78.  For each test— N.I.

(a) a new test specimen shall be used;

(b) the rules prescribed for simulant D in Parts 3, 4 and 5 shall be applied for each test medium;

(c) subject to paragraph 4, compliance with a migration limit shall be determined by selecting the highest value using all the test methods.

Conventional conditions for substitute tests

Test conditions with simulant D	Test conditions with isooctane	Test conditions with ethanol 95%	Test conditions with MPPO(1)
(1) MPPO = Modified polyphenylene oxide
(2) The volatile test media are used up to a maximum temperature of 60°C. A precondition of using these tests is that the material or article will withstand the test conditions that would otherwise be used with simulant D. Immerse a test specimen in olive oil under the appropriate conditions. If the physical properties are changed (eg melting, deformation) then the material is considered unsuitable for use at that temperature. If the physical properties are not changed then proceed with the substitute tests using new specimens.

PART 7 N.I. Alternative Fat Tests for Overall and Specific Migration

82.  Subject to paragraph 2 the conditions which must be fulfilled to allow the result of either test specified in paragraph 3 to be used as an alternative to the result of a migration test carried out under Part 3 are that— N.I.

(a) the result obtained in a “comparison test” shows that the values are equal to or greater than those obtained in the test with simulant D; and

(b) the migration occurring in either test specified in paragraph 3 does not, after application of the appropriate reduction factor, exceed the appropriate migration limit.

83.  The condition in sub-paragraph (a) of paragraph 1 does not have to be fulfilled if it can be shown on the basis of the result of scientific experiment that the values obtained in either of the tests specified in paragraph 3 are equal to or greater than those obtained in any of the migration tests specified in Part 3. N.I.

I38 Sch. 3 para. 83 in operation at 5.5.2008, see reg. 1(b)

84.  The migration tests referred to in paragraphs 2 and 3 are — N.I.

(a) a test carried out using volatile media including isooctane, ethanol 95%, other volatile solvents or a mixture of solvents at such contact conditions as would result in values equal to or greater than those obtained in a test using simulant D;

(b) other tests using media having a very strong extraction power under very severe test conditions where, on the basis of scientific evidence, it is generally recognised that the results using these tests are equal to or higher than those obtained in a test using simulant D.
