【国外标准】 Standard Specification for 3 to 30 in. (75 To 750 mm) Polypropylene (PP) Corrugated Single Wall Pipe and Fittings

This specification covers the general requirements and test methods for materials, dimensions, workmanship, elongation, brittleness, pipe stiffness, and markings for single wall corrugated polypropylene (PP) pipe and fittings used in non-pressure gravity applications, including leach field effluent disposal, and drainage applications such as land, roads, foundations, agricultural, and landfill. It applies to PP corrugated single wall pipe and fittings with nominal sizes 3 in. through 30 in. (75 mm through 750 mm). This specification includes minimum properties for PP compounds used in the manufacture of corrugated single wall pipes, as well as nominal pipe sizes, inside diameters and tolerances for single wall corrugated PP pipes. It also covers fittings and joining system requirements, installation requirements, sampling and retest, certification, reporting, packaging, and quality assurance.1.1 This specification covers requirements and test methods for materials, dimensions, workmanship, elongation, brittleness, pipe stiffness, and markings for single wall corrugated polypropylene (PP) pipe and fittings. It covers nominal sizes 3 in. through 30 in. (75 mm through 750 mm)1.2 The corrugated polypropylene pipe and fittings are for use in non-pressure applications where soil-tight joints are acceptable, such as leach field effluent disposal, and drainage applications such as land, roads, foundations, agricultural, and landfill. Products meeting this specification are not suitable for applications requiring water-tight joints unless the manufacturer offers such joints as an option.NOTE 1: Watertight joints, when requested or specified, should meet a 10.8 psi (74 kPa) laboratory internal and external pressure in accordance with Specification D3212 and should utilize a bell and spigot design with a gasket that complies with Specification F477.1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered 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 the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.5 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.
