Materials and methods

Principles of method if other than guideline:
Reproductive potential of the UVCB potential was determined by classifying based on Mixture rules from EU CLP (additivity formula of classified components to derive hazard class). The classification criteria were used to estimate effects.

Applicant's summary and conclusion

Conclusions:
Good quality study with result derived on basis of the Classification outcome (Mixture toxicity rules) from the reasinable worst case sample of the substance (maximum of typicals across industry as defined in IUCLID section 1.2/1.4). The analysed UVCB sample is classified for reproductive toxicity.
Executive summary:

The study provided a conservative estimate, derived on basis of the classification outcome (mixture toxicity rules) from a reasonable worst-case sample of the substance using mineralogical information from the representative sample. 

 

Validity of the model used:

1. Defined endpoint: the endpoint is a REACH compliant defined endpoint

2. Unambiguous algorithm: EU CLP guidance based summation formula to determine classification, followed by back-calculation to related hazard criteria

3. Applicability domain: applicable to classify complex metal containing materials. 

4. Mechanistic interpretation - metal species: the tool translates the elemental composition into a mineralogical composition relevant for classification.
