2、n. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers requirements and test methodsfor materials, dimensions, workmanship, elongation, impactresistance, pipe
3、 stiffness, perforations, and markings for steelreinforced corrugated polyethylene (PE) piping systems ofnominal sizes 8 in. (200 mm), through 80 in. (2000 mm). Thesteel reinforced polyethylene pipes governed by this standardare intended for use in underground applications where soilprovides support
4、 for their flexible walls. These pipes will beused to collect or convey stormwater runoff for storm sewersand drainage pipes, or both.1.2 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided for
5、 information onlyand are not considered standard.1.3 There is no similar or equivalent ISO standard.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and heal
