1.1 这些测试方法和实践包括与钢、不锈钢和相关合金的化学分析相关的定义、参考方法、实践和指南。它们包括湿化学和仪器技术。 1.2 提供了处理化学要求、产品分析、残留元素和参考标准以及处理和报告化学分析数据的说明。 1.3 这些测试方法和实践仅适用于作为要求包括这些测试方法和实践或其部分的产品标准。 1.4 如有冲突，产品规范要求应优先于这些测试方法和实践的要求。 1.5 请注意ISO/IEC 17025时，可能需要有关测试实验室评估标准的信息。 1.6 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.7 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

1.1 These test methods and practices cover definitions, reference methods, practices, and guides relating to the chemical analysis of steel, stainless steel, and related alloys. They include both wet chemical and instrumental techniques. 1.2 Directions are provided for handling chemical requirements, product analyses, residual elements, and reference standards, and for the treatment and reporting of chemical analysis data. 1.3 These test methods and practices apply only to those product standards which include these test methods and practices, or parts thereof, as a requirement. 1.4 In cases of conflict, the product specification requirements shall take precedence over the requirements of these test methods and practices. 1.5 Attention is directed to ISO/IEC 17025 when there may be a need for information on criteria for evaluation of testing laboratories. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
