Abstract

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.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

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 D 5033 and D 7209 ). 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: 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 and health practices and determine the applicability of regulatory limitations prior to use.

Note 1There is no known ISO equivalent to this standard.
