This topic provides a brief overview of the typical “base-set” of testing needed to provide classification and labelling end points and to enable a reasonable risk assessment to be constructed under Regulation No. 1907/2006/EC on the Registration, Evaluation and Authorisation of Chemicals (REACH).

Before considering the individual test methods, it is necessary to look at the studies in context of the “intelligent testing strategy” that describes the order in which the testing should be performed. Although each test is described separately, the results of one study can have a major impact on planning the next test; this is an essential part of constructing the intelligent testing strategy and such strategy is described in guidance provided by the European Chemicals Agency (ECHA). This means that the temptation to place all studies in one go without waiting for the result of initial work should be resisted.
