1.0
SCOPE
AND
APPLICATION
1.1
This
method
is
used
to
determine
the
presence
of
free
liquids
in
a
representative
sample
of
waste.

1.2
The
method
is
used
to
determine
compliance
with
40
CFR
264.314
and
265.314.

2.0
SUMMARY
OF
METHOD
2.1
A
predetermined
amount
of
material
is
placed
in
a
paint
filter.
If
any
portion
of
the
material
passes
through
and
drops
from
the
filter
within
the
5­
min
test
period,
the
material
is
deemed
to
contain
free
liquids.

3.0
INTERFERENCES
3.1
Filter
media
were
observed
to
separate
from
the
filter
cone
on
exposure
to
alkaline
materials.
This
development
causes
no
problem
if
the
sample
is
not
disturbed.

3.2
Temperature
can
affect
the
test
results
if
the
test
is
performed
below
the
freezing
point
of
any
liquid
in
the
sample.
Tests
must
be
performed
above
the
freezing
point
and
can,
but
are
not
required
to,
exceed
room
temperature
of
25
oC.

4.0
APPARATUS
AND
MATERIALS
4.1
Conical
paint
filter:
Mesh
number
60
+/­
5%
(
fine
meshed
size).
Available
at
local
paint
stores
such
as
Sherwin­
Williams
and
Glidden.

4.2
Glass
funnel:
If
the
paint
filter,
with
the
waste,
cannot
sustain
its
weight
on
the
ring
stand,
then
a
fluted
glass
funnel
or
glass
funnel
with
a
mouth
large
enough
to
allow
at
least
1
in.
of
the
filter
mesh
to
protrude
should
be
used
to
support
the
filter.
The
funnel
should
be
fluted
or
have
a
large
open
mouth
in
order
to
support
the
paint
filter
yet
not
interfere
with
the
movement,
to
the
graduated
cylinder,
of
the
liquid
that
passes
through
the
filter
mesh.

4.3
Ring
stand
and
ring,
or
tripod.

4.4
Graduated
cylinder
or
beaker:
100­
mL.

SAMPLE
COLLECTION,
PRESERVATION,
AND
HANDLING
A
100­
mL
or
100­
g
representative
sample
is
required
for
the
test.
If
it
is
not
possible
to
obtain
a
sample
of
100
mL
or
100
g
that
is
sufficiently
representative
of
the
waste,
the
analyst
may
use
larger
size
samples
in
multiples
of
100
mL
or
100
g,
i.
e.,
200,
300,
400
mL
or
g.
However,
when
larger
samples
are
used,
analysts
shall
divide
the
sample
into
100­
mL
or
100­
g
portions
and
test
each
portion
separately.
If
any
portion
contains
free
liquids,
the
entire
sample
is
considered
to
have
free
liquids.
If
the
sample
is
measured
volumetrically,
then
it
should
lack
major
air
spaces
or
voids.

7.0
PROCEDURE
7.1
Assemble
test
apparatus
as
shown
in
Figure
1.

7.2
Place
sample
in
the
filter.
A
funnel
may
be
used
to
provide
support
for
the
paint
filter.
If
the
sample
is
of
such
light
bulk
density
that
it
overflow
the
filter,
then
the
sides
of
the
filter
can
be
extended
upward
by
taping
filter
paper
to
the
inside
of
the
filter
and
above
the
mesh.
Settling
the
sample
into
the
paint
filter
may
be
facilitated
by
lightly
tapping
the
side
of
the
filter
as
it
is
being
filled.

7.3
In
order
to
assure
uniformity
and
standardization
of
the
test,
material
such
as
sorbent
pads
or
pillows
which
do
not
conform
to
the
shape
of
the
paint
filter,
should
be
cut
into
small
pieces
and
poured
into
the
filter.
Sample
size
reduction
may
be
accomplished
by
cutting
the
sorbent
material
with
scissors,
shears,
knife,
or
other
such
device
so
as
to
preserve
as
much
of
the
original
integrity
of
the
sorbent
fabric
as
possible.
Sorbents
enclosed
in
a
fabric
should
be
mixed
with
the
resultant
fabric
pieces.
The
particles
to
be
tested
should
be
reduced
smaller
than
1
cm
(
i.
e.,
should
be
capable
of
passing
through
a
9.5
mm
(
0.375
inch)
standard
sieve).
Grinding
sorbent
materials
should
be
avoided
as
this
may
destroy
the
integrity
of
the
sorbent
and
produce
many
"
fine
particles"
which
would
normally
not
be
present.

7.4
For
brittle
materials
larger
than
1
cm
that
do
not
conform
to
the
filter,
light
crushing
to
reduce
oversize
particles
is
acceptable
if
it
is
not
practical
to
cut
the
material.
Materials
such
as
clay,
silica
gel,
and
some
polymers
may
fall
into
this
category.

7.5
Allow
sample
to
drain
for
5
min
into
the
graduated
cylinder.

7.6
If
any
portion
of
the
test
material
collects
in
the
graduated
cylinder
in
the
5­
min
period,
then
the
material
is
deemed
to
contain
free
liquids
for
purposes
of
40
CFR
264.314
and
265.314.
