Article 7
Testing of surfactants All tests referred to in Articles 3 and 4 and in Annexes II, III, IV and VIII shall be conducted in compliance with the standards mentioned in Annex I.1 and in accordance with testing requirements under Article 10(5) of Regulation (EEC) No 793/93. For this purpose, it is sufficient to apply either the EN ISO/IEC standard or the principles of good laboratory practice, except for those tests for which the principles of good laboratory practice have been made mandatory. In cases where surfactants are used in detergents which were placed on the market before the entry into force of the above standard, existing tests that were performed using the best scientific knowledge available, and that were performed to a standard comparable to those of the standards mentioned in Annex I may be accepted on a case-by-case basis. The manufacturer or the Member State may submit to the Commission any case over which there is doubt or dispute. A decision shall then be taken in accordance with the procedure laid down in Article 12(2).
