- 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
- 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.
Reference
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.
Description of key information
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.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 235 °C
