Executive summary:

INTRODUCTION

The auto-ignition temperature of the test item has been evaluated. Method employed was designed to be compatible with Commission Regulation (EC) No 440/2008 of
30 May 2008, Part A: Methods for the determination of physico-chemical properties.

Testing was conducted between 29 April 2010 and 04 May 2010.

Method

The auto-ignition temperature was evaluated by heating aliquots of the test item in a flask and observing for any ignition. Testing was conducted using a method designed to be compatible with Method A15 Auto-Ignition Temperature (Liquids and Gases) ofCommissionRegulation (EC) No 440/2008 of 30 May 2008.

Conclusion

The test item was determined not to have an auto-ignition temperature below 400°C.
