Designation: B 22 – 02
Standard Specification for
Bronze Castings for Bridges and Turntables
1
This standard is issued under the fixed designation B 22; 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 (e) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the Department of Defense.
1. Scope *
1.1 This specification establishes requirements for bronze
castings for turntables, movable bridges and bridge parts, and
bronze castings suitable for use in bridges and other structures
for fixed and expansion bearings in which motion is slow and
intermittent. The following Copper Alloys are specified: UNS
No. C86300, C90500, C91100, C91300, and C93700.
NOTE 1—Historically, the alloys in this specification have been used in
the applications listed in Appendix X1. Actual practice may vary.
2
1.2 Units—The values stated in inch/pound or SI units are
to be regarded separately as standard. The values stated in each
system may not be exact equivalents; therefore, each system
shall be used independently of the other. Combining values
from the two systems may result in nonconformance with the
specification.
1.3 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 appro-
priate safety and health practices and determine the applica-
bility of regulatory limitations prior to use.

5. Ordering Information
5.1 Include the following information when placing order
1
This specification is under the jurisdiction ofASTM Committee B05 on Copper
and Copper Alloys and is the direct responsibility of Subcommittee B05.05 on
Castings and Ingots for Remelting.
Current edition approved Oct. 10, 2002. Published November 2002. Originally
published as B 22 – 36 T. Last previous edition B 22 – 95.
This specification was prepared in cooperation with representatives of the
American Association of State Highway Officials and the American Railway
Engineering Association.

The UNS system for copper and copper alloys (see Practice E 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.
