1.1 This classification covers machine-made “fiberglass” (glass-fiber-reinforced thermosetting-resin) pressure pipe. Methods of classification, requirements, test methods and the method of marking are included. Both glass-fiber-reinforced thermosetting-resin pipe (RTRP) and glass-fiber-reinforced polymer mortar pipe (RPMP) are fiberglass pipes.
Note 1 – For the purposes of this standard, polymer does not include natural polymers.
1.2 This classification is based on the method of manufacture, the type of materials used in construction, and the test performance of the product type. It is not based on dimensions or raw material specifications.
1.3 Two methods of classifying long-term strength are included: (1) based on cyclic loads for use in those liquid-handling applications where the effects of pumping by duplex or triplex pumps or other cyclic pressure loads dictate the performance requirements of the piping, and (2) based on the steady (static) loads such as would be required for gas service applications.
1.4 The values stated in inch-pound units are to regarded as the standard. The values in parentheses are provided for information only.
1.5 The following precautionary caveat pertains only to the test method portion, Section 7, of this classification. 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.
Note 2 – There is no similar or equivalent ISO standard.
