1、Designation: D 5047 05Standard Specification forPolyethylene Terephthalate Film and Sheeting1This standard is issued under the fixed designation D 5047; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A n
2、umber in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers requirements for biaxiallyoriented polyethylene terephthalate film and sheeting in thick-nesses from 1.5 m 0
3、.06 mil to 35.5 m 14.0 mil. For thisspecification, polyethylene terephthalate film and sheetingshall be defined as the material derived from terephthalic acidand ethylene glycol and shall consist of at least 90 % polyeth-ylene terephthalate homopolymer. This specification does notapply to coated, co
4、extruded, tinted, pigmented, or metallizedfilm or sheeting.1.2 Polyethylene terephthalate materials, being thermoplas-tic, are reprocessable and recyclable.2This specification allowsfor the use of those polyethylene terephthalate plastic materi-als, provided that any specific requirements as governe
5、d by theproducer and end user are met.1.3 The values stated in SI units are to be regarded as thestandard.
