Scope
GB/T 33882-2017 is the English-translated version of 换向器用银无氧铜线坯.
GB/T 33882-2017 is the Chinese national standard for the silver oxygen-free copper drawing stock from which commutators are made, in diameters of 8 mm to 20 mm.
It covers the requirements, the test methods, the inspection rules and the marking, packaging, transport, storage, quality certificate and order.
The stock comes in the grades TUAg0.05 and TUAg0.1, with the codes T10510 and T10530, either continuously cast in the M07 state from 12.5 mm to 20 mm or hard drawn in the H04 state from 8 mm to 17 mm, and a product is designated by name, standard number, grade, state and size in that order.
For the single checks it cites GB/T methods for electrical resistance, bare wire dimensions and tensile strength, chemical analysis and hydrogen embrittlement. It was issued on 12 July 2017 and has applied since 1 February 2018.
