1、Designation: B 88 03Standard Specification forSeamless Copper Water Tube1This standard is issued under the fixed designation B 88; the number immediately following the designation indicates the year of originaladoption or, in the case of revision, the year of last revision. A number in parentheses i
2、ndicates the year of last reapproval. A superscriptepsilon (e) 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 covers seamless copper water tubesuitable for general pl
3、umbing, similar applications for theconveyance of fluids, and commonly used with solder, flared,or compression-type fittings. The type of copper water tubesuitable for any particular application is determined by theinternal or external fluid pressure, by the installation andservice conditions, and b
4、y local requirements. Means of joiningor bending are also factors which affect the selection of thetype 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 is performed where neede
5、d.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 3A complete metric companion to Specification B 88 has beendevelopedB 88M; therefore, no metric equivalents a
6、re presented in thisspecification.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 otherwise specified.
