3、specification covers poly(vinyl chloride) (PVC)Schedule 40 pipe fittings. Included are requirements formaterials, workmanship, dimensions, and burst pressure.NOTE 1Socket-type CPVC plastic pipe fittings, Schedule 40, whichwere formerly included in this standard, are now covered by SpecificationF438.
4、1.2 The products 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, somema
5、nufacturers do not 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
6、safteyhazards should a system fail for any reason.1.3 Fitting such as unions, flanges, special plastic-to-metaltransitions and appurtenances intended for use with PVCpiping are covered under specification F1970.1.4 The text of this specification references notes, footnotes,and appendixes which provi
7、de explanatory material. Thesenotes and footnotes (excluding those in tables and figures) shallnot be considered as requirements of the specification.1.5 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that
8、are provided for information onlyand are not considered standard.1.6 The following safety hazards caveat pertains only tothe test method portion, Section 7, of this specification. Thisstandard does not purport to address all of the safety concerns,if any, associated with its use. It is the responsib
9、ility of the userof this standard to establish appropriate safety and healthpractices and determine the applicability of regulatory limita-tions prior to use.1.7 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the

35、. TheD2466 172pressure shall be applied at a uniform rate such that theminimum allowable burst pressure is attained in 60 to 70 s.NOTE 5Provided the minimum burst pressure is met or exceededbetween 60 and 70 s, the time-to-failure may exceed 70 s.9. Retest and Rejection9.1 If the results of any test
36、(s) do not meet the requirementsof this specification, the tests(s) shall be conducted again onlyby agreement between the purchaser and seller. Under suchagreement, minimum requirements shall not be lowered,changed, or modified, nor shall specification limits be changed.If upon retest, failure occur
