Organization: ASTM
Publication Date: 10 April 1996
Status: inactive
Page Count: 5
ICS Code (Copper products): 77.150.30
scope:

1. Scope *

1.1 This specification establishes the requirements for naval brass rod, bar, and shapes produced from Copper Alloys UNS No. C46200, C46400, C47940, C48200, or C48500.

1.1.1 For piston-finish rod or shafting refer to Section 9.

1.2 This specification is the companion to SI Specification B 21M; therefore no SI equivalents are shown.

1.3 Warning--Mercury is a definite health hazard in use and disposal (see 7.1).

NOTE 1--For hot forging material, refer to Specification B 124.
