1 Scope

This standard specifies the determination method of overall migration in food contact materials and articles.
This standard is applicable to the determination of overall migration in food contact materials and articles, instead of that in food simulants of vegetable oil type.

2 Theory

Soak the specimen with various food simulants, evaporate and dry the soak solution, and obtain the total amount of non-volatile matter migrated from the specimen to soak solution.

3 Reagents and Materials (Food Simulants)

Unless otherwise specified, all reactants adopted for this method are analytically pure and water is Grade 2 water as specified in GB/T 6682.
3.1 Reactants
3.1.1 Food simulants: operate according to GB 31604.1.
3.1.2 Trichloromethane (CHCl3).
3.2 Preparation of reagents
Preparation of food simulants: operate according to GB/T 5009.156.
