1.1 This specification covers machine-made reinforced thermosetting resin pressure pipe (RTRP) manufactured by the filament winding process up to 24 in. nominal size. Included are a classification system and requirements for materials, mechanical properties, dimensions, performance, methods of test, and marking.

1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are provided for information purposes only.

1.3 The following safety hazards caveat pertains only to the test method portion, Section 8, of this specification: This standard does not purport to address all of the safety problems, 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 1—The term "fiberglass pipe" as described in Section 3 of this specification applies to both reinforced thermosetting resin pipe (RTRP) and reinforced plastic mortar pipe (RPMP). This specification covers only reinforced thermosetting resin pipe (RTRP).

Note 2—This specification is applicable to RTRP where the ratio of outside diameter to wall thickness is 10:1 or more.

Note 3—There is no similar or equivalent ISO Standard.

Note 4—For the purposes of this standard, polymer does not include natural polymers.
