10、ct with foodstuffs 3, and the subsequent amendments (Directives 93/8/EEC 4 and 97/48/EC 5), recognizes that there are difficulties in the determination of the migration in food products and allows use of food simulants with conventional test conditions, which reproduce, as far as possible, the migra
11、tion phenomena which may occur with contact between the article and foodstuffs. There are four food simulants: - simulant A, distilled water or water of equivalent quality; - simulant B, 3% acetic acid (w/v) in aqueous solution; - simulant C, 10% ethanol (v/v) in aqueous solution; - simulant D, rect
12、ified olive oil, or other fatty food simulants. European Directive 82/711/EEC and the subsequent amendments also contain the conventional test conditions (time and temperature) for migration tests with food simulants. European Commission Directive 97/48/EC, the second amendment to European Council D
13、irective 82/711/EEC, also contains test media and conventional test conditions for substitute tests. Substitute tests may be performed in place of migration tests with simulant D, if it has been shown that for technical reasons connected with the method of analysis it is not feasible to obtain a val

15、I EN 1186-7:2002 (E) 14 plastics materials and articles intended to come into contact with foodstuffs 6 has a Table in the Annex which contains a non-exhaustive list of foodstuffs and which identify the simulants to be used in migration tests on those plastic materials and articles intended to come
16、into contact with a particular foodstuff or group of foodstuffs. This standard contains the test methods for the measurement of overall migration from plastics materials to food simulants, or test media, using conventional contact test conditions of time and temperature, to determine compliance with
17、 the legislative overall migration limit specified in article 2 of European Commission Directive 90/128/EEC. These test methods may also be used for the verification of compliance with the specific migration limits provided for in paragraph 1 of Commission Directive 90/128/EEC, if it can be establis
18、hed that compliance with the overall migration limit laid down in Article 2 of Commission Directive 90/128/EEC implies that the specific migration limits are not exceeded. Commission Directive also specifies that the migration tests using rectified olive oil or substitutes shall not be carried out t
