ASTM D4801-08(2016)

Anotácia textu normy ASTM D4801-08(2016) :

This specification covers the requirements for extruded (cast or blown) and compression-molded sheeting made from low-, medium-, and high-density polyethylenes and copolymers in specified thicknesses. Depending on the functional requirements, sheeting conforming to this specification is used in applications such as chemical tank linings, spacers in electrical equipment, thermoforming into such items as trays, pallets, and shipping containers, and as machine-shop stock. This specification allows for reprocessable and recyclable polyethylene plastic materials, provided that any specific requirements as governed by the producer and end user are met. The three types of polyethylene sheeting covered here are: Type I, natural or colored for general purpose; Type II, natural or colored for dielectrics; and Type III, black for weather-resistant applications. Sampled specimens shall be tested for their conformance with physical requirements as follows: dimension (length, width, diameter, and cores); form; tensile strength at yield and nominal strain at break; shrinkage; warpage and twist; and color, appearance, and workmanship.
