Book excerpt: This document specifies the terms and definitions, basic requirements, selection of food simulants, selection of migration testing conditions, screening methods, chemical solvent substitution test, migration testing result correction and migration testing result selection of various food contact materials and products. 2 Terms and definitions 2.1 Migration testing Migration testing refers to a test conducted under specified conditions to determine the amount of migration of components of food contact materials and products into test medium such as food or food simulants in contact with them. Migration testing includes specific migration testing, total migration testing and chemical solvent substitution test. 2.2 Food simulant Food simulant is a test medium used to simulate food for migration testing. It can closely reflect the migration of components in food contact materials and products into the food in contact with them, and has the typical common characteristics of certain types of food. 2.3 Screening method It is a method that uses the amount used, total migration amount or residue amount to screen for specific migration (total) amount, so as to verify the compliance of a specific migration (total) amount of a certain (category) substance in food contact materials and products. 2.4 Chemical solvent substitution test A migration testing conducted under specified conditions using chemical solvents to replace oily food simulants. 2.5 Reusable food contact materials and products Food contact materials and products that have been or are expected to be used multiple times and come into repeated contact with food.
