2、 indicates the year of last reapproval.Asuperscriptepsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope*1.1 This specification establishes the requirements for seamless copper wat
3、er tube suitable for general plumbing, similarapplications for the conveyance of fluids, and commonly used with solder, flared, or compression-type fittings. The type of copperwater tube suitable for any particular application is determined by the internal or external fluid pressure, by the installa
4、tion andservice conditions, and by local requirements. Means of joining or bending are also factors which affect the selection of the typeof tube to be used.2NOTE 1Annealed tube is suitable for use with flared or compression fittings, and with solder-type fittings, provided rounding and sizing of th
5、e tubeends is performed where needed.NOTE 2Drawn temper tube is suitable for use with solder-type fittings. Types K and L tube, in the drawn temper, are suitable for use with certaintypes and sizes of compression fittings.NOTE 3This specification is the inch-pound companion to Specification B88M; th
6、erefore, no SI equivalents are presented in the specification.NOTE 3Fittings used for soldered or brazed connections in plumbing systems are described in ASME B16.18 and ASME B16.22.1.2 The tube shall be produced from the following coppers, and the manufacturer has the option to supply any one of th
