ASTM F2720/F2720M-08

Standard Specification for Glass Fiber Reinforced Polyethylene (PE-GF) Spiral Wound Large Diameter Pipe

SCOPE
1.1 This specification covers requirements and test methods for materials, dimensions, workmanship, joining systems, and marking for large diameter, 12 in. [300 mm] and larger, inside diameter controlled glass fiber reinforced polyethylene (PE-GF) spiral wound pipe with electrofusion joints. The piping is intended for new construction and renewal of existing piping systems used for the transport of water, slurries, municipal sewage, domestic sewage, effluents, etc., in pressure systems.
Note 1—Pipe produced to this specification should be installed in accordance with Practice D 2774 or Guide F 1668, where applicable, and with the manufacturer’s recommendations.
1.2 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text the SI units are shown in brackets. The values stated in each system may not be exact equivalents: therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.3 All pipes produced under this specification are pressure-rated.
1.4 This specification includes criteria for choice of raw material and test methods for evaluation of raw material, together with performance requirements and test methods for determining conformance with the requirements.
1.5 In referee decisions, the SI units shall be used for metric-sized pipe and inch-pound units for pipe sized per ANSI (ANSI B 36.10).
1.6 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 and health practices and determine the applicability of regulatory limitations prior to use.
