Revised Standard from Last Update.

1. SCOPE

1.1 This standard specifies a method of determining (the magnetization) coercivity of hardmetals containing not less than 3 percent of a ferromagnetic binder by mass.

1.2 This test method also allows the non-destructive estimate of average grain size in sintered hard metals. It is also appropriate for a wide range of compositions and tungsten carbide (WC) WC grain sizes, and can be used for acceptance of material or product to specification.
