Anotácia

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.
