Determination of certain substances in electrotechnical products - Mercury in polymers, metals and electronics by CV-AAS, CV-AFS, ICP-OES and ICP-MS1 Scope This part of IEC 62321 describes test methods for mercury in polymers, metals and electronics by CV AAS, CV AFS, ICP OES and ICP MS. This standard specifies the determination of the levels of mercury (Hg) contained in electrotechnical products. These materials are polymers, metals and electronics (e. g. printed wiring boards, fluorescent lamps, mercury switches). Batteries containing Hg should be handled as described in [1]1. The
