material), the waste, after filtration through a 0.6 to 0.8 µm glass fiber

material), the waste, after filtration through a 0.6 to 0.8 µm glass fiber
filter, is defined as the TCLP extract.
2.2 For wastes containing greater than or equal to 0.5% solids, the
liquid, if any, is separated from the solid phase and stored for later analysis;
the particle size of the solid phase is reduced, if necessary. The solid phase
is extracted with an amount of extraction fluid equal to 20 times the weight of
the solid phase. The extraction fluid employed is a function of the alkalinity
of the solid phase of the waste. A special extractor vessel is used when testing
for volatile analytes (see Table 1 for a list of volatile compounds). Following
extraction, the liquid extract is separated from the solid phase by filtration
through a 0.6 to 0.8 µm glass fiber filter.
2.3 If compatible (i.e., multiple phases will not form on combination),
the initial liquid phase of the waste is added to the liquid extract, and these
are analyzed together. If incompatible, the liquids are analyzed separately and
the results are mathematically combined to yield a volume-weighted average详细>
