Applicant's summary and conclusion

Interpretation of results:
not irritating
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
Strontium chromate should not be classified as irritating to the eyes.
Executive summary:

The potential of strontium chromate to induce eye irritation was testing in rabbits according to the OECD guideline test 405. Slight eye irritation was observed, but according to EC classification criteria, the test item should not be classified as irritating to the eyes.
