1.1 This specification covers the classification of polyethylene film and sheeting up to 0.3 mm (0.012 in.) in thickness, inclusive. The film or sheeting may contain additives for the improvement of the surface properties, pigments, or stabilizers, or combinations thereof. Note 1: Film is defined in Terminology D883 as an optional term for sheeting having a nominal thickness no greater than 0.254 mm (0.010 in.). 1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only. 1.3 The following precautionary caveat pertains only to the test method portion, Section 8 , 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. 1.4 This specification allows for the use of recycled polyethylene film or resin as feedstock, in whole or in part, as long as all the requirements as governed by the producer and end user are also met (see Note 2 ). Note 2: Guide D7209 describes terminology and definitions related to recycled plastics. Note 3: There is no known ISO equivalent to this standard.
