Abstract
This specification establishes the requirements for seamless copper and copper alloy tubing on which the external or internal surface, or both, has been modified by a coldforming process to produce an integral enhanced surface for improved heat transfer. The tubes are typically used in surface condensers, evaporators, and heat exchangers. The seamless copper and copper alloy tubing shall have the internal or external surface, or both, modified by a cold forming process to produce an integral enhanced surface for improved heat transfer. The tube, after enhancing, shall be supplied in the annealed (O61) or as-fabricated temper. The enhanced sections of tubes in the as-fabricated temper are in the cold-worked condition produced by the fabricating operation. The unenhanced sections of tubes in the asfabricated temper are in the temper of the tube prior to enhancing, annealed (O61), or light drawn (H55), and suitable for rolling-in operations. Samples of annealed-temper (O61) tubes selected for test shall be subjected to microscopical examination and shall show uniform and complete recrystallation. Grain size and mechanical properties such as tensile strength and yield strength of the alloys shall be determined. Expansion and flattening tests shall be done to the alloys for performance evaluation. Non-destructive tests such as eddy-current test, hydrostatic test, and pneumatic test shall be done as well.

Note 1: Designations listed in Classification B224.
1.4 Units—The values stated in either in-pound units or SI units are to be regarded separately as the standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems could result in nonconformance with the specification.
1.5 Product produced in accordance with the Supplementary Requirements section for military applications shall be produced only to the inch-pound system of this specification.
1.6 The following safety hazard caveat pertains only to the test methods 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 determine the applicability of regulatory limitations prior to use. Some specific hazards statements are given in Sections 1, 12 and 18.
1.7 (Warning—Mercury has been designated by many regulatory agencies as a hazardous material 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 into your state or country may be prohibited by law.)
