Among the guidelines on the use of certain
hazardous substances, RoHS Directive has become
the most representative dealing in environmental
regulations. The main points discussed in RoHS
Directive are Homogenous Material (HM) and
Maximum Concentration Value (MCV). It involves that
HM as a sample in the test for analyzing hazardous
substance should have identical composition, and it
should be minimum substance which cannot be
separated by mechanical separation including
unscrewing, cutting, grinding, abrasive process and
others (Wager et al., 2009).
