| Significance and Use | ||||||

5.1 This test method determines the long-term ring-bending strain of pipe when deflected under constant load and immersed in a chemical environment. It has been found that effects of chemical environments can be accelerated by strain induced by deflection. This information is useful and necessary for the design and application of buried fiberglass pipe. Note 3: Pipe of the same diameter but of different wall
thicknesses will develop different strains with the same
deflection. Also, pipes having the same wall thickness but
different constructions making up the wall may develop different
strains with the same deflection.

| 1. Scope | ||||||
|
1.1 This test method covers a procedure for determining the long-term ring-bending strain (Sb) of “fiberglass” pipe. Both glass-fiber-reinforced thermosetting-resin pipe (RTRP) and glass-fiber-reinforced polymer mortar pipe (RPMP) are “fiberglass” pipes. 1.2 The values stated in inch-pound units are to be regarded as the standard. The SI units given in parentheses are for information only. 1.3 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: There is no known ISO equivalent to this standard. 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. |
