A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (´) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specif i cation covers requirements and test methodsfor materials, workmanship, dimensions, perforations, pipestiffness, elongation, joint separation resistance, quality ofextruded polyethylene, brittleness, testing, and marking ofcorrugated polyethylene (PE) pipe and f i ttings for mine heapleach pile aeration. It covers with nominal sizes 100 mm (4inch), 150 mm (6 inch), 200 mm (8 inch), 250 mm (10 inch)300 mm (12 inch), 375 mm (15 inch), and 450 mm (18 inch)diameter.1.2 This specif i cation covers double wall, annular extrudedcorrugated polyethylene pipe as depicted in Fig. 1.1.3 The values given in parentheses are provided for infor-mation purposes only.1.4 The following precautionary caveat pertains only to thetest method portion, Section 9, of this specif i cation: Thisstandard does not purport to address all of the safety concerns,if any, associated with its use. It is the responsibility of the userof this standard to establish appropriate safety and healthpractices and determine the applicability of regulatory limita-tions prior to use.2.
