This test method covers a gas chromatographic procedure for the determination of the ppm residual acetaldehyde (AA) present in poly(ethylene terephthalate) (PET) homopolymers and co-polymers which are used in the manufacture of beverage bottles. This includes sample types of both amorphous and solid-stated pellet and preform samples, as opposed to the bottle test, Test Method D 4509, an acetaldehyde test requiring 24 h of desorption time at 23°C into the bottle headspace and then the concentration of the headspace quantified by a similar GC method.
