ASTM - B601 REV A
Standard Practice for Temper Designations for Copper and Copper Alloys - Wrought and Cast
|Publication Date:||10 September 1999|
|ICS Code (Copper products):||77.150.30|
1.1 This practice defines the terminology in general use for indicating the temper of copper and copper alloy products. The designations used in ASTM specifications under the jurisdiction of Committee B-5 will conform to this practice.
1.2 It defines the terminology of the processes that produce the tempers and the observable changes in the product that result from the processes.
1.3 It establishes an alphanumeric code for use in designating the product tempers.
1.3.1 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. These letters are frequently the same as those used in temper systems of other metals, and are applied to copper products in accordance with this practice.
1.3.2 The numbers in the code were chosen subjectively for general tempers, and objectively to indicate grain size for annealed tempers or reductions for cold-worked tempers.
1.4 The use of this code is recommended for all product tempers in specifications and published data. Its use will simplify the presentation of property data when in tabular form.
1.5 The property requirements for the tempers are given in applicable product specifications.
1.6 Where the word "product" is used, it means a copper or copper alloy product.
1.7 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.
