Scope

JB/T 12607-2016 is the English-translated version of 超硬刀具材料性能检测方法.

JB/T 12607-2016 is the Chinese machinery industry standard on inspection methods for the performance parameters of superhard tool materials. It prescribes the test methods for parameters such as chemical composition, microstructure, impact toughness, thermal shock toughness, fracture toughness, friction behaviour, wear resistance and machinability.

It applies to polycrystalline diamond superhard tool material and to polycrystalline cubic boron nitride (PCBN) superhard tool material, the latter in both the high CBN content and the low CBN content binder varieties.

Among the standards it quotes are GB/T 3810.7, GB/T 21951, GB/T 21952, JB/T 7269, JB/T 7420, JB/T 8801, JB/T 10646, JB/T 10987 and ISO 28079. It carries Chinese classification J41 and international classification 25.100.01.
