The auto-ignition temperature was situated between 302°C and 260°C (corrected values). This range is given for information; the final result is given by the main test in following section.

Main test:

Volume of test item injected in the oven                    70µL

 

Only the runs with an auto-ignition observed for each assay are summarised in the following table:

 

	Auto-ignition temperature (°C)		Auto-ignition	Maximal temperature of the air recorded in the center of the test flask after ignition (°C)		Atmospheric pressure (kPa)	Relative humidity (%)
Assay No.	Observed	Corrected	Lag (s)	Observed	Corrected
1	260	261	30	284	285	98.4	42
2	260	261	24	283	284	98.3	45

5	261	262	25	283	284	97.9	42

 

Conclusion:

The lowest value of the main test series was 261°C ± 3°C (corrected temperature) and the auto-ignition temperature of the test item was 260°C (reduced down to the next lower multiple of 5°C).

Conclusions:

An auto-ignition temperature value of 260 ± 3°C was determined for the substance using a relevant test method. The result is considered to be reliable.
