YS/T 1886-2026Linearly reciprocating wear test method for hardmetals (English PDF)

YS/T 1886-2026 is the English-translated version of 硬质合金直线往复磨损试验方法.

This test method describes how to measure the wear amount of hardmetals (including steel-bonded hardmetals) by the linear reciprocating friction method. It applies to measuring the wear amount of hardmetals (including steel-bonded hardmetals) whose Rockwell hardness is not more than 90 HRA.

Cemented carbide producers, makers of tools and wear parts, materials research and test laboratories, and buyers who compare the wear behaviour of different hardmetal grades can use it. A common method allows results from different laboratories to be compared on the same basis. YS/T 1886-2026 is a voluntary standard (code with /T). It was approved and issued by the Ministry of Industry and Information Technology on 15 July 2026 and takes effect on 1 February 2027. The translated edition lets foreign laboratories and customers apply the method in the same form as Chinese users.
