Scope*1.1 This specification covers p
3、oly(vinyl chloride) (PVC) Schedule 40 pipe fittings. Included are requirements for materials,workmanship, dimensions, and burst pressure.NOTE 1Socket-type CPVC plastic pipe fittings, Schedule 40, which were formerly included in this standard, are now covered by Specification F438.1.2 The products co
4、vered by this specification are intended for use with the distribution of pressurized 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
5、 allow pneumatic testing of their products. Consult withspecific product/component manufacturers for their specific testing procedures prior to pneumatic testing.NOTE 2Pressurized (compressed) air or other compressed gases contain large amounts of stored energy which present serious saftey hazards s
6、houlda system fail for any reason.1.3 Fitting such as unions, flanges, special plastic-to-metal transitions and appurtenances intended for use with PVC piping arecovered under specification F1970.1.4 The text of this specification references notes, footnotes, and appendixes which provide explanatory
7、 material. These notesand footnotes (excluding those in tables and figures) shall not be considered as requirements of the specification.1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematicalconversions to SI units that are provided
8、 for information only and are not considered standard.1.6 The following safety hazards caveat pertains only to the test method portion, Section 7, of this specification.This standarddoes not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of t
9、he user of thisstandard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.2.
