Conclusions:
The tested substance "LAB 4448" did not show any auto-ignition temperature up to 400°C.
Executive summary:

The substance "LAB 4448" was tested for its auto-flammability according to EU method A.15 and in compliance with GLP.

The starting temperature was approximately 230°C and the steps for increasing the temperature was approximately 50°C. The test was carried out at 98.0 kPa atmospheric pressure. The ignition delay time was determined when ignition was observed. No ignition was observed up to 400°C with the tested sample LAB 4448. So LAB 4448 did not show any auto-ignition temperature up to 400°C.

The auto-flammability study is acceptable, and satisfies the requirements of the EU method A.15.
