- Atm. press.:
- >= 754 - <= 763 mm Hg
- Remarks on result:
- other: ± 30 °C
- Conclusions:

- Executive summary:
The auto-ignition temperature of the substance was tested under GLP in accordance with standard IEC 60079 -20 -1, Section 7, "Method of Test for Auto-Ignition Temperature", but with 5 °C temperature increments rather than the specified 2 °C increments. The test was carried out with a 200 mL Erlenmeyer flask of borosilicate glass, which was enclosed within a cylindrical furnace that could maintain the surfaces of the flask at a uniform, constant temperature. Surface temperature was monitored by means of thermocouples. A known quantity of test substance was added to the flask, the interior of which was then observed for signs of vapour ignition. The delay time from the addition of test substance to an ignition was recorded. The test was carried out at 20 - 21 °C at 754 to 763 mm Hg atmospheric pressure. No ignition occured at 600 °C with varous sample quantities tested. An ignition was observed at 605 °C with an injection volume of 70 µL and a delay time of 6 - 7 seconds. The auto-ignition temperature of the substance was determined to be 605 ± 30 °C.
