1.0
SCOPE
AND
APPLICATION
1.1
Method
1010
uses
the
Pensky­
Martens
closed­
cup
tester
to
determine
the
flash
point
of
liquids
including
those
that
tend
to
form
a
surface
film
under
test
conditions.
Liquids
containing
non­
filterable,
suspended
solids
can
also
be
tested
using
this
method.

1.2
This
method
is
one
of
two
method
options
required
by
40
CFR
261.21(
a)(
1)
in
the
determination
of
the
hazardous
waste
ignitability
characteristic.
Method
1020
is
the
other
method
option.

2.0
SUMMARY
OF
METHOD
2.1
The
sample
is
heated
at
a
slow,
constant
rate
with
continual
stirring.
A
small
flame
is
directed
into
the
cup
at
regular
intervals
with
simultaneous
interruption
of
stirring.
The
flash
point
is
the
lowest
temperature
at
which
application
of
the
test
flame
ignites
the
vapor
above
the
sample.

how
to
conduct
a
test
