- no flash point according to standard method
Any other information on results incl. tables
The test cup was heated at a rate of 5 ± 0.5°C/minute. Starting at 25°C, an attempt was made to ignite the vapour of the test item for every 2°C temperature rise. No flash-point was observed below the temperature at which reaction and/or degradation of the test item (i.e. 287°C) occurred. Therefore the preliminary test was repeated. The temperature of the test item at the start of the additional test was 25°C. Starting at 25°C the ignition source was applied for every 2°C temperature rise.
It was visually observed that the test item reacted and/or degraded at approximately 280°C. No flammable vapour/air mixture was produced at temperatures below the temperature at which reaction and/or degradation of the test item occurred. From this, it was concluded that the test item has no flash point.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The closed cup method was applied for the determination of the flash-point of the test substance. No flash-point was observed below the temperature at which reaction and/or degradation of the test item occurred.
