Scope*1.1 This specification covers requirements, test methods,and methods of marking for chlorinated poly(vinyl chloride)plastic hot- and cold-water distribution system componentsmade in one standard dimension ratio and intended for waterservice up to and including 180F (82
4、C). These componentscomprise pipe and tubing, socket-type fittings, street fittings,plastic-to-metal transition fittings, solvent cements, and adhe-sives. Requirements and methods of test are included formaterials, workmanship, dimensions and tolerances, hydro-static sustained pressure strength, and
5、 thermocycling resis-tance. The components covered by this specification areintended for use in residential and commercial, hot and cold,potable water distribution systems.1.2 The products covered by this specification are intendedfor use with the distribution of pressurized liquids only, whichare c
6、hemically compatible with the piping materials. Due toinherent hazards associated with testing components and sys-tems with compressed air or other compressed gases somemanufacturers do not allow pneumatic testing of their products.Consult with specific product/component manufacturers fortheir speci
7、fic testing procedures prior to pneumatic testing.NOTE 1Pressurized (compressed) air or other compressed gasescontain large amounts of stored energy which present serious safteyhazards should a system fail for any reason.1.3 The text of this specification references notes, footnotes,and appendixes w
8、hich provide explanatory material. Thesenotes and footnotes (excluding those in tables and figures) shallnot be considered as requirements of the specification.1.4 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. The values stated ineach system may n
9、ot be exact equivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.NOTE 2Suggested hydrostatic design stresses and hydrostatic pres-sure ratings for pipe, tubing, and fittings are listed in Appe
10、ndix X1.Design, assembly, and installation considerations are discussed in Appen-dix X2. An optional performance qualification and an in-plant qualitycontrol program are recommended in Appendix X3.1.5 The following safety hazards caveat pertains only to thetest method portion, Sections 9 and 10, of
11、this specification:This standard does not purport to address all of the safetyconcerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety andhealth practices and determine the applicability of regulatorylimitations prior to use.2. R
