A superscriptepsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope*1.1 This specification establishes the requirements for seam-less copper water tub
3、e suitable for general plumbing, similarapplications for the conveyance of fluids, and commonly usedwith solder, flared, or compression-type fittings. The type ofcopper water tube suitable for any particular application isdetermined by the internal or external fluid pressure, by theinstallation and
4、service conditions, and by local requirements.Means of joining or bending are also factors which affect theselection of the type of tube to be used.2NOTE 1Annealed tube is suitable for use with flared or compressionfittings, and with solder-type fittings, provided rounding and sizing of thetube ends
5、 is performed where needed.NOTE 2Drawn temper tube is suitable for use with solder-typefittings. Types K and L tube, in the drawn temper, are suitable for use withcertain types and sizes of compression fittings.NOTE 3This specification is the inch-pound companion to Specifica-tion B88M; therefore, n
6、o SI equivalents are presented in the specification.NOTE 4Fittings used for soldered or brazed connections in plumbingsystems 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 them,unless ot
