1.1 This specification covers requirements for biaxially oriented polyethylene terephthalate film and sheeting in thicknesses from 1.5 [mu]m (0.06 mil) to 35.5 [mu]m (14.0 mil). For this specification polyethylene terephthalate film and sheeting shall be defined as the material derived from terephthalate acid and ethylene glycol and shall consist of at least 90% polyethylene terephthalate homopolymer. This specification does not apply to coated, coextruded, tinted, pigmented, or metallized film or sheeting.
