Annex XI in vitro methods Results obtained from suitable in vitro methods may indicate the presence of a certain dangerous property or may be important in relation to a mechanistic understanding, which may be important for the assessment. In this context, ‘suitable’ means sufficiently well developed according to internationally agreed test development criteria (e. g. the European Centre for the Validation of Alternative Methods (ECVAM)) criteria for the entry of a test into the prevalidation process). … If the results obtained from the use of such in vitro methods do not indicate a certain dangerous property, the relevant test shall nevertheless be carried out at the appropriate tonnage level to confirm the negative result, … Such confirmation may be waived, if the following conditions are met: (1) results are derived from an in vitro method whose scientific validity has been established by a validation study, according to internationally agreed validation principles; (2) results are adequate for the purpose of classification and labelling and/or risk assessment; and (3) adequate and reliable documentation of the applied method is provided.

Definition of hazard and risk

Hazard is the inherent property of an agent having the potential to cause adverse

effects in an organism exposed to the agent.

Risk is the probability of an adverse effect in an organism caused

under specified circumstances by exposure to an agent.
