ASTM B62-17

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: B62 − 15 B62 − 17
Standard Specification for
Composition Bronze or Ounce Metal Castings
This standard is issued under the fixed designation B62; 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 U.S. Department of Defense.
1. Scope*
1.1 This specification establishes requirements for an alloy having a composition of copper, tin, lead, and zinc, used for
component castings of valves, flanges, and fittings. The common trade name of this alloy is 85-5-5-5; the correct identification is
Copper Alloy UNS No. C83600.
1.2 The castings covered are used in products that may be manufactured in advance and supplied from stock from the
manufacturer or other dealer.
1.3 Units—The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are
mathematical conversions to SI units thatunits, which are provided for information only and are not considered standard.
1.4 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.

Current edition approved May 1, 2015April 1, 2017. Published May 2015May 2017. Originally approved in 1926. Last previous edition approved in 20092015 as
B62 – 09.B62-15. DOI: 10.1520/B0062-15.10.1520/B0062-17.
For ASME Boiler and Pressure Vessel Code applications see related Specification SB-61 of that Code.
The UNS system for copper and copper alloys (see Practice E527) 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.
