Results
No significant variation between the temperature in the test substance and the oven temperature could be observed.
The test substanceMEXORYL SAG/10 lyophiliséis considered as not auto-flammable under the test conditions.
Applicant's summary and conclusion
- Conclusions:
- No significant variation between the temperature in the test substance and the oven tem-perature could be observed. The test substance MEXORYL SAG/10 lyophilisé is considered as not auto-flammable under the test conditions.
- Executive summary:
The relative self-ignition temperature of the test item has been investigated with a not-GLP compliant study following the EU method A.16. No significant variation between the temperature in the test substance and the oven temperature could be observed. The test item is considered as not auto-flammable under the test conditions.
