The ASTM F 2013-10 (2023) standard provides a method for the determination of acetaldehyde residues in polyethylene terephthalate (PET) bottles using an automated static headspace sampling device and a capillary tubing Gas Chromatograph with flame ionization Detector. This test method is mainly used for quality control in molding or synthesis operations, as acetaldehyde is a volatile degradation product during PET melt processing, which may affect the taste of food and beverages. This standard applies to the determination of acetaldehyde concentration in PET homopolymers and copolymers, and specifies sample desorption conditions and gas phase Chromatography procedures. It does not cover all safety issues, and users need to take appropriate safety measures themselves.
