1.1 本试验方法适用于测定质量分数为9的活性金属和活性金属合金中的氢，尤其是钛和锆 毫克/千克至320 毫克/千克。 1.2 该方法已在实验室间对钛和锆以及这些金属的合金进行了测试，可以在中规定的范围内提供定量结果 1.1 . 如指南中所述，通过方法验证研究，可以扩大该方法的定量范围 E2857 研究结果表明，方法扩展满足实验室数据质量目标。如指南中所述，如果进行了方法验证研究，该方法也可以扩展到除钛和锆以外的合金 E2857 ，执行。 1.3 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。 有关具体危险，请参阅第节 9 . 1.4 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。 ====意义和用途====== 5.1 本试验方法用于活性金属和活性金属合金的常规分析，以验证是否符合成分规范，如B09和B10委员会规定的成分规范。 预计所有使用该测试方法的人都将是经过培训的分析员，能够熟练、安全地执行常见的实验室程序。预计这项工作将在配备适当的实验室中进行。

1.1 This test method applies to the determination of hydrogen in reactive metals and reactive metal alloys, particularly titanium and zirconium, with mass fractions from 9 mg/kg to 320 mg/kg. 1.2 This method has been interlaboratory tested for titanium and zirconium and alloys of these metals and can provide quantitative results in the range specified in 1.1 . It may be possible to extend the quantitative range of this method provided a method validation study, as described in Guide E2857 , is performed and the results of the study show the method extension meets laboratory data quality objectives. This method may also be extended to alloys other than titanium and zirconium provided a method validation study, as described in Guide E2857 , is performed. 1.3 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. For specific hazards, see Section 9 . 1.4 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. ====== Significance And Use ====== 5.1 This test method is intended for the routine analysis of reactive metals and reactive metal alloys to verify compliance with compositional specifications such as those specified by Committees B09 and B10. It is expected that all who use this test method will be trained analysts capable of performing common laboratory procedures skillfully and safely. It is expected that the work will be performed in a properly equipped laboratory.
