Applicant's summary and conclusion
- Interpretation of results:
- other:
- Remarks:
- Negative results in skin irritation studies in animals and no positive results in humans result in non classification for irritancy and corrosion.In accordance with 31st Adaptation to Technical Progress (ATP) of Directive 67/548/ECC
- Conclusions:
- The test article could not be classified as irritant
- Executive summary:
There is no reason to classify this material as irritant nor corrosive.
This was confirmed with 31st Adaptation to Technical Progress (ATP) of Directive 67/548/ECC as published 15th January 2009 as the classification as “irritant” was removed for all types of man made vitreous fibres (MMVFs). .
