本条款定义了美国运输部（DOT）危险品法规下的第8类腐蚀性物质。核心标准包括：在接触部位造成人体皮肤不可逆损伤，或对钢/铝具有严重腐蚀速率。规定应优先使用§173.137授权的体外测试方法或历史数据判定。同时明确PHMSA有权根据实际危害调整分类，并允许使用1995年9月30日前依据旧附录A产生的皮肤腐蚀测试数据进行包装组别分配。该定义直接决定货物是否按Class 8进行申报、包装及运输。

(a) For the purpose of this subchapter, “corrosive material” (Class 8) means a liquid or solid that causes irreversible damage to human skin at the site of contact within a specified period of time. A liquid, or a solid which may become liquid during transportation, that has a severe corrosion rate on steel or aluminum based on the criteria in § 173.137(c)(2) is also a corrosive material. Whenever practical, in vitro test methods authorized in § 173.137 of this part or historical data authorized in paragraph (c) of this section should be used to determine whether a material is corrosive.
(b) If human experience or other data indicate that the hazard of a material is greater or less than indicated by the results of the tests specified in paragraph (a) of this section, PHMSA may revise its classification or make the determination that the material is not subject to the requirements of this subchapter.
(c) Skin corrosion test data produced no later than September 30, 1995, using the procedures of part 173, appendix A, in effect on September 30, 1995 (see 49 CFR part 173, appendix A, revised as of October 1, 1994) for appropriate exposure times may be used for classification and assignment of packing group for Class 8 materials corrosive to skin.
