1 Scope

GB/T 26054-2010 is the Chinese national standard on reproduced composition powder of cemented carbide, in the field of metallurgy. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 10 January 2011 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 October 2011. Classification: ICS 77.160, CCS H71. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the carbide recycled mixture (hereinafter referred to as recycled mixtures) requirements, test methods, inspection rules, marks, packages Equipment, transportation, storage, quality certificates and contracts (or orders) content. This standard applies to the processing of recycled carbide recycled mixtures.
