Room temperature:                20 °C

Atmospheric pressure:100.6 to 101.9 kPa

Conclusions:

A measured auto-ignition temperature of 212 ± 5°C at 100.6 to 101.9 kPa was determined for the substance using a 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 212 ± 5 °C.
