SMALL

1.0
SCOPE
AND
APPLICATION
1.1
Method
1020
makes
uses
the
small
scale
closed­
cup
apparatus
(
formerly
the
Setaflash
closed
tester)
to
determine
the
flash
point
of
liquids
that
have
flash
points
between
0
°
and
110
°
C
(
32
and
230
°
F)
and
viscosities
lower
than
150
stokes
at
25
°
C
(
77
°
F).

1.2
The
procedure
may
be
used
to
determine
whether
a
material
will
or
will
not
flash
at
a
specified
temperature
or
to
determine
the
finite
temperature
at
which
a
material
will
flash.

1.3
This
method
is
one
of
two
method
options
required
in
40
CFR
261.21(
a)(
1)
for
the
determination
of
the
hazardous
waste
ignitability
characteristic.
Method
1010
(
Pensky­
Martens
Closed­
Cup
Method
for
Determining
Ignitability)
is
the
other
method
option.
Liquids
that
tend
to
form
surface
films
under
test
conditions
or
those
that
contain
non­
filterable
suspended
solids
should
be
tested
for
the
hazardous
waste
ignitability
characteristic
using
Method
1010.

2.0
SUMMARY
OF
METHOD
2.1
By
means
of
a
syringe,
2­
mL
of
sample
is
introduced
through
a
leak­
proof
entry
port
into
the
tightly
closed
small
scale
tester
or
directly
into
the
cup
which
has
been
brought
to
within
3
°
C
(
5
°
F)
below
the
expected
flash
point.

2.2
As
a
flash/
no­
flash
test,
the
expected
flash­
point
temperature
may
be
a
specification
(
e.
g.,
60
°
C).
For
specification
testing,
the
temperature
of
the
apparatus
is
raised
to
the
precise
temperature
of
the
specification
flash
point
by
slight
adjustment
of
the
temperature
dial.
After
1
minute,
a
test
flame
is
applied
inside
the
cup
and
note
is
taken
as
to
whether
the
test
sample
flashes
or
not.
If
a
repeat
test
is
necessary,
a
fresh
sample
should
be
used.

2.3
For
a
finite
flash
management,
the
temperature
is
sequentially
increased
through
the
anticipated
range,
the
test
flame
being
applied
at
5
°
C
(
9
°
F)
intervals
until
a
flash
is
observed.
A
repeat
determination
is
then
made
using
a
fresh
sample,
starting
the
test
at
the
temperature
of
the
last
interval
before
the
flash
point
of
the
material
and
making
tests
at
increasing
0.5
°
C
(
1
°
F)
intervals.

complete
instructions

ignitability
test
