Polyethylene terephthalate (PET) resin for bottles

This standard specifies the terms and definitions for bottle polyethylene terephthalate (PET) resin, product classification, requirements, test methods, inspection rules, signs and accompanying documents, packaging, transportation and storage.
This standard is applicable to homopolymerized PET resins produced by using pure terephthalic acid and ethylene glycol as the main raw materials, using direct esterification continuous polycondensation or batch polycondensation, and refined terephthalic acid, ethylene glycol and isophthalic acid As the main raw material, copolymerized PET resin produced by direct esterification continuous polycondensation or batch polycondensation is used.
