ASTM D7082-21 PDF Download

The ASTM D7082-21 standard outlines the requirements for polyethylene stay in place forms used for end walls or head walls in standard storm drainage systems. These forms are designed to provide support and protection to the drainage pipe system.

The wall form system described in the standard includes a base wall form, a cap, and optional components such as a riser to adjust the height of the wall above the pipe and an adaptor to accommodate smaller pipe sizes. These components are manufactured using the rotational molding process, which ensures a durable and uniform product.

The standard also mentions that the form system is available in different colors, allowing for customization and easy identification during installation. Additionally, the plastic used in the manufacturing of the forms is required to undergo various tests, including deflection temperature, flexural properties, melt flow rate, and density, to ensure its quality and performance.
