GB/T 25255-2010 "Optical functional films - Polyethylene terephthalate（PET）film - Determination of tensile properties"

This standard specifies methods for determining the tensile performance of polyethylene terephthalate (PET) films in functional films for optical inspection. Including specimen preparation, tensile test equipment requirements, test procedures and data processing. By accurately measuring the strength, ductility and fracture characteristics of PET films during stretching, evaluate their Mechanical Properties and Reliability in practical applications to ensure that the films meet the requirements of use and mass standards.
