This standard specifies the determination method of migration of vinyl acetate in food contact materials and articles.
This standard is applicable to the determination of migration of vinyl acetate in food contact materials and articles.
2 Principle
Leach the vinyl acetate in the specimen with food simulant soak solution, scale the volume with acetone, and finally carry out the gas chromatographic determination and the quantative determination by external standard method. Once detected, the sample shall be confirmed by gas chromatography-mass spectrometry.
3 Reagents and Materials
Unless otherwise specified, analytically-pure reagents and Class-I water (defined in GB/T 6682) are adopted for the purpose of this method. Containers and transfer appliances in test shall not be made of plastic materials.
3.1 Reagents
3.1.1 Acetone (C3H6O): free of vinyl acetate.
3.1.2 Methanol (C2H4O).
