Scope
This standard specifies the requirements, test methods, inspection rules, packaging, storage, and quality forecast sheets for lead anode sludge, as well as the content of contracts (or purchase orders).
This standard applies to the insoluble substances produced during the electrolytic refining process of lead anodes, which are used for the extraction of precious metals and other valuable elements.
