Standard Specification for Poly(Vinyl Chloride) (PVC) Plastic Pipe Fittings, Schedule 40
|Publication Date:||1 May 2005|
|ICS Code (Plastics fittings):||23.040.45|
This specification covers poly(vinyl chloride) (PVC) Schedule 40 pipe fittings. Included are requirements for materials, workmanship, dimensions, and burst pressure.
NOTE 1 - Socket-type CPVC plastic pipe fittings, Schedule 40, which were formerly included in this standard, are now covered by Specification F 438.
The products covered by this specification are intended for use with the distribution of pressurized liquids only, which are chemically compatible with the piping materials. Due to inherent hazards associated with testing components and systems with compressed air or other compressed gases, some manufacturers do not allow pneumatic testing of their products. Consult with specific product/component manufacturers for their specific testing procedures prior to pneumatic testing.
NOTE 2 - Pressurized (compressed) air or other compressed gases contain large amounts of stored energy which present serious saftey hazards should a system fail for any reason.
Fitting such as unions, flanges, special plastic-to-metal transitions and appurtenances intended for use with PVC piping are covered under specification F 1970.
The text of this specification references notes, footnotes, and appendixes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the specification.
The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information only.
The following safety hazards caveat pertains only to the test method portion, Section 7, of this specification. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
