Scope

1.1 This test method covers the determination of titanium in nickel alloys in the 0.3 through 5.0 % range. 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 % Ti for every 1 % Mo.

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 and health practices and determine the applicability of regulatory limitations prior to use. For specific hazards associated with the use of this test method see Practices E 50.

Significance and Use

This practice is used for the analysis of nickel and nickel base alloy samples by molecular absorption spectrometry to check 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 E 882.
