Significance and Use Sampling of decorated glass containers for
the TCLP can vary greatly, resulting from the size and shape of
the article relative to the amount of ceramic decoration on the
ware. Breaking the glass can cause some of the pieces to have no
decoration on them, and others to be heavily decorated and more
likely to leach lead and cadmium under the TCLP test. This
method provides an effective tool to homogenize the glass
containers so that reproducible results can be attained from the
TCLP test. 1.1 This test method defines the way in which
container glassware should be prepared before performing the
Toxicity Characteristic Leaching Procedure (TCLP). The method
covers the homogenization of the sample, and the selection of a
representative portion of the sample to test and get
reproducible results. 1.2 The values stated in SI units are to
be regarded as standard. No other units of measurement are
included in this standard. 1.3 This standard does not purport to
address all of the safety concerns, i
