New Test Method for Determination of Hydrogen in Iron, Steel, Nickel, and Cobalt alloys by Hot Extraction

1. Scope

1.1 This test method applies to the determination of hydrogen in iron, steel, nickel, and cobalt alloys in mass fractions from 0.0000X to 0.0000X % by hot extraction using thermal conductivity detection where the maximum method temperature is less than 1200C to prevent sample melting. 1.2 This test method has been interlaboratory tested for the quantification ranges specified in 1.1. The ranges in 1.1 indicate intervals within which results have been demonstrated to be quantitative. It may be possible to extend this test method to different ranges provided that a method validation study is performed and that the results of this study show that the method extension is meeting laboratory data quality objectives. Guide E2857 provides information on how to perform method validation studies. 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 precautionary statements, see Section 9.
