Key result
Auto-ignition temperature:
235 °C
Remarks on result:
other: atm. pressure not specified
Remarks:
Accuracy of measurement : +/- 5 °C

The lowest temperature giving a positive effect was 239°C. The injected volume was 100µl, the ignition delay was 54 s. At a temperature of 234°C no ignition was observed.

 

Therefore, after rounding-off to the next-lower multiple of 5°C:

 

Auto-ignition temperature of GR-87-7596: 235±5°C

Conclusions:
Auto-ignition temperature of GR-87-7596: 235 ± 5°C
Executive summary:

The Auto-ignition temperature of GR-87-7596 was determined in a SUR BERLIN oven, equipped with a 250 ml glass ignition vessel according to the DIN 51794.

 

The lowest temperature giving a positive effect was 239°C. The injected volume was 100µl, the ignition delay was 54 s. At a temperature of 234°C no ignition was observed.

 

Therefore, after rounding-off to the next-lower multiple of 5°C:

 

Auto-ignition temperature of GR-87-7596: 235 ± 5°C
