This specification establishes the requirements for seamless tube and ferrule stock of copper and various copper alloys of a specified range of diameters, for use in surface condensers, evaporators, and heat exchangers. The specified coppers and copper alloys are UNS No. C10100, C10200, C10300, C10800, C12000, C12200, C14200, C19200, C23000, C28000, C44300, C44400, C44500, C60800, C61300, C61400, C68700, C70400, C70600, C70620, C71000, C71500, C71520, C71640, and C72200. The product shall be produced by processes such as casting, extrusion, drawing, annealing, straightening, trimming, and other processes which may produce a seamless tube in the specified condition. The coppers and copper alloys shall be specifically furnished in any one of the following tempers: annealed, light-drawn, hard-drawn, or hard drawn and end annealed. Tubes for ferrule stock shall be annealed sufficiently to be fully crystallized. Some tubes are suggested to be subjected to a stress-relieving thermal treatment subsequent to straightening. The products shall be subjected to expansion, flattening, and residual stress tests. The tensile and expansion requirements for the products are specified in accordance with the temper designation. The products shall also be subjected to mercurous nitrate, ammonia vapor, Eddy-current, hydrostatic, and pneumatic tests.

1.1 This specification2 establishes the requirements for seamless tube and ferrule stock of copper and various copper alloys up to 3¹/₈ in. [80 mm] inclusive, in diameter, for use in surface condensers, evaporators, and heat exchangers. The following coppers and copper alloys are specified:3

1.2 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

1.3 The following safety hazards caveat pertains only to the test methods portion, Section 19, 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. (Warning—Mercury has been designated by many regulatory agencies as a hazardous substance that can cause serious medical issues. Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive to materials. Caution should be taken when handling mercury and mercury containing products. See the applicable product Safety Data Sheet (SDS) for additional information. Users should be aware that selling mercury and/or mercury containing products in your state or country may be prohibited by law.)
