Scope*1.1 This specification covers
3、poly(vinyl chloride) (PVC)threaded Schedule 80 pipe fittings. Included are requirementsfor materials, workmanship, dimensions, and burst pressure.NOTE 1Threaded CPVC plastic pipe fittings, Schedule 80, whichwere formerly included in this standard, are now covered by SpecificationF437.1.2 The product
4、s covered by this specification are intendedfor use with the distribution of pressurized liquids only, whichare chemically compatible with the piping materials. Due toinherent hazards associated with testing components and sys-tems with compressed air or other compressed gases somemanufacturers do n
5、ot allow pneumatic testing of their products.Consult with specific product/component manufacturers fortheir specific testing procedures prior to pneumatic testing.NOTE 2Pressurized (compressed) air or other compressed gasescontain large amounts of stored energy which present serious safetyhazards sh
6、ould a system fail for any reason.1.3 The text of this specification references notes, footnotes,and appendixes which 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 in
7、ch-pound units are to be regardedas the standard. The values given in parentheses are providedfor information only.1.5 The following safety hazards caveat pertains only to thetest method portion, Section 8, of this specification. Thisstandard does not purport to address all of the safety concerns,if
8、 any, associated with its use. It is the responsibility of the userof this standard to establish appropriate safety and healthpractices and determine the applicability of regulatory limita-tions prior to use.2.

16、n4.1 GeneralThis specification covers threaded Schedule80 PVC pipe fittings, made from four PVC plastic compoundsand intended for use with threaded Iron Pipe Size (IPS)outside-diameter plastic pipe.4.1.1 Fittings covered by this specification are normallymolded. In-line fittings, such as couplings,
17、unions, bushings,caps, nipples, etc., shall be molded or machined from extrudedstock.4.1.2 Fittings fabricated by back welding or butt fusion arenot included in this specification.5. Materials and Manufacture5.1 This specification covers PVC pipe fittings made fromtwo PVC plastics as classified in S
18、pecification D1784. Theseare cell classifications 12454 and 14333.NOTE 3Mechanical strength, heat deflection temperature, and flam-mability requirements are covered in Specification D1784.5.2 Rework MaterialThe manufacturers shall use onlytheir own clean rework fitting material and the fittings pro-
19、duced shall meet all the requirements of this specification.6.

Minimum dimensions have zeronegative tolerances. Bus
20、hings shall have thread lengths appli-cable to the corresponding sizes. Counterbore is optional, is notshown in Table 1, and is not included in the center-to-end orend-to-end dimensions.6.1.2 Fittings Not IllustratedAll fittings, whether illus-trated in Table 1 and Table 2 or not, shall have wall th
21、icknessesand thread dimensions conforming to 6.1 and 6.2.6.2 ThreadsFor all fittings having taper pipe threads,threads shall conform to Specification F1498 and be gaged inaccordance with 8.4.6.3 Burst Pressure:6.3.1 The burst strength of the fittings shall be not less thanthat calculated for the siz
22、e and wall thickness of the pipe withwhich it is to be used, when calculated from the followingequation:S 5 PDOt!/2t (1)where:S = hoop stress, psi (or MPa),P = internal pressure, psi (or MPa),DO= average outside diameter, in. (or mm), andt = minimum wall thickness, in. (or mm).Fittings tested in acc
23、ordance with 8.4 shall withstand theminimum burst pressure shown in Table 3.6.3.2 Pressures shown are minimum burst pressures and donot imply rated working pressures. The burst pressure shall beused only as an indication of quality.7. Workmanship, Finish, and Appearance7.1 The fittings shall be homo
24、geneous throughout and freeof cracks, holes, foreign inclusions, or other defects. TheTABLE 1 Dimensions of 90 Ells, Tees, Crosses, 45 Elbows and Couplings (Straight Sizes), in.
