Extent: E+W+S+N.I.

Results obtained from valid qualitative or quantitative structure-activity relationship models ((Q)SARs) may indicate the presence or absence of a certain dangerous property. Results of (Q)SARs may be used instead of testing when the following conditions are met:
results are derived from a (Q)SAR model whose scientific validity has been established,
the substance falls within the applicability domain of the (Q)SAR model,
results are adequate for the purpose of classification and labelling and/or risk assessment, and
adequate and reliable documentation of the applied method is provided.
The Agency in collaboration with ... interested parties shall develop and provide guidance in assessing which (Q)SARs will meet these conditions and provide examples.
When nanoforms are covered by the registration the above approach shall address the nanoforms separately.
