Special provisions relating to overall migration

7.—( 1) Where a plastic material or article is intended to come into repeated contact with food and it is technically impossible to carry out the test described in paragraph 5, the test must be so modified as to enable the level of migration occurring during the third such test to be determined and, subject to sub-paragraph (2), such a determination may be used to prove excess of an overall migration limit in relation to a plastic material or article.

(2) Three identical samples of the plastic material or article are to be procured, following which—

(a) the first sample is to be subjected to the appropriate test according with paragraph 4 above and the overall migration determined (M1);

(b) the second and third samples are to be subjected to the same conditions of temperature but the period of contact had been two and three times that specified and overall migration had been determined in each case (M2 and M3).

(3) Where a modified test has been carried out in accordance with sub-paragraph (2), provided that either M1 or M3 — M2 did not exceed that overall migration limit, the plastic material or article subject to that test is deemed to be in compliant with that limit.
