Active Standard: Standard Test Methods for Chemical Analysis of Copper Alloys

ASTM E478

Scope

1.1 These test methods cover the chemical analysis of copper alloys having chemical ranges within the following limits:2

1.2 The test methods appear in the following order:

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 and health practices and determine the applicability of regulatory limitations prior to use.

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.
