Article 13(2) of Regulation (EC) No 1907/2006 provides that test methods used to generate information on intrinsic properties of substances required by that Regulation are to be regularly reviewed and improved with a view to reducing testing on vertebrate animals and the number of animals involved. When appropriate validated test methods become available, the Commission Regulation (EC) No 440/2008 and the Annexes to Regulation (EC) No 1907/2006 should be amended, if relevant, so as to replace, reduce or refine animal testing. The principles of replacement, reduction and refinement, enshrined in Directive 2010/63/EU of the European Parliament and of the Council should be taken into account.

Regulation (EC) No 1907/2006 establishes requirements for the registration of substances manufactured or imported in the Union on their own, in mixtures or articles. The registrants have to provide the information required by Regulation (EC) No 1907/2006, as appropriate, in order to fulfil the registration requirements.

Pursuant to Regulation (EC) No 1907/2006, in vivo studies are required for the generation of information on skin irritation and eye irritation in points 8.1 and 8.2 of Annex VIII to Regulation (EC) No 1907/2006.

In recent years, significant scientific progress has been made in the development of alternative test methods for skin corrosion/irritation and serious eye damage/eye irritation. A number of test guidelines for alternative test methods have been internationally agreed by the Organisation for Economic Cooperation and Development (OECD), and have been included in Regulation (EC) No 440/2008.

For skin corrosion/skin irritation, adequate information for the classification and risk assessment of a substance may be obtained in most cases solely on the basis of in vitro studies. A conclusion may be drawn on the basis of one in vitro test, if the result allows an immediate reliable decision on classification or non-classification, or from a combination of two in vitro tests, one for skin irritation and one for skin corrosion. In vivo studies may still be required in some exceptional cases for substances manufactured or imported in quantities of 10 tonnes or more, e.g. when the substance tested falls outside the applicability domain of the in vitro test methods or when no conclusive results can be obtained from a comprehensive set of in vitro tests.

For serious eye damage/eye irritation, a set of in vitro test methods exists which would be sufficient in many cases to obtain information adequate for classification and risk assessment of substances. A conclusion about the potential of a substance to cause such eye effects may be drawn on the basis of one test, if the result allows an immediate reliable decision on classification or non-classification, or from a combination of two or more tests. In vivo studies may still be required in some cases for substances manufactured or imported in quantities of 10 tonnes or more, e.g. when the substance tested falls outside the applicability domain of the test methods or when no conclusive results can be obtained from a comprehensive set of in vitro tests.

Points 8.1 and 8.2 of Annex VIII should thus be amended so that the standard information requirement should be for the in vitro studies while setting the conditions under which an in vivo study for skin irritation/corrosion and serious eye damage/eye irritation is still required. Nevertheless, adequate information from existing in vivo skin irritation or eye irritation studies can still be used to fulfil the information requirement at any tonnage level.

In addition, the standard information requirements and adaptation rules in points 8.1, and 8.2 of Annex VII, and the adaptation rules in points 8.1 and 8.2 of Annex VIII should be revised in order to remove redundancies with rules set by Annex VI and Annex XI and in the introductory parts of Annexes VII and VIII as regards the review of available data, the waiving of studies for a toxicological endpoint if the available information indicates that the substance meets the criteria for classification for that toxicological endpoint, or to clarify the intended meaning as regards the waiving of studies for substances that are flammable under certain conditions. Where reference is made to the classification of substances, adaptation rules should be updated to reflect the terminology used in Regulation (EC) No 1272/2008 of the European Parliament and of the Council.

For acute toxicity, in addition to a test via the oral route (Annex VII, point 8.5.1) point 8.5 of Annex VIII to Regulation (EC) No 1907/2006 provides a standard information requirement for substances other than gases by at least one additional route (inhalation or dermal) depending on the likely route of human exposure. Recent scientific analysis of available data from in vivo acute toxicity studies have shown that substances that are not toxic via the oral route may be expected with high certainty to be also non-toxic via the dermal route. Therefore, testing those substances via the dermal route does not provide essential information for their safety assessment. Point 8.5 of Annex VIII to Regulation (EC) No 1907/2006 should thus be amended to provide for the possibility to waive the dermal test for such substances.

ECHA, in cooperation with Member States and stakeholders, should further develop guidance documents for the application of the test methods and waiving possibilities for the standard information requirements provided by this Regulation for the purposes of Regulation (EC) No 1907/2006. In doing so, ECHA should take full account of the work carried out in OECD, as well as in other relevant scientific and expert groups.

Regulation (EC) No 1907/2006 should therefore be amended accordingly.

The measures provided for in this Regulation are in accordance with the opinion of the Committee established under Article 133 of Regulation (EC) No 1907/2006,
