氫損傷也稱氫脆，包括氫壓引起的微裂紋、高溫高壓氫腐蝕、氫化物相或氫致馬氏體相變、氫致塑性損失等。氫脆主要涉及金屬韌性的降低，而氫損傷除涉及韌性降低和開裂外，還包括金屬材料其它物理性能或化學性能的下降，因此含義更為廣泛。

標準名稱：Evaluation of Pipeline and Pressure Vessel Steels for Resistance to Hydrogen-Induced Cracking
標準編號：NACE TM0284-2003
實施日期：2003-01-17
標準概述：This standard establishes a test method for evaluating the resistance of pipeline and pressure vessel plate steels to HIC caused by hydrogen absorption from aqueous sulfide corrosion. he test method consists of exposing unstressed test specimens to one of the two standard test solutions—either Solution A, a sodium chloride, acetic acid （NaCl,CH₃COOH） solution saturated with H₂S at ambient temperature and pressure, or Solution B, a synthetic seawater solution saturated with H₂S at ambient temperature and pressure.  After a specified time the test specimens shall be removed and evaluated.
