Standard Specification for Copper-Beryllium Seamless Tube (UNS Nos. C17500 and C17510)

SCOPE
1.1 This specification establishes the requirements for copper-beryllium alloy seamless tube in straight lengths. Copper-cobalt-beryllium alloy UNS No. C17500 and copper-nickel-beryllium alloy UNS No. C17510 will be the alloys furnished whenever this specification is specified.  
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.3 The following safety hazard caveat pertains only to the test method(s) described in 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 to determine the applicability of regulatory limitations prior to use.
