本国际标准规定了一种测量表面硬化深度、表面硬化深度、渗氮硬度深度和表面硬化深度总厚度的方法，例如通过机械（喷丸、喷丸等）获得，热（火焰感应硬化、电子束硬化、激光束硬化等）或热化学（碳氮共渗、渗碳和硬化、硬化和氮化等）处理。

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.
