Anotace 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.

1.1 This specification covers requirements for extruded (cast or blown) and compression-molded sheeting made from low-, medium- and high-density polyethylenes and copolymers in thickness of 0.25 mm (0.010 in.) and greater. 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. 1.2 Polyethylene materials, being thermoplastics, are reprocessable and recyclable (see Guides D5033 and D7209). This specification allows for the use of those polyethylene plastic materials, provided that any specific requirements as governed by the producer and end user are met. 1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only. 1.4 The following precautionary caveat pertains only to the test methods portion, Section 11, of this specification: Note 1: There is no known ISO equivalent to this standard. |
