ASTM D4801-95(2001)e1
(Specification)Standard Specification for Polyethylene Sheeting in Thickness of 0.25 mm (0.010 in.) and Greater
Standard Specification for Polyethylene Sheeting in Thickness of 0.25 mm (0.010 in.) and Greater
SCOPE
1.1 This specification covers requirements for extruded- 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. Sheeting conforming to this specification is intended for use in the thinner gages principally for chemical tank linings, spacers in electrical equipment, and for thermoforming into such items as trays, pallets, and shipping containers. The thicker gages are used principally as machine-shop stock.
1.2 Polyethylene materials, being thermoplastics, are reprocessable and recyclable (see Guide D5033). 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 the 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 1-There is no similar or equivalent ISO standard.
