Scope

This Standard specifies the terms and definitions, product classification, requirements,
test methods, inspection rules, marking and accompanying documents, packaging,
transportation and storage for poly (ethylene terephthalate) (PET) resin for bottles.
This Standard applies to homopolymer PET resin that uses purified terephthalic acid
and ethylene glycol as the main raw materials, and is produced by direct esterification
continuous polycondensation or intermittent polycondensation AND copolymer PET
resin that uses purified terephthalic acid, ethylene glycol and isophthalic acid as the
main raw materials and adopts direct esterification continuous polycondensation or
intermittent polycondensation to produce.
