1.1 本试验方法涵盖了镍合金中0.3%至5.0%范围内钛的测定。使用适当的参考物质，测试方法可扩展至0.05%。 1.2 钼(如果存在)可导致高偏压，达到每1%钼0.001%钛的程度。 1.3 以SI单位表示的值将被视为标准值。本标准不包括其他计量单位。 1.4 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践并确定法规限制的适用性。 有关使用本试验方法的具体危害，请参见实践 E50 . 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ======意义和用途====== 5.1 本试验方法用于测定镍合金样品中的钛，以检查是否符合成分质量标准。假设所有使用该程序的人员都是训练有素的分析员，能够熟练和安全地执行常见的实验室程序。预计这项工作将在设备适当的实验室进行，并遵循适当的废物处理程序。必须遵循适当的质量控制实践，如指南中所述 E882 .

1.1 This test method covers the determination of titanium in nickel alloys in the range 0.3 % to 5.0 %. With appropriate reference materials, the test method may be extended down to 0.05 %. 1.2 Molybdenum, if present, may cause a high bias to the extent of 0.001 % titanium for every 1 % molybdenum. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 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 associated with the use of this test method, see Practices E50 . 1.5 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 used for the determination of titanium in nickel alloy samples to check for compliance with compositional specifications. It is assumed that all who use the procedure 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 and that proper waste disposal procedures will be followed. Appropriate quality control practices must be followed such as those described in Guide E882 .
