1   Scope This International Standard specifies a method of measuring the case-hardened depth, surface hardening depth, nitriding hardness depth and total thickness of surface-hardened depth, obtained, for example, by mechanical (shot blasting, shot peening, etc.), thermal (flame induction hardening, electron beam hardening, laser beam hardening etc.) or thermochemical (carbonitriding, carburizing and hardening, hardening and nitriding, etc.) treatment.
