This standard specifies the requirements, test methods, inspection rules and signs, packaging, transportation and storage of secondary lead and lead alloy ingots. This standard applies to secondary lead and its alloy ingots produced through smelting and processing of lead-containing waste as raw materials. It is mainly used in electrolytic refining, storage batteries, alloys and chemical industries.
