Consequently products are out of industrial control for a period of time.
It is possible that during this period contamination with other materials may occur that could affect the product's suitability for recycling into the intended application.

This standard is applicable without prejudice to any existing legislation. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

The characteristics of PET recyclates, which shall be met for every batch (see ISO 3534-2) of PET recyclate are shown in Table 1, and are divided into two types:

 Optional characteristics needed to characterise PET recyclates according to customer specifications and applications. These characteristics shall be assessed by using the test methods given in Table 1 and detailed below.
A Certificate of Analysis, providing the test results for each batch of recyclate shall be provided by the supplier to the purchaser upon request.
To secure the legal use of the recyclate, the supplier shall provide the necessary information about the material composition of the recyclates, as specified by the purchaser. SAFETY PRECAUTIONS — WARNING: It is most important for safety reasons that personal protective clothing is used when applying solvents to the test specimen. The use of solvents in regard to application of this standard may be further controlled under National and/or regional legislation.
