Guideline:
DIN 51794 (Testing of mineral oil hydrocarbons - Determination of ignition temperature)

yes
Specific details on test material used for the study:
Clear colourless liquid
Purity: 97.2%
Auto-ignition temperature:
235 °C
Atm. press.:
1 017 hPa

Ignition of the test item within 5 minutes after introduction was observed with each sample volume and with each test a minimum auto-ignition temperature was obtained. The maximum deviation between the three values was < 10°C. According to the guidelines, no further testing was required. The lowest temperature at which ignition of the test item occurred was 238°C. This temperature was rounded down to the nearest multiple of 5°C giving an auto-ignition temperature of the test item of 235°C.

Conclusions:
Commercially available auto-ignition temperature apparatus was used for the determination of the degree of auto-ignitability of 1,1’-(1,1,3-trimethylpropane-1,3-diyl)bis(cyclohexane). The test item is auto-ignitable with an auto-ignition temperature of 235°C. The atmospheric pressure was 1017 hPa.
Executive summary:

Commercially available auto-ignition temperature apparatus was used for the determination of the degree of auto-ignitability of 1,1’-(1,1,3-trimethylpropane-1,3-diyl)bis(cyclohexane). The test item is auto-ignitable with an auto-ignition temperature of 235°C. The atmospheric pressure was 1017 hPa.
