ABSTRACT 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. SCOPE 1.1 This specification covers machine-made reinforced thermosetting resin pressure pipe (RTRP) manufactured by the filament winding process up to 60 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 concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental 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 polymer mortar pipe (RPMP). This specification covers only reinforced thermosetting resin pipe (RTRP). Note 2: There is no known ISO equivalent to this standard. Note 3: This specification is applicable to RTRP where the ratio of outside diameter to wall thickness is 10:1 or more. Note 4: For the purposes of this standard, polymer does not include natural polymers. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
