【国外标准】 Standard Specification for “Fiberglass” (Glass-Fiber-Reinforced Thermosetting-Resin) Sewer Pipe

This specification covers machine-made glass-fiber-reinforced thermosetting-resin (fiberglass) pipes such as reinforced thermosetting-resin pipe (RTRP) and reinforced polymer mortar pipe (RPMP; natural polymers not included) for use in gravity-flow systems for conveying sanitary sewage, storm water, and some industrial wastes. Material covered is of various type (RPMP/RTRP polyester or epoxy), liners (reinforced or non-reinforced thermoset liner, thermoplastic liner, or none), grades (polyester resin surface layer-reinforced or non-reinforced, polyester resin and sand surface layer-non-reinforced, epoxy resin surface layer-reinforced or non-reinforced, or none), and pipe stiffness. The pipe shall be manufactured as a composite structure consisting of resin, reinforcements, colorants, fillers, and other materials, free from all defects such as indentations, delaminations, bubbles, pinholes, cracks, pits, blisters, foreign inclusions, and resin-starved areas that are detrimental to the strength and serviceability of the pipe. The pipe shall also be uniform in color, opacity, density, and other physical properties, with the inside surface of the pipe free of bulges, dents, ridges, and other defects. The pipes shall be joined together using a joining system that will provide for fluid tightness in conformity with the service requirement and with the pipe joint surfaces free of dents, gouges, and other surface irregularities. Compression, tension, and long-term chemical tests as well as tests for dimensions, stiffness, and joint tightness shall be performed and shall conform to the requirements specified.1.1 This specification covers machine-made fiberglass pipe, 8 in. (200 mm) through 156 in. (4000 mm), intended for use in gravity-flow systems for conveying sanitary sewage, storm water, and some industrial wastes. 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 Although this specification is suited primarily for pipes to be installed in buried applications, it is acceptable to apply it to the extent applicable for other installations such as, but not limited to, jacking, tunnel lining and sliplining rehabilitation of existing pipelines.NOTE 2: There is no known ISO equivalent to this standard.1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.1.4 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.1.5 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.
