JB/T 7092-2008Methods for measuring basic properties of silver-based clad contacts (English PDF)

JB/T 7092-2008 is the English-translated version of 银基复层电触头基本性能测量方法.

JB/T 7092-2008 is a recommended Chinese machinery industry standard giving measurement methods for the basic properties of multilayer silver-based electrical contacts.

The properties it treats are the Vickers hardness of the working layer and of the base layer, the bond strength between the layers, the spherical radius and the cone angle, the shape and thickness of the working layer, and concentricity.

The methods are intended for multilayer silver-based contacts of flat sheet or rivet type produced by various processes. It sits under Chinese classification K14 and international classification 29.120.20, was issued by the Ministry of Industry and Information Technology, replaces JB/T 7092-1993, and quotes GB/T 4340.1-1999.
