(Classification)Standard Classification for Temper Designations for Copper and Copper Alloys—Wrought and Cast
Standard Classification for Temper Designations for Copper and Copper Alloys—Wrought and Cast
SIGNIFICANCE AND USE
4.1 Significance—This classification establishes an alphanumeric code of the tempers of copper and copper alloy products.
4.2 Use—An alphanumeric code establishes a system by which product tempers in specifications and published data are designated.
4.2.1 The letters in the code identify the type of process used to produce the product temper. For example, “H” indicates a temper resulting from cold working.
Note 1: These letters are frequently the same as those used in temper systems of other metal products.
Note 2: Undefined letters, used in prior temper systems and included in this system for reference, are defined in Appendix X1.
SCOPE
1.1 This classification establishes temper designations for copper and copper alloys—wrought and cast. The temper designations are classified by the process or processes used in manufacturing the product involved and its resulting properties. It is not a specification of copper and copper alloys.
1.2 The property requirements for the tempers are given in the applicable product specification.
1.3 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
