Scope Scope*1.1 This specification covers seamless c
3、opper water tube suitable for general plumbing, similar applications for the conveyanceof fluids, and commonly used with solder, flared, or compression-type fittings. The type of copper water tube suitable for anyparticular application is determined by the internal or external fluid pressure, by the
4、 installation and service conditions, and by localrequirements. Means of joining or bending are also factors that affect the selection of the type of tube to be used.2NOTE 1Annealed tube is suitable for use with flared or compression fittings, and with solder-type fittings, provided rounding and siz
