IEC 62321-2-2021 pdf free download – Determination of certain substances in electrotechnical products – Part 2: Disassembly, disjointment and mechanical sample preparation.
1 scope
This part of lEC 62321 provides strategies of sampling along with the mechanical preparationof samples from electrotechnical products.These samples can be used for analytical testing todetermine the levels of certain substances as described in the test methods in other parts ofthe lEC 62321 series.Restrictions for substances will vary between geographic regions andcan be updated on a regular basis. This document describes a generic process for obtainingand preparing samples prior to the determination of any substance of concern.
This document does not provide:
– full guidance on each and every product that could be classified as electrotechnical product.
Since there is a huge variety of electrotechnical parts，with various structures andcompositions,along with the continuous innovations in the industry, it is unrealistic toattempt to provide procedures for the disjointment of every type of part;
guidance regarding other routes to gather additional information on certain substances in aproduct, although the information collected has relevance to the sampling strategies in thisdocument;
safe disassembly and mechanical disjointment instructions related to electrotechnicalproducts (e.g. mercury-containing switches) and the recycling industry (e.g. how to handleCRTs or the safe removal of batteries). See lEC 62554 [1]1 for the disjointment andmechanical sample preparation of mercury-containing fluorescent lamps;
sampling procedures for packaging and packaging materials;
analytical procedures to measure the levels of certain substances.This is covered by otherstandards (e.g. other parts of the lEC 62321 series)，which are referred to as “teststandards” in this document;
– guidelines for assessment of compliance.
This document has the status of a horizontal standard in accordance with IEC Guide 108 [2].

composite testing
testing of two or more materials as a single sample that could be mechanically disjointed ifnecessary
3.1.2
certain substance
substance subject to test methods developed or under development in IEC 62321(all parts),such as cadmium, lead,mercury, hexavalent chromium,polybrominated biphenyl,polybrominated diphenyl ether, phthalates
Note 1 to entry: IEC 62321-1 includes test methods for the evaluation of each of the substances identified in thedefinition above.
3.1.3
disassembly
process whereby an item is taken apart in such a way that it could subsequently be reassembledand made operational
3.1.4
disjointment
process whereby materials are separated by mechanical means such that the item cannotsubsequently be reassembled to make it operational
3.1.5
homogeneous material
one material of uniform composition throughout or a material, consisting of a combination ofmaterials, that cannot be disjointed or separated into different materials by mechanical actionssuch as unscrewing,cutting, crushing. grinding and abrasive processes.IEC 62321-2 pdf download.
