chart, Annex I - Attached at the end of the
standard).

(6) Reassessment of Hazards. A periodic reassessment of the work area
should be performed on a regular basis to identify changes in the hazard
situation that could affect the level of protection required. Reassess
the workplace hazard situation by identifying and evaluating new
equipment and processes, reviewing accident records, and reassessing the
suitability of previously selected eye and face protection.	Annex J.
Moved to Annex.

6.2.3 Protector Selection

After completing a thorough hazard assessment of the environment such as
recommended in section 6.2.2, the general procedure for selection of
protective equipment is as follows:

(I) Become familiar with the Selection Chart (Annex I - Attached at the
end of the standard), the types of protective equipment that are
available, their capabilities and limitations.

(2) Compare the hazards associated with the environment, i.e., impact
velocities, masses, projectile shape, radiation

intensities, etc., with the available protective equipment.

(3) Make a judgment in selection of the appropriate protective equipment
so that the protection is consistent with the reasonably probable
hazard.

(4) Basic impact protectors (lenses) may be used only in an environment
where the known or presumed hazards are of low velocity, low mass and
low impact nature. High impact protectors shall be used in an
environment when the known or presumed hazards are of a high velocity,
high mass or high impact nature.

(5) Provide and fit the user with the protective device and provide
instruction on its care, use and limitations as recommended in sections
6.2.4 and 6.2.6.

(Note: Be aware that spectacles, goggles, and face shields are tested
with different impact criteria so the protector selection should be
consistent to the testing.) The Selection Chart (Annex I - Attached at
the end of the standard) is intended to aid in identifying and selecting
the types of eye and face protectors that are available. The
capabilities and limitations for the hazard "source" operations are
listed in this guide. This guide is not intended to be the sole
reference in selecting the proper eye and face protector.	Annex J.	Moved
to Annex.

6.2.4 Product Use and Limitations

Protectors are a personal item. They should be issued for exclusive use
by a particular individual. However, in circumstances where protectors
are reissued, the protectors shall be maintained in a sanitary and
reliable condition as described in section 6.2.6. Employers and
educational authorities should train their employees and students in the
proper use, care, application, inspection, maintenance, storage, and
limitations of protective devices and provide them with all warnings,
cautions, instructions and limitations included with the protector by
the manufacturer. The wearer should follow all instructions provided by
the manufacturer. Caution shall be exercised to ensure that the level of
protection provided by any protector is adequate for its intended
purpose. See the Selection Chart (Annex I - Attached at the end of the
standard), for information on specific applications. For more
information regarding training please review the American National
Standard, Z490.1- 2001, "Criteria for Accepted Practices in Safety,
Health, and Environmental Training".	Annex J.	Moved to Annex.

6.2.4.1 Special Purpose Protectors and Lenses

Special purpose protectors and lenses are those which meet the
requirements of table 2, but do not meet the requirements of table 1.
They are designed for specific applications. They might not provide
adequate ultraviolet protection, infrared protection, or ultraviolet and
infrared protection when used for applications for which they are not
designed. Therefore, special purpose protectors and lenses shall be used
only after a complete hazard assessment and at the discretion of the
individual responsible for the selection of protectors.	Annex J.	Moved
to Annex.

6.2.4.2 Prescription (Rx) Eyewear

Wearers of prescription (Rx) eyewear shall wear eye protection that
incorporates the prescription

in its design or that can be worn over prescription lenses without
disrupting either the prescription eye wear or the protective eyewear.
Contact lens wearers should recognize that dusty and/or chemical
environments may represent an additional hazard. Contact lenses are not
protective devices. Wearers of contact lenses shall wear appropriate
protectors in

hazardous environments.	Annex J.	Moved to Annex.

6.2.4.3 Filter Lenses and Windows

A filter lens meets the ultraviolet, luminous and infrared transmittance
requirements of table I and is marked with a shade number that indicates
its transmittance levels in accordance

with table 1. Filter lenses of an appropriate shade are suitable for
protection from direct exposure to optical radiation from sources of

very high radiance, such as welding arcs. Filter lenses are also
suitable for protection from sources of low radiance, provided that they
are not so dark as to interfere with normal visual performance of the
task.	Annex J.	Moved to Annex.

6.2.4.4 Tinted Lenses and Windows

Lenses having low luminous transmittance should not be worn indoors,
except when needed for protection from optical radiation.

Care should be exercised in conjunction with wearing such lenses for
driving vehicles with tinted windshields or for night driving. Some
polarized lenses may present viewing problems

when reading liquid crystal displays. Some tinted lenses may absorb
certain wavelengths of visual displays or signs, rendering them
unreadable.	Annex J.	Moved to Annex.

6.2.4.5 Photochromic Lenses

Photochromic lenses darken when exposed to, and fade when removed from,
ultraviolet radiation or sunlight. They are frequently used to provide
comfortable vision for a wide range of ambient illumination. They should
be used with care where the wearer passes from outdoors to indoors in
the course of the job. Photochromic lenses that do not meet the
transmittance requirements of table 1 and the switching index
requirements of table 3 are not suitable for protection from direct
exposure to

high radiance sources (e.g., welding arcs and unshielded high intensity
lamps)" Photochromic lenses that do not meet the switching index
requirements in table 3 are not automatic darkening welding filters.
Photochromic lenses shall be used only after a complete hazard
assessment and at the discretion of the person responsible for the
selection of protectors, (See the Selection Chart, Annex I - Attached at
the end of the standard.)	Annex J.	Moved to Annex.

6.2.4.6 Protection from Low Radiance Sources of Ultraviolet and Visible
Radiation

Some lenses that comply with the transmittance requirements of table 2,
but not with all of the requirements of table 1, can provide sufficient
ultraviolet attenuation to be used for protection from direct exposure
to ultraviolet sources of low radiance and from indirect exposure (i.e.,
scattered radiation) to properly shielded ultraviolet sources of high
radiance. Lenses that have some attenuation of visible light may also be
suitable for protection from scattered light

from properly shielded high radiance sources of visible light, (See
Selection Chart, Annex I - Attached at the end of the standard.)	Annex
J.	Moved to Annex.

6.2.5 Fitting the Device

Careful consideration should be given to comfort and fit. Protectors
that fit poorly will not afford the protection for which they were
designed. Protectors should be fitted by qualified personnel. Continued
wearing of

protectors is more likely when they fit the wearer comfortably.
Protectors are generally available in a variety of styles and sizes and
care should be taken to ensure that the right size is selected for a
particular person. For devices with adjustable fitting features,
adjustments should be made on a regular and individual basis for a
comfortable fit, which will maintain the protective device in its proper
wearing position. Some protectors may not be compatible with other
personal protective equipment when worn together, such as goggles with
faceshields,

goggles with respirators and spectacles with goggles. The end user
should carefully match

protectors with other personal protective equipment to provide the
protection intended. Because of individual facial characteristics, care
must be exercised in fitting goggles to ensure that a snug fit around
the face is achieved in order to provide adequate protection.	Annex J.
Moved to Annex.

6.2.6 Inspection, Care and Maintenance

Wearers shall perform a visual inspection of their protectors prior to
each use. Protective devices that are distorted, broken or excessively
scratched or pitted are not suitable for use and shall be discarded.
Reasonable care shall be taken during the use and storage of protectors
so that they are not subject to unnecessary abuse. Protectors shall be
maintained in a usable condition in accordance with manufacturer's

instructions. When one protector is being used by more than one person,
it is recommended that

it be cleaned and disinfected prior to being used by a different
individual.	Annex J.	Moved to Annex.

case of short term exposure to light, the glare is approximately
proportional to

the product of the illuminance at the eye and time. The time dependence
of the darkening process can differ for different designs of filters
where the luminous transmittance varies with

time. It is therefore appropriate to define the response time of an
automatic darkening filter lens as an integral of the luminous
transmittance over time and not merely by the initial and final

luminous transmittance.

14 Test Methods

Unless otherwise specified, all tests shall be performed at normal
laboratory ambient conditions. In many tests the Alderson 50th
percentile male headform is specified; if, however, a product is
designed to fit a larger or smaller group of the population, then the
Alderson 95th percentile male or 5th percentile female headforms should
be used. Appropriate eye and face protection shall be worn for all
impact and penetration tests. Impact test methods are all type tests
except for drop ball tests for non-plano spectacle lenses

(section 14.4.2.1) (see 7.3.1). The frequency of repeating the type
tests should be in conformance to the manufacturer's quality assurance
protocol. Statistical sampling is an acceptable means of demonstrating
compliance with the performance criteria of sections 7 through 11. This
standard does not require the use of a specific sampling plan, however,
the plan chosen must be statistically significant. An example of an
acceptable plan is ANSI/AQC Z1.4-1993. Alternative test methods and
apparatus to those cited in this standard may be used if equivalent
results can be demonstrated. In case of dispute, the methods and
apparatus cited in this standard shall take precedence. 	9. Test Methods

Testing shall be performed on the number of complete devices specified
within the test sections below and summarized in Annex A. Unless
otherwise specified, all tests shall be performed at standard laboratory
conditions (23 ±5 °C, 50 % RH ±15%). In many tests, devices are
mounted on one of two headforms of the type defined by EN 168:2001,
Section 17 and referenced in Annex

B. When testing a protector, the appropriate sized headform (medium or
small) shall be used throughout the testing protocol. Alternative
measurement methods are acceptable

if shown to perform equivalently to the reference test methods cited in
this section.	Changed.

14.2.2 Apparatus

The test apparatus shall consist of an Alderson 50th percentile male
headform mounted vertically within an enclosure and a device capable of
propelling a 6.35 mm (0.25 in) steel ball weighing 1.06 g (0.037 oz)
reproducibly at velocities from 45.7 to 91.4 mls (150 to 300 ft/s) at
the headform. The path of the projectile shall be on a horizontal
reference plane formed by the center of the eyes of the headform. The
headform shall be capable of being rotated about the vertical axis
specified in 14.2.3 in 15° increments, from a first position 15° to
the nasal side of straight-ahead-viewing out to 90° temporally. The
headform shall be capable of being raised 10 mm (0.394 in) and lowered
10 mm (0.394 in) with respect to the horizontal reference plane to carry
out testing at the 90° angular position. Mass of the test headform
shall be at least 4 kg (8.8 lb). The velocity of the steel ball shall be
determined at a distance not greater than 25 cm (9.8 in) from the eye of
the headform and shall have a standard deviation not exceeding 2% of the
specified test velocity over a test series of 30 shots. Some form of
containment shall surround the headform to prevent debris or the
ricocheting projectile from endangering observers. Steel balls traveling
at high speeds can be lethal. Therefore, they shall be contained within
the test apparatus by appropriate engineering controls to prevent injury
or death. Information about a typical High Velocity Impact Test
Apparatus is given in annexes C and E.	9.12.2 Apparatus

The test apparatus shall consist of the headform mounted vertically
within an enclosure and a mechanism capable of propelling a 6.35 mm
(0.25 in.) diameter steel ball weighing 1.06 g (0.037 oz) reproducibly
at velocities from 45.7 to 91.4 m/s (I50 to 300 ft/s) at the headform.
Protectors marked with an "H" or intended for smaller anatomical
dimensions shall be tested on the smaller headform. The headform shall
be capable of being rotated about the vertical axis specified in Section
9.12.3 in 30° increments, from a first position which is directly
normal and centered to an eye of the headform to 90° temporally. The
headform shall be capable of being raised and lowered 10 mm (0.394 in)
for the headform, or 8 mm (0.315 in.)

for the smaller headform with respect to the horizontal reference plane
formed by the center of the eyes of the headform to carry out spatial
testing of frontal and temporal positions. Mass of the test headform
shall be at least 4 kg (8.8 lb.). The velocity of the steel ball shall
be determined at a distance not greater than 25 cm (9.8 in.) from

the eye of the headform and shall have a standard deviation not
exceeding 2% of the specified test velocity over a test series of 30
shots. Information about a typical High Velocity Impact Test Apparatus
is given in Annex E	Changed to include fewer impact sites.

14.2.3 Procedure

Apply a thin layer of white contact paste to each of the eyes of the
headform covering an area 25 mm (1.0 in) in diameter centered on the
corneal vertex of the eye. The protective device shall be mounted on the
headform in the manner in which the device was designed to be worn. The
headform shall be adjusted so that the path of the projectile passes
through the center of the anterior surface of either of the eyes of the
headform. The headform is then rotated on an axis, which passes
vertically at their intersection

of a sagittal plane through the center of the front surface of the
tested eye and a coronal (frontal) plane which is 10 mm posterior to the
corneal plane which is tangent to the anterior surfaces of the eyes of
the headform, to the first test position, which is 15° on the nasal
side. The device is impacted at the test velocity. The balls are damaged
during impact and should be changed frequently to avoid impacts at
unexpected locations and large variations in velocity. A new device is
then placed on the headform and impacted at 0°, another is impacted at
15° temporally, and so on, until eight devices have been impacted in
the horizontal plane of the center of the eyes of the headform, with
each impact centered on the axis of rotation which lies 10 mm posterior
to the center of the anterior surface of the test eye of the headform.
At the 90° angular position, one device shall be impacted 10 mm (0.394
in) above the plane of the eyes of the headform, and another device
shall be impacted 10 mm (0.394 in) below the plane of the eyes of the
headform. The total group size tested about one eye is ten devices with
one impact each at 15° nasal, 0°, 15°,30°,45°,60°,75° temporal,
and 3 impacts 90° temporal. A similar test is then carried out about
the other eye, resulting in a total of twenty devices tested.

14.2.4 Testing Spectacles Without Side Protection

When testing spectacles without side protection, one proceeds as in
14.2.3 until reaching the angle where the lens or front is no longer
impacted. Starting back at the 15° nasal position on the same side,
additional samples should be tested at 15° nasal, 0°, 15° temporal. A
similar procedure is then carried out on the other side of the headform.
9.12.3 Procedure

Testing shall be performed on the complete protector with its
non-removable lenses or representative test lenses. Apply a thin layer
of white contact paste to each of the eyes of the headform covering an
area 25 mm (1.0 in.) in diameter centered on the corneal vertex of the
eye. A new and complete device shall be mounted on the headform in the
manner in which the protector was designed to be worn. The headform
shall be adjusted so that the path of the projectile passes

through the center of the anterior surface of either of the eyes of the
headform. The headform is then

rotated on an axis which passes vertically at the intersection of a
sagittal plane through the center

of the front surface of the tested eye and a corneal (frontal) plane
which is 10 mm (0.394 in.) posterior to the corneal plane which is
tangent to the

anterior surfaces of the eyes of the headform, and/or raised or lowered
10 mm (0.394 in.) in height (or 8 mm for the smaller headform) to align
with each test position. A new complete device is impacted at the test
velocity as specified in Section 6.2.3. The balls are damaged during
impact and should be changed frequently to avoid impacts at unexpected
locations and large variations in velocity. Six impact sites shall be
tested for each type of

protector:

a. a point along the horizontal plane of the center of the eye of the
headform, and within a 10 mm (0.394 in.) diameter circle centered
directly in front of each eye of the headform. (Two total test sites)

b. within a 5 mm (0.197 in.) diameter circle centered on a point on the
horizontal plane of each eye at +30° (temporal). (Two total impact
sites).

c. within a 5 mm (0.197 in.) diameter circle centered on a point 10 mm
(0.394 in.) above the horizontal plane of the eye at +900 (temporal) to
one eye. If the frames are marked with an "H", the impact point shall be
within a 5 mm (0.197 in.) diameter circle centered 8 mm (0.315 in.)
above the horizontal plane of the eye +90° (temporal) to one eye. (One
total impact site)

d. within a 5 mm (0.197 in.) diameter circle centered on a point 10 mm
(0.394 in.) below the horizontal plane of the eye at +900 (temporal) to
the opposite eye of that used in c above. If the frames are marked with
an "H", the impact point shall be within a 5 mm (0.197 in.) diameter
circle centered 8

mm (0.315 in.) below the horizontal plane of the eye +90° (temporal) to
the opposite eye of that used in c above. (One total impact site).

A total of six complete devices shall be tested.	Changed to include
fewer impact sites.

shall be equipped with representative test lenses. The representative
test lenses shall be 2.0 mm +O.2mm -0.0 mm (0.079 in. +0.008 in. -0.0
in.) thick at their thinnest point.	New.

	9.12.3.2 For each prescription lens retention system, six complete
devices shall be tested for each lens retention system.	New.

	9.12.3.3 For prescription lens carriers, a new and complete device
shall be used for each impact point noted above for a + 5.00 D lens and
a new and complete device shall be used for each impact point noted
above for a - 5.00 D lens. A total of twelve (12) devices shall be
tested for prescription lens carrier frames, two devices impacted at
each site.	New.

14.2.5 Analysis of Results

Failure criteria are given in sections 7 through 11, excluding non-plano
high impact lenses, which are covered by Section 14.3, for the
particular type of device being tested. Examine the headform for pieces
of the protector adhering to the contact paste. Examine the device for
evidence of pieces missing from the inner surface of the device. Examine
the protector and the ball for any contact paste. Adherence of pieces to
the contact paste or contact paste on the ball or protector is evidence
of a failure. Examine the lens(es) closest to the eye for evidence of
fracture. If any fail, the device fails.

14.3 Test for High Impact Prescription Lenses

Plano power lenses, maximum base curve of 6.25, shall be edged round
with an industrial safety bevel to a diameter 55.0 mm +0.04 mm/- 0.25
mm. Each lens shall be tested once, with a new lens used for each
additional impact. Each lens shall be mounted in the test holder (see
figure B3) by two retaining washers so that the test lens is held firmly
against the bevel of the lens holder. Perfonn the high velocity impact

test on the center of each lens with the missile specified in 14.2 at a
velocity of 45.7 m/s (150 ft/sec.). Repeat the test with 2 additional
sample lenses, giving a total of three test lenses. Failure

consists of any posterior displacement of the lens completely through
the test holder; any fracture of the lens; any detachment of a portion
of the lens from its inner surface; or any full thickness penetration of
a lens. Failure of any lens constitutes a failure. If all test lenses
pass, then any prescription lens of the same or greater thickness at its
thinnest point, which is made by the same manufacturer, from the same
material,

with the same coatings and processes may bear the "+" mark.

Suitable supplies include ammonia gas cylinders, or bubbling air through
a wash bottle containing a concentrated

(~0.9g/ml water) solution of ammonia. The detection solution shall be
prepared by dissolving 5.0 ±0.5 g phenolphthalein in 500 ±50 ml
ethanol and adding 500 ±50 ml water, stirring constantly (filter if
precipitate forms) to obtain 1.0 ±O.I L of solution.	New.

	9.18.3 Procedure

Cover the headform with several layers of absorbent cotton lint. Dip the
white blotting paper into the detecting solution, shaking off any
excess.

Mount the moist paper over the lint, and then mount the protector on the
headform. Adjust the headband to a normal degree of tension. Adjust

the number of layers of lint, as necessary, to ensure a good seal
between the protector and the headform. Place a separate test strip of
blotting paper dipped in detection solution on the floor of the chamber.

Place the headform in the chamber. Open the chamber vent very slightly,
then slowly introduce ammonia gas to fill the chamber. When the test
strip changes to a crimson color, close the vent and leave the headform
in the closed chamber for 5.0 ±0.2 min. At the end of this time,
evacuate the chamber thoroughly by operating the blower. After the
chamber has cleared of ammonia, remove the headform. Examine the test

refocused on the radial lines until they appear as sharp as possible.
Two possibilities may then occur, all or just some of the lines will
appear well focused. If all radial lines appear equally well-focused at
the same position of the focus wheel, the lens has no measurable
astigmatism and the power reading of the telescope is the refractive
power of the test lens. If lines in only one meridian appear sharpest at
a given focus, then the telescope shall be refocused to determine the
best focus for the lines in the meridian which yield an extreme (maximum

yields the opposite extreme power reading. The second power reading
shall be noted. The astigmatism shall be calculated as the absolute
value of the algebraic difference between the two extreme power
readings.

tested. The distance between the lens being tested and the objective
lens of the telescope shall not exceed 38 mm (1.5 in.). The telescope is
then refocused on the radial lines until they appear as sharp as
possible. Two possibilities may then occur, all or just some of the
lines will appear well focused. If all radial lines appear equally
well-focused at the same position of the focus wheel, the lens has no
measurable astigmatism and the power reading of the telescope is the
refractive power of the test lens.

If lines in only one meridian appear sharpest at a given focus, then the
telescope shall be refocused to determine the best focus for the lines

in the meridian which yield an extreme (maximum or minimum) power
reading. The power reading shall be noted. The telescope shall be then
re-focused for lines in the meridian which yields the opposite extreme
power reading. The second power reading shall be noted. The astigmatism
shall be calculated as the absolute value of the algebraic difference
between the two extreme power readings. The telescope shall then be
re-focused for the best compromise focus, that is, until all radial
lines appear equally sharp. The sunburst test pattern shall be replaced

14.13.3 Procedure

The test specimen (automatic darkening welding filter) shall be
maintained at the appropriate test temperature for a minimum of 2 hours
before testing and during the period of test. Ambient lighting
conditions during testing shall not exceed 16 lux. The test specimen and
light detectors shall be mounted normal to the beam of illumination.

Solar or photoelectric power cells shall be shielded from the
transmittance light source beam. Methods shall be employed to ensure
that the temperature of the lens under test does not exceed the
prescribed test temperature (For

example: due to exposure from the transmittance light source). With the
transmittance light source activated,

the trigger light source shall be switched to its high illumination
state. The luminance variations over time, of the triggering light
source at the filter and the transmittance light source through the
filter, shall be recorded.	9.15.3 Procedure

The automatic darkening welding filter shall be maintained at the
appropriate test temperature for a minimum of 2 hours before testing and
during the period of test. Ambient lighting conditions during testing
shall not exceed 16 lux. All but anyone sensor of the automatic
darkening welding filter shall be occluded with opaque material. The
automatic darkening welding filter and light detectors shall be mounted
normal to the beam of illumination. Solar or photoelectric power cells
shall be shielded from the transmittance light source beam.

Methods shall be employed to ensure that the temperature of the lens
under test does not exceed the prescribed test temperature (For example:
due to exposure from the transmittance light source). With the
transmittance light source activated, the trigger light source shall be
switched to its high illumination state. The luminance variations over
time, both of the triggering light source at the filter and the
transmittance light source through the filter, shall be recorded. The
switching index shall be calculated using the equation given in Section
3, and setting t== 0 as the time when the recorded trigger source
illuminance reached 5000 lux. Repeat test as necessary until all sensors
on the device have been tested individually (with others occluded). One
complete device shall be tested.	Same.

14.13.4 Analysis of Results

The switching index shall be calculated from the integral given in
section 12.1 equation 7, taking t=O as the time when recorded
illuminance reaches 5000 lux. Failure criteria are given in section
10.12.4 and 10.12.5.
