Materials and methods
Test guideline
- Qualifier:
- no guideline available
- Principles of method if other than guideline:
- The study report contains the limited information on the test conditions because the study has been performed in 1991. However available information is sufficient to conclude on the classification of the substance. Further the test was performed on the vertebrates and use of results from old experimental studies is one of the options to provide information requested by REACH. New experimental studies with vertebrates must only be conducted if there is no adequate existing information.
- GLP compliance:
- not specified
