Standard Specification for Copper Alloy Bullet Jacket Cups

ABSTRACT
This specification covers bullet jacket preform cups made from UNS C22000 wrought copper alloy used for processing Types I-IV and Classes I-II bullet jackets. This standard contains information on chemical composition, grain size and testing requirements for the preform cups.
SIGNIFICANCE AND USE
15.1 For the purpose of determining compliance with the specified limits for requirements of the properties listed in the following table, an observed value, or a calculated value, shall be rounded as indicated in accordance with the rounding method of Practice E29.    
Property  
Rounded Unit for Observed or Calculated Value  
Chemical Composition  
Nearest unit in the last right-hand significant digit used in expressing the limiting value  
Grain size  
Nearest multiple of 0.005 mm
SCOPE
1.1 This specification establishes the requirements for bullet jacket preform cups produced of Copper Alloy UNS No. C22000 for processing into bullet jackets of the following types and classes:  
1.1.1 Type I—Caliber 0.30.  
1.1.2 Type II—Caliber 0.45.  
1.1.3 Type III—Caliber 0.50.  
1.1.4 Type IV—As specified in the contract or order.  
1.1.5 Class I—Not annealed.  
1.1.6 Class II—Annealed.  
1.2 Units—The values stated in inch-pound units are to be regarded as standard, except for grain size, which is given in SI units. The values in parentheses are mathematical conversions to SI units, which are provided for information only and are not considered standard.  
1.3 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.

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.
