1、Designation:D819518Standard Classification System and Basis for Specification forPolyethylene Terephthalate Film and Sheeting1This standard is issued under the fixed designation D8195;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,t
2、he year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This standard provides a classification system for tabu-lating the properties for biaxially oriented polyethylen
3、e te-rephthalate film and sheeting in thicknesses from 1.5 m to 355m.For this classification system,polyethylene terephthalatefilm and sheeting shall be defined as the material derived fromterephthalic acid and ethylene glycol and shall consist of atleast 90%polyethylene terephthalate homopolymer wi
4、th atypical melting temperature range of 225 C to 250 C.Thisspecification does not apply to coated,coextruded,tinted,pigmented,or metallized film or sheeting.This classification(in accordance with D8065/D8065M)is intended to eventuallyreplace Specification D5047(ref.Note 3).NOTE1Film is defined in T
5、erminology D883 as an optional term forsheeting having a nominal thickness no greater than 250 m.NOTE2In order to conform to the original scope of SpecificationD5047,this classification also includes sheeting up to and includingthicknesses of 355 m.NOTE3It is strongly recommended that this classific
6、ation system beused for all new applications and specifications and that the specificationof films referencing Specification D5047 be expeditiously withdrawn orconverted to this classification system.1.2 Polyethyleneterephthalatematerials,beingthermoplastic,are reprocessable and recyclable.This spec
7、ifi-cation allows for the use of those polyethylene terephthalateplastic materials,provided that any specific requirements asgoverned by the producer and end user are met.1.3 In all cases where the provisions of this classificationsystem would conflict with a currently referenced ASTMspecification f
8、or a particular film product,the latter shall takeprecedence(see Note 3).1.4 This classification system applies to commercial prod-ucts and,as such,there is no control over the manufacturingparameters employed in producing the film.It shall be theresponsibility of those developing the specification
