Scope*1.1 This specification establishes the r
3、equirements for seamless copper-nickel pipe and tube in straight lengths, suitable forgeneral engineering purposes. The alloys involved are copper alloys UNS Nos. C70400, C70600, C70620, C71000, C71500,C71520, and C72200.1.1.1 Copper alloys UNS Nos. C70620 and C71520 are intended for product that wi
4、ll be subsequently welded.1.2 UnitsValues stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, SI unitsare shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be usedindependently of the o
5、ther. Combining values from the two systems may result in nonconformance with the specification.1.3 The following safety hazard caveat pertains only to the test methods described in this specification:1.3.1 This standard does not purport to address all of the safety concerns, if any, associated with
6、 its use. It is the responsibilityof the user of this standard to establish appropriate safety safety, health, and healthenvironmental practices and determine theapplicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally reco
