This part of IEC 62321 provides strategies of sampling along with the mechanical preparation of samples
from electrotechnical products, electronic assemblies and electronic components. These
samples can be used for analytical testing to determine the levels of certain substances as described in the test methods in other parts of IEC 62321. Restrictions for substances will vary between geographic regions and from time to
time. This Standard describes a generic process for obtaining and preparing samples
prior to the determination of any substance which are under concern.
This standard does not provide:
— full guidance on each and every product that could be classified as electrotechnical
equipment. Since there is a huge variety of electrotechnical components, with various
structures and processes, along with the continuous innovations in the industry, it
is unrealistic to attempt to provide procedures for the disjointment of every type
of component;
— guidance regarding other routes to gather additional information on certain substances in a product, although the information collected has relevance to the sampling strategies
in this standard;
— safe disassembly and mechanical disjointment instructions related to electrotechnical
products (e.g. mercury-containing switches) and the recycling industry (e.g. how to
...
