1 Scope

This document specifies the strategy for sampling and mechanical preparation of samples from electrical and electronic products. These samples can be used for other IEC 62321 Some of the standardized test methods are used to analyze and test the content of certain substances. The restrictions on substances vary from region to region and from time to time. This document describes this document describes a general procedure for obtaining and preparing samples prior to assaying for substances of interest.

This document does not provide the following.

---Detailed guidance for each product that is classified as electrical and electronic equipment.

With the continuous innovation of electronic electrical equipment and the industry, it is unrealistic to try to provide the disassembly process of all kinds of electronic components.

--- Guidance on collecting additional information on certain substances in products through other means, even if the information collected according to the guidance is different from that in this document Sampling strategy related.

---Electrical and electronic products (e.g. mercury-containing switches) and the recycling industry [e.g. how to handle cathode ray tubes (CRTs) or batteries safely for the disassembly and mechanical sample preparation of mercury-containing fluorescent lamps, see IEC 62554.

--- Sampling procedures for packaging and packaging materials.

--- Analytical procedures designed to determine the content of certain substances. Other parts referred to as "test standards" in this series of standards (for example.

Other parts of IEC 62321) deal with these analysis procedures.
