Determination of certain substances in electrotechnical products - Screening. Lead, mercury, cadmium, total chromium and total bromine by X-ray fluorescence spectrometry Ingestion-build-232773 It applies to products for1 Scope Part 3 1 of IEC 62321 describes the screening analysis of five substances, specifically lead (Pb), mercury (Hg), cadmium (Cd), total chromium (Cr) and total bromine (Br) in uniform materials found in electrotechnical products, using the analytical technique of X ray fluorescence (XRF) spectrometry. It is applicable to polymers, metals and ceramic materials. The test method may be applied to raw materials, individual materials taken from
