(Specification)Standard Specification for “Fiberglass” (Glass-Fiber-Reinforced Thermosetting-Resin) Pipe Fittings for Nonpressure Applications
Standard Specification for “Fiberglass” (Glass-Fiber-Reinforced Thermosetting-Resin) Pipe Fittings for Nonpressure Applications
ABSTRACT
This specification covers fiberglass pipe fittings intended for use in gravity flow systems for conveying sanitary sewage, storm water, and those industrial wastes for which the fittings are determined to be suitable. Laminating resins shall be classified as Types 1 and 2. Reinforcements shall be classified as Grades 1 and 2. Ultimate tensile strength; maximum shear strength; and dimension tests shall be performed to conform the requirements specified.
SCOPE
1.1 This specification covers fiberglass pipe fittings intended for use in gravity flow systems for conveying sanitary sewage, storm water, and those industrial wastes for which the fittings are determined to be suitable. Elbows, tees, laterals, crosses, reducers, and adapters 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 specification is intended to cover only dimensions, material properties, and workmanship rather than the structural design of the fittings. The structural design of the fittings shall be as agreed upon between purchaser and supplier, and needs to take into consideration the anticipated conditions of installation and service.
1.3 This specification covers only fittings fabricated from cut sections of pipe, or from a combination of pipe sections and contact molded (hand layup), or machine fabricated components.
1.4 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information purposes only.
1.5 The following safety hazards caveat pertains only to the test method portion, Section 11, 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 2: There is no known ISO equivalent to this standard.
1.6 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.
