Standard Specification for 6 to 30 in. (152 To 762 mm) Polypropylene (PP) Corrugated Single Wall Pipe And Double Wall Pipe
SCOPE
1.1 This specification covers requirements and test methods for materials, dimensions, workmanship, elongation, brittleness, pipe stiffness, perforations and markings for single wall corrugated polypropylene (PP) pipe and double wall corrugated polypropylene (PP) pipe. It covers nominal sizes 6 in. through 30 in. (152 mm through 762 mm).
1.2 The corrugated polypropylene pipes governed by this standard are intended for use in non-pressure applications for sanitary sewers, storm sewers and drainage pipes. Single wall corrugated polypropylene pipe shall not be used for sanitary sewer applications.
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 and health practices and determine the applicability of regulatory limitations prior to use.
