Room temperature:    20 to 21 °C
Atmospheric pressure: 99.9 to 100.9 kPa

Conclusions:
The test item has been determined to have an auto-ignition temperature of 416 ± 5 °C. The auto-ignition of the test item did not appear to be volume dependant.
Executive summary:

The determination was carried out using a procedure* designed to be compatible with Method A15 Auto-Ignition Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008.

 


* Based on Anon (1987) Electrical Apparatus for Explosive Gas Atmospheres, Part 4: Method of Test for Ignition Temperature,IEC Publications79-4, P1-19.

Conclusion

The test item has been determined to have an auto-ignition temperature of 416 ± 5 °C. The auto-ignition of the test item did not appear to be volume dependant.

Description of key information

The auto ignition temperature of the substance has been determined to be 416 °C at 99.9 – 100.9 kPa.
