1. SCOPE

1.1 This standard establishes a designation system for post-consumer poly (ethylene terephthalate) (PET) bottle recyclates, which may be used as the basis for specifications.

1.2 The types of PET bottle recyclate are differentiated from each other by a classification system based on appropriate levels of the following designatory properties:

a) intrinsic viscosity (IV);

b) levels of contamination due to the label and other visible contaminants, PVC and polyolfins(and including adhesive);

c) water content; and

d) bulk density.

Information regarding the intended application or method of processing will also assist in classification.

1.3 This standard is applicable to all PET bottle recyclates. It applies to material ready for normal use in the form of powder, flakes or pellets.

1.4 It is not intended to imply that materials having the same designation will give the same performance. This part of standard does not provide engineering data or data on processing conditions which might be required to specify a material for a particular application and/or method of processing. If such additional details are required, they shall be determined in accordance with the test methods specified in Part 2 of this standard, if suitable.

1.5 In order to specify a thermoplastic material for a particular application or to ensure reproducible processing, additional requirements may be given in data block 5 (see 3.1)
