Specific details on test material used for the study:

SOURCE OF TEST MATERIAL
- Source and lot/batch No.of test material: Lot # 20003, unit 0022
- Physical state: Clear colourless liquid
- Analytical purity: 99.7%
- Expiration date of the lot/batch: 30 March 2018

STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: at room temperature

Key result

Remarks on result:

no flash point up to 100°C

No flash-point was observed below 111 °C, the temperature at which the test item shows significant evaporation.

Interpretation of results:

GHS criteria not met

Conclusions:

Novec 7700 has no flash point up to 111 °C according to EU Method A.9.

Executive summary:

The flash point of Novec 7700 was tested using a closed-cup method. Starting at 25 °C, an attempt was made to ignite the vapour of the test substance for every 2 °C temperature rise. No flash was observed below 111 °C, at which temperature the test item showed significant evaporation. The study was conducted in accordance with EU Method A.9 and was GLP compliant; therefore the study is considered reliable without restrictions.

STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: at room temperature

Key result

Auto-ignition temperature:

375 °C

Atm. press.:

> 1 019.7 - < 1 020.2 hPa

The lowest temperature at which ignition of the test item occurred was 377 °C. This temperature was rounded down to the nearest multiple of 5 °C giving an auto-ignition temperature of the test item of 375 °C.

Conclusions:

The auto-flammability temperature of Novec 7700 is 375 °C at 1019.7 - 1020.2 hPa as determined by EU Method A.15.

Executive summary:

The auto-flammability temperature of Novec 7700 is 375 °C at 1019.7 - 1020.2 hPa and was tested using an auto-ignition temperature apparatus. The study was conducted in accordance with EU Method A.15 and was GLP compliant; therefore the study is considered reliable without restrictions.
