CHAPTER
EIGHT
METHODS
FOR
DETERMINING
CHARACTERISTICS
This
chapter
addresses
procedures
for
method­
defined
parameters,
where
the
analytical
result
is
wholly
dependant
on
the
process
used
to
make
the
measurement.
Examples
include
the
use
of
the
toxicity
characteristic
leaching
procedure
(
TCLP)
to
prepare
a
leachate,
and
the
flash
point,
pH,
paint
filter
liquids,
and
corrosivity
tests.
In
these
instances,
changes
to
the
specific
methods
may
change
the
end
result
and
incorrectly
identify
a
waste
as
nonhazardous.
Therefore,
when
the
measurement
of
such
method­
defined
parameters
is
required
by
regulation,
those
methods
are
not
subject
to
the
flexibility
afforded
in
other
SW­
846
methods
(
such
as
described
in
the
Disclaimer
and
Chapter
Two
of
this
manual).

Methods
for
determining
the
characteristics
of
ignitability
for
liquids,
corrosivity
for
liquids,
and
toxicity
are
included.
