Key result

Auto-ignition temperature:

320 °C

Atm. press.:

1 014.3 - 1 022 hPa

Preliminary result:

The estimated auto-ignition temperature was 350°C.

Main study:

The results of the main study on the determination of the auto-ignition temperature of the test item are given in Table 1.

Ignition of the test item within 5 minutes after introduction was observed with each sample volume and with each test a minimum auto-ignition temperature was obtained. The maximum deviation between the three values was <20°C. According to the guidelines, no further testing was required. No minimum auto-ignition temperature as a function of injection volume was observed up to the maximum injection volume of 1000 μl.

The lowest temperature at which ignition of the test item occurred was 324°C. This temperature was a multiple of 5°C and is therefore given as the auto-ignition temperature of the test item.

3	250 550 950	333 330 327	13 19 27	Orange/blue Orange/blue Orange/blue	327

Conclusions:

An auto-ignition temperature value of 320°C at 1014.3 – 1022.0 hPa was determined for the substance using a relevant test method and in compliance with GLP. The result is considered to be reliable.
