4、up to and including 180F (82C). These components comprise pipe and tubing, socket-type fittings, street fittings, plastic-to-metaltransition fittings, solvent cements, and adhesives. Requirements and methods of test are included for materials, workmanship,dimensions and tolerances, hydrostatic susta
5、ined pressure strength, and thermocycling resistance. The components covered by thisspecification are intended for use in residential and commercial, hot and cold, potable water distribution systems.1.2 The products covered by this specification are intended for use with the distribution of pressuri
6、zed liquids only, which arechemically compatible with the piping materials. Due to inherent hazards associated with testing components and systems withcompressed air or other compressed gases some manufacturers do not allow pneumatic testing of their products. Consult withspecific product/component
7、manufacturers for their specific testing procedures prior to pneumatic testing.NOTE 1Pressurized (compressed) air or other compressed gases contain large amounts of stored energy which present serious safetysaftey hazardsshould a system fail for any reason.1.3 The text of this specification referenc

Materials5.1 Basic Materials DescriptionChlorinated poly(vinyl chloride) plastics used to make pipe, tubing, and fittings meeting therequirements of this specification are categorized by two criteria; namely, basic short-term properties, and lon
38、g-term hydrostaticstrength. Sections 5.1.1 and 5.1.2 respectively define these categories.5.1.1 Basic Short-Term PropertiesThis specification covers CPVC 41 pipe, tubing, and fittings made from plastic materialsmeeting the mechanical strength, heat resistance, flammability, and chemical resistance r
39、equirements for CPVC 23447 inSpecification D1784.NOTE 4CPVC 23447 was formerly designated as CPVC Type IV Grade 1, and is herein designated as CPVC 41.

41、D2837. Fittings are so defined by hydrostatic sustained pressure tests on fitting assemblies, requiredby this specification (see 6.2), based on the hydrostatic strength of the corresponding pipe or tubing.NOTE 5No hydrostatic design stress, as such, exists for fittings until such time as long-term h
