Standard Specification for Seamless Copper Tube [Metric]

SCOPE
1.1 This specification establishes the requirements for seamless round, rectangular, and square copper tube suitable for general engineering applications.  
1.1.1 Tubes made from any of the following Copper UNS No. designations may be supplied unless otherwise specified in the contract or purchase order:  
Copper UNS No. Type of Copper C10100 Oxygen-free electronic C10200 Oxygen-free without residual deoxidants C10300 Oxygen-free, extra low phosphorus C10800 Oxygen-free, low phosphorus C12000 Phosphorus deoxidized, low residual phosphorus C12200 Phosphorus deoxidized, high residual phosphorus
1.2 The values stated in SI units are the standard.
1.3 This specification is the companion to inch-pound Specification B 75.
1.4 The following hazard statement pertains only to the test method described in Sections 20.5.2.1, 21.2.9, and 21.2.10 of this specification: 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 appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
