Scope
GB/T 10560-2017 is the English-translated version of 矿用焊接圆环链用钢.
GB/T 10560-2017 is the Chinese national standard on steels for welded round link chains for mines, 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 12 July 2017 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 April 2018.
Classification: ICS 77.140.60, CCS H44. 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.
