Key result
Auto-ignition temperature:
260 °C
Atm. press.:
> 984.5 - < 989.8 hPa
Remarks on result:
other: Based on the results of the main test series, the lowest auto-ignition temperature was 262°C. Rounded down to the nearest multiple of 5°C the auto-ignition temperature was determined as 260°C.

The auto-ignition temperature was rounded down to the nearest multiple of 5°C was determined as 260°C, according to Regulation EC No. 440/2008 and DIN 51794. According to DIN EN 14522, the auto-ignition temperature reduced by 1.5% and rounded to the nearest integer temperature was determined as 258°C.

Conclusions:
The test item has an auto-ignition temperature of 260 °C according to the Regulation EC No. 440/2008 Method A.15 Auto-ignition temperature (liquids and gases). According to DIN EN 13463-1 the test item has been assigned to temperature class T3 (maximum surface temperature / minimum auto-ignition temperature 200 °C).
Executive summary:

The auto-ignition temperature of the test item was investigated in study conducted according to the European Commission Regulation No. 440/2008, Method A.15.

A preliminary test, and three main tests were conducted for the calculation of the auto-ignition temperature. The test item has an auto-ignition temperature of 260°C according to the Regulation EC No. 440/2008 Method A.15 Auto-ignition temperature (liquids and gases). According to DIN EN 13463-1 the test item has been assigned to temperature class T3 (maximum surface temperature / minimum auto-ignition temperature 200°C).

The study is a guideline experimental study and is adequate for assessment of this endpoint (Klimisch 1).
