Standard Practice for Separation and Identification of Poly(Vinyl Chloride) (PVC) Contamination in Poly(Ethylene Terephthalate) (PET) Flake
1.1 This practice covers four procedures for separation and qualitative identification of poly(vinyl chloride) (PVC) contamination in poly(ethylene terephthalate) (PET) flakes.
1.2 Procedure A is based on different fluorescence of PVC and PET when these polymers are exposed to ultraviolet (UV) light.
1.3 Procedure B is an oven test based upon the charring of PVC when it is heated in air at 235°C.
1.4 Procedures C and D are dye tests based on differential staining of PVC and PET.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazards see Section 8.
