Anotace textu normy ASTM B543/B543M-18 :
This specification covers welded tube of specific copper and various copper alloys of a limited range of diameters, for use in surface condensers, evaporators, heat exchangers, and general engineering applications. The product shall be manufactured by forming the material into a tubular shape on a suitable forming mill. Welding of tube shall be accomplished by forge-welding, fusion-welding, or full finishing that produces a forge weld leaving no crevice in the weld seam visible to the unaided eye. The tube shall conform to tensile strength and yield strength requirements, and shall be subject to expansion, flattening, and reverse bend tests. Mercurous nitrate or ammonia vapor tests shall be required only for selected UNS Numbers of Copper Alloys. Each tube shall be subjected to eddy-current, hydrostatic, and pneumatic tests.

1.2 The values stated in either inch-pound or SI units are to be regarded separately as standard. Within the text, SI units are shown in brackets. 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 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, health, and environmental 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. Use caution when handling mercury and mercury-containing products. See the applicable product Safety Data Sheet (SDS) for additional information. The potential exists that selling mercury or mercury-containing products, or both, is prohibited by local or national law. Users must determine legality of sales in their location.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
