Scope

1.1 This test method covers measurement of the deflection as a function of time of a specimen of fiberglass pipe supported on a flat non-arced support as a simple beam under full bore flow of water at elevated temperatures. Both glass-fiberreinforced thermosetting-resin pipe (RTRP) and glass-fiberreinforced polymer mortar pipe (RPMP) are fiberglass pipes. NOTE 1—For the purposes of this standard, polymer does not include natural polymers. 1.2 This test method can be used to determine deflection at varying conditions by substituting other test media. 1.3 Deflections observed using this test method are representative only of piping supported as a simple beam under full bore flow which has one diameter of pipe overhanging at each support. 1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information purposes only. NOTE 2—There is no known ISO equivalent to this standard. 1.5 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. 1.6 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.
