ASTM E1938-02
Historical Standard: ASTM E1938-02 Standard Test Method for Determination of Titanium in Nickel Alloys by Diantipyrylmethane Molecular Absorption Spectrometric Method
SUPERSEDED (see Active link, below)
ASTM E1938
1. 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.
