Codeofchina.com is in charge of this English translation. In case of any doubt about the English translation, the Chinese original shall be considered authoritative. This standard is developed in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 21181-2007 Secondarily lead and lead alloy ingots. The following technical content changes have been made with respect to GB/T 21181-2007: ——Three designations ZSPb99.98, ZSPb99.95 and ZSPb98.00 are canceled; ——Two designations ZSPb99.994 and ZSPb99.992 are added. This standard was proposed by the China Nonferrous Metals Industry Association. This standard was prepared by National Technical Committee on Nonferrous Metals of Standardization Administration of China (SAC/TC 243). Secondarily lead and lead alloy ingots 1 Scope This standard specifies the requirements, test methods, inspection rules, marking, packaging, transportation, storage, quality certificate and order form (or contract) contents of secondarily lead and lead alloy ingots.
