ICS 97.200.50

PCD 12

1 SCOPE

1.1 This standard prescribes the requirements and the methods of sampling and tests for polyethylene terephthalate (PET) and polybutylene terephthalate (PBT) materials for moulding and extrusion.

1.2 This standard is intended to be used for characterization of PET and PBT materials on the basis of basic polymer properties and recommended end-uses.

1.3 This standard is only applicable to virgin PET and PBT.
