Scope
JB/T 12074-2014 is the English-translated version of 复合金属材料成分的测定 电子探针法.
JB/T 12074-2014 is a recommended Chinese machinery industry standard on the determination of composition in metallic contact materials by electron probe microanalysis.
It describes how the composition of composite and composite bimetallic electrical contact materials is determined, both qualitatively and by measurement. Light elements such as carbon and oxygen fall outside what the method covers, so the analysis is directed at the remaining elements.
The standard quotes GB/T 4930 and GB/T 15074. It carries the Chinese classification K14 and the international classification 29.120.20, and was prepared under the Ministry of Industry and Information Technology. Issued on 9 July 2014, it has applied since 1 November 2014.
