Key value for chemical safety assessment

Additional information

The provision for further testing and simulation testing for biotic degradation is contained within Column 1 of Section 9.2 of Annexes VII and IX of REACH. Column 2 of Section 9.2 each of these Annexes, describing the Specific Rules for Adaptation from Column 1, clarifies the requirement for testing and choice of test, and states:

"Further biotic degradation testing shall be proposed by the registrant if the chemical safety assessment according to Annex I indicates the need to investigate further the degradation of a substance and its degradation products. The choice of appropriate test(s) depends on the results of the chemical safety assessment".

The Registration substance (EC-202-228-8) is a monomer imported in a polymer and does not require full chemical safety assessment (comprising hazard assessment, exposure assessment, and risk characterisation) under REACH. Ipso facto, in accordance with the Standard Information Requirements laid down by REACH (Annexes VII to X), further biotic degradation testing is not necessary.
