Room temperature: 20 to 21°C

Atmospheric pressure: 99.8 to 100.8 kPa

Conclusions:
An auto-ignition temperature of 204 ± 5°C at 99.8 - 100.8 kPa was determined for the substance using relevant test method. The result is considered reliable
Executive summary:

The determination was carried out using a procedure[1]designed to be compatible with Method A15 Auto-Ignition Temperature (Liquids and Gases) of Commission Regulation (EC) No 440/2008 of 30 May 2008.


[1]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 204 ± 5 °C.

 

Description of key information
