Key result
Auto-ignition temperature:
395 °C
Atm. press.:
1 028.8 hPa

Preliminary test: Starting at 186°C and testing every 20°C, a flame was observed at 439°C.

Going down from 439°C and testing every 5°C, an auto-ignition temperature of 405°C was determined.

 

Main study: The lowest measured auto-ignition temperature was 397°C at an injection volume of 85 µl and with a time lag of 10 s. Rounded down to the nearest 5°C gives the auto-ignition temperature for Hatcol 2352: 395°C.

The atmospheric pressure was 1028.8 hPa during the preliminary test and Test 1. The atmospheric pressure was 1025.4 hPa during Test 2 and Test 3.
