Significance and Use
4.1 The purpose of this classification system is to provide a method of adequately identifying polyethylene terephthlate films and sheeting and to provide a means for specifying these films and sheeting by the use of a simple line call-out designation.
1.1 This standard provides a classification system for tabulating the properties for biaxially oriented polyethylene terephthalate film and sheeting in thicknesses from 1.5 μm to 355 μm. For this classification system, polyethylene terephthalate film and sheeting shall be defined as the material derived from terephthalic acid and ethylene glycol and shall consist of at least 90 % polyethylene terephthalate homopolymer with a typical melting temperature range of 225 °C to 250 °C. This specification does not apply to coated, coextruded, tinted, pigmented, or metallized film or sheeting. This classification (in accordance with ) is intended to eventually replace Specification (ref. ).
Note 1: Film is defined in Terminology as an optional term for sheeting having a nominal thickness no greater than 250 µm.
Note 2: In order to conform to the original scope of Specification , this classification also includes sheeting up to and including thicknesses of 355 µm.
Note 3: It is strongly recommended that this classification system be used for all new applications and specifications and that the specification of films referencing Specification be expeditiously withdrawn or converted to this classification system.
1.2 Polyethylene terephthalate materials, being thermoplastic, are reprocessable and recyclable. This specification allows for the use of those polyethylene terephthalate plastic materials, provided that any specific requirements as governed by the producer and end user are met.
1.3 In all cases where the provisions of this classification system would conflict with a currently referenced ASTM specification for a particular film product, the latter shall take precedence (see ).
1.4 This classification system applies to commercial products and, as such, there is no control over the manufacturing parameters employed in producing the film. It shall be the responsibility of those developing the specification documents utilizing this classification system to identify the critical parameters and values to be used for the cell classifications and suffix requirements.
1.5 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.6 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
Note 4: There is no known ISO equivalent to this standard.
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
