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.
Scope
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.
