The measured lowest ignition temperatures of the main test are < 300°C and do not differ by more than 10°C, thus the test is satisfactory.

 

The auto-ignition temperature is defined as the lowest temperature of all single results of the main test, but reduced to the next lower multiple of 5°C.

The auto-ignition temperature of the test item was determined according to EU test method A. 15 (Council Regulation (EC) NO. 440/2008, Official Journal L 142/1 2008) and DIN 51 794 (2003).

Auto-ignition temperature (1009 hPa): 250°C 

 

Conclusions:
An auto-ignition temperature value of 250°C at 1009 hPa was determined in a reliable study conducted according to an appropriate test protocol, and in compliance with GLP.

Additional information

An auto-ignition temperature value of 250°C at 1013 hPa was determined according to EU Test Method A.15. This is supported by a measured flash point value of 260°C (1013 hPa) from a secondary source (company data).
