Significance and Use
This practice provides for determining the physical dimensions of fiberglass pipe and fittings. This practice is suitable for determination of dimensional compliance with product specifications.
1.1 This practice covers the determination of outside diameter, inside diameter, total wall thickness, reinforced wall thickness, liner thickness (where applicable), and length dimensions of “fiberglass” (glass-fiber-reinforced thermosetting resin) pipe. Included are procedures for measuring tapered dimensions and taper angles for pipe intended to be joined by tapered socket fittings, and procedures for gaging internal and external threads.
1.2 This practice also includes procedures for determining dimensions for fiberglass pipe fittings.
1.3 The values stated in inch-pound units are to be regarded as the standard. The SI units given in parentheses are for information only.
Note 1—There is no similar or equivalent ISO standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
