GB/T 39560.5-2021
Determination of certain substances in electrical and electronic products—Part 5: Cadmium，lead and chromium in polymers and electronics and cadmium and lead in metals by AAS，AFS，ICP-OES and ICP-MS (English Version)

Scope: This part of GB/T 39560 describes the methods for the determination of lead, cadmium and chromium in polymers, metals and electronic parts by AAS, AFS, ICP-OES and ICP-MS. This part specifies the determination of cadmium (Cd), lead (Pb) and chromium (Cr) content in electrical and electronic products. It covers three types of substrates: polymer/polymer components, metals and alloys, and electronics. The sample in this section refers to the object of processing and testing. Samples and how they are obtained are determined by the institution performing the testing. See IEC 62321 2 for further guidance on how to obtain representative samples for the detection of restricted substances in electronic products. sample selection and/or
