1. Scope

1.1 This specification covers welded tube of copper and various copper alloys up to 31/8 in., inclusive, in diameter, for use in surface condensers, evaporators, heat exchangers, and general engineering applications. Tubes for this application are normally made of the following coppers or copper alloys:

1.2 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. ( Warning Mercury is a definite health hazard in use and disposal. (See 14.1.))

Note 1A complete metric companion to Specification B 543 has been developedB 543M; therefore, no metric equivalents are presented in this specification.
