Description

ASTM E1473-22

Active Standard: Standard Test Methods for Chemical Analysis of Nickel, Cobalt, and High-Temperature Alloys

ASTM E1473

Scope

1.1 These test methods describe the chemical analysis of nickel, cobalt, and high-temperature alloys having chemical compositions within the following limits:

1.2 The test methods in this standard are contained in the sections indicated as follows:

1.3 Other test methods applicable to the analysis of nickel alloys that may be used in lieu of or in addition to this method are E1019, E1834, E1835, E1917, E1938, E2465, E2594, E2823.

1.4 Some of the composition ranges given in 1.1 are too broad to be covered by a single method, and therefore, these test methods contain multiple methods for some elements. The user must select the proper test method by matching the information given in the scope and interference sections of each test method with the composition of the alloy to be analyzed.

1.5 Units—The values stated in SI units are regarded as standard.

1.6 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. Specific caution and hazard statements are given in Section 7 and in 13.4, 15.1.1, 15.1.2, 21.2, 22.3, 57.3, 84.2, 114.5, 115.14, 130.4, 130.5, 138.5, and 138.6.

1.7 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.
