This specification covers machine-made reinforced thermosetting resin pressure pipe (RTRP) manufactured by the filament winding process. This specification does not include reinforced polymer mortar pipe (RPMP), which is another type of fiberglass pipe. The pipes are generally classified by type, grade, class, and hydrostatic design. In addition, a secondary cell classification system defines the basic mechanical properties of the pipe. The resins, reinforcements, colorants, fillers, and other materials, when combined as a composite structure, shall produce a pipe that shall meet the performance requirements of this specification. Materials shall be tested and the individual grades shall conform to the specified values of dimensions and tolerances, long-term static hydrostatic strength, long-term cyclic hydrostatic strength, short-term hydrostatic failure strength, longitudinal tensile properties, and stiffness factor.

1.1 Thisspecification covers machine-made reinforced thermosetting resinpressure pipe (RTRP) manufactured by the filament winding processup to 60 in. nominal size. Included are a classification system andrequirements for materials, mechanical properties, dimensions,performance, methods of test, and marking.

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

1.3The following safety hazards caveat pertainsonly to the test method portion, Section 8, of this specification: This standard does not purport to address all ofthe safety problems, if any, associated with its use. It is theresponsibility of the user of this standard to establishappropriate safety and health practices and determine theapplicability of regulatory limitations prior touse.

Note1: The term “fiberglass pipe” asdescribed in Section 3 ofthis specification applies to both reinforced thermosetting resinpipe (RTRP) and reinforced polymer mortar pipe (RPMP). Thisspecification covers only reinforced thermosetting resin pipe(RTRP).

Note2: This specification is applicableto RTRP where the ratio of outside diameter to wall thickness is10:1 or more.

Note3: There is no known ISO equivalentto this standard.





Note4: For the purposes of thisstandard, polymer does not include natural polymers.

1.4This international standard was developed in accordance withinternationally recognized principles on standardizationestablished in the Decision on Principles for the Development ofInternational Standards, Guides and Recommendations issued by theWorld Trade Organization Technical Barriers to Trade (TBT)Committee.
