This Test Guideline proposes defined approaches (DA) combining data generated in vitro methods, with information sources such as physicochemical properties. The prediction from a DA may be used alone to determine eye hazard potential according to the hazard classes of the UN GHS (Categories 1, 2, or not classified). A DA consists of a fixed data interpretation procedure (DIP) (i.e. a mathematical model, a rule-based approach) applied to data (e.g in silico predictions, in chemico, in vitro data) generated with a defined set of information sources to derive a prediction without the need for expert judgment. The DAs use method combinations intended to overcome some of the limitations of the individual, stand-alone methods in order to provide increased confidence in the overall obtained result.
