ASTM B248-01

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.
Designation: B 248–98248 – 01
Standard Specification for
General Requirements for Wrought Copper and Copper-
1
Alloy Plate, Sheet, Strip, and Rolled Bar
This standard is issued under the fixed designation B 248; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the Department of Defense.

The UNS system for copper and copper alloys (see Practice E 527E 527) is a simple expansion of the former standard designation system accomplished by the addition
of a prefix “C” and a suffix “00”. The suffix can be used to accommodate composition variations of the base alloy.
