1、Designation: D7082 04 (Reapproved 2010)Standard Specification forPolyethylene Stay In Place Form System for End Walls forDrainage Pipe1This standard is issued under the fixed designation D7082; the number immediately following the designation indicates the year oforiginal adoption or, in the case of
2、 revision, the year of last revision. 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 specification addresses the requirements for poly-ethylene stay in place forms for end wal
3、ls or head walls for usewith standard storm drainage systems.1.2 The wall form system consists of a base wall form, acap, an optional riser to adjust the height of the wall above thepipe, and an optional adaptor to adjust the pipe opening toaccommodate smaller pipe sizes.1.3 The form system is manuf
4、actured using the rotationalmolding process and is available in different colors.1.4 The values stated in SI units are to be regarded as thestandard, the inch-pounds in brackets are given for informationonly.1.5 This standard does not purport to address all of thesafety concerns, if any, associated
5、with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory requirements prior to use.NOTE 1There is no known ISO equivalent to this standard.2.
