Materials and methods

Principles of method if other than guideline:

The potential of the UVCB substance to be eye irritant was established by classifying the complex metal substance based on Mixture rules from EU CLP (summation and/or additivity of classified components to derive Hazard class). The classification criteria (as set out in EU CLP Guidance Annex I: 3.3.2.2 pg 247) can be used to estimate effects.

GLP compliance:

no

Remarks:

Test material

Test material information

Constituent 1

Reference substance name:

sulfuric acid hydrate

EC Number:

922-670-1

IUPAC Name:

sulfuric acid hydrate

Details on test material:

Worst case (max across industry) as in iuclid section 1.2;
see IUCLID Section 1.4, for company specific elemental composition; and representative sample for mineralogical information (IUCLID Section 4.23 -Outotec report)

Results and discussion

Any other information on results incl. tables

The calculated classification via Additivity method resulted in "serious eye damage / eye irritation: category 1A H314”, driven by H2SO4

Applicant's summary and conclusion

Interpretation of results:

Category 1 (irreversible effects on the eye)

Remarks:

Migrated information Criteria used for interpretation of results: EU

Conclusions:

Result can be used to predict hazard effect of the UVCB , and to classify it

Executive summary:

The study provided a Worst case estimate of the Eye Irritation/serious eye damage classification, derived on basis of the Classification outcome (Mixture toxicity rules) from a Worst case (maximum across industry) as defined in IUCLID section 1.2/1.4/4.23. The result is applicable to all Sulphuric acid, waste gas cooling and cleaning , copper smelting that fall under the defined concentration ranges (IUCLID section 1.2).
