1、Designation: D 7082 04Standard Specification forPolyethylene Stay In Place Form System for End Walls forDrainage Pipe1This standard is issued under the fixed designation D 7082; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the y

2、ear of last revision. 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 addresses the requirements for poly-ethylene stay in place forms for end walls or head wall

3、s 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 manufactured using t

4、he 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 with its use. I

5、t 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 similar or equivalent ISO standard.2.
