ASTM D7082-21

Standard Specification for Polyethylene Stay In Place Form System for End Walls for Drainage Pipe

ABSTRACT
This specification addresses the requirements for polyethylene stay in place forms for end walls or head walls for use with standard storm drainage systems. The wall form system consists of a base wall form, a cap, an optional riser to adjust the height of the wall above the pipe, and an optional adaptor to adjust the pipe opening to accommodate smaller pipe sizes. The form system is manufactured using the rotational molding process and is available in different colors. The plastic shall be tested for its deflection temperature, flexural properties, melt flow rate, and density.
SCOPE
1.1 This specification addresses the requirements for polyethylene stay in place forms for end walls or head walls for use with standard storm drainage systems.  
1.2 The wall form system consists of a base wall form, a cap, an optional riser to adjust the height of the wall above the pipe, and an optional adaptor to adjust the pipe opening to accommodate smaller pipe sizes.  
1.3 The form system is manufactured using the rotational molding process and is available in different colors.  
1.4 The values stated in SI units are to be regarded as the standard, the inch-pounds in parentheses are given for information only.  
1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
Note 1: There is no known ISO equivalent to this standard.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
