Scope

This Standard specifies determination method of nitrided case depth,
examination method and technical requirements for metallographic
microstructure before and after nitriding.
This Standard is applicable to the determination and evaluation on nitrided case
depth, brittleness, porosity and nervation and wave like nitride on the surface
of steel and iron parts which are treated by gas nitriding, ion nitriding,
nitrocarburizing treatment.
