Executive summary:

SUMMARY

The auto-ignition temperature were determined using methods specified in Commission Regulation (EC) No 440/2008 of 30 May 2008.

Result

Auto-Ignition Temperature (Liquids and Gases)

A15

None below 400°C.

The flash point and auto-ignition temperature of the test material have been determined. Methods employed were those specified in Commission Regulation (EC) No 440/2008 of 30 May 2008, Part A: Methods for the determination of physico-chemical properties. Testing was conducted between 22 December 2009 and 23 December 2009. The auto-ignition temperature was determined by heating aliquots of the test material in a flask and observing for any ignition. Testing was conducted using Method A15 Auto-Ignition Temperature (Liquids and Gases) of CommissionRegulation (EC) No 440/2008 of 30 May 2008. The test material has been determined not to have an auto-ignition temperature below 400°C.
