3、y(vinyl chloride) (PVC) pipe made in standard thermoplastic pipe dimension ratios andpressure rated for water (see appendix). Included are criteria for classifying PVC plastic pipe materials and PVC plastic pipe, asystem of nomenclature for PVC plastic pipe, and requirements and test methods for mat
4、erials, workmanship, dimensions,sustained pressure, burst pressure, flattening, and extrusion quality. Methods of marking are also given.1.2 The products covered by this specification are intended for use with the distribution of pressurized liquids only, which arechemically compatible with the pipi
5、ng 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 manufacturers for their specific testing procedures prior to
6、pneumatic testing.NOTE 1Pressurized (compressed) air or other compressed gases contain large amounts of stored energy which present serious safety hazards shoulda system fail for any reason.NOTE 2This standard specifies dimensional, performance and test requirements for plumbing and fluid handling a

11、ix, are calculated from stress values obtained fromtests made on pipe 4 in. (100 mm) and smaller. However, tests conducted on pipe as large as 24 in. (600 mm) in diameter have shown these stress valuesto be valid for larger diameter PVC pipe.NOTE 5PVC pipe made to this specification is often belled
