IS 16630 : Part 1 : 2025 Plastic - Recyclates from Post-Consumer Bottles and Other Forms of Poly (Ethylene Terephthalate) (PET) - Part 1 Designation System and Basis for Specification
1 SCOPE
1.1 This standard (Part 1) establishes a designation system for recyclates produced from post-consumer poly (ethylene terephthalate) (PET) bottles and other forms (such as jars, thermoformed trays/cups, etc), which may be used as the basis for specifications.
1.2 This standard is applicable to all forms of 'recyclates' (flakes, pellets and powder) generated from the mechanical recycling processes and meant for non-food applications.
1.3 This standard deals with mechanical recycling processes provided for in IS 14534, pertaining specifically to those without the intentional addition of any chemicals/comonomers/modifiers during recyclate formation.
1.4 Due to the variations in the input (post-consumer PET) and in the recycling processes, the output (recyclates) may differ in various attributes, like contamination levels, properties, etc. Based on these attributes, the recyclates need to be segregated for their effective utilization subsequently. For example, in order to identify the various recyclates according to their attributes, a designation system that is in control of the recycler is proposed in this standard.
1.5 The designation system is merely an identification of the recyclates attributes. The designation system:
a) is not meant to suggest the recyclate' s fitness for purpose;
b) is not intended to imply that materials having the same designation will give the same performance; and
c) is merely a classification system to facilitate segregation of recyclates.
1.6 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 the standard, if applicable.
