Summary

 

Parameter	Value
Lowest value of test series 1:	292.0 °C
Lowest value of test series 2:	292.0 °C
Lowest value of test series 3:	292.0 °C
Lowest value of all test series	292.0 °C
Absolute deviation of the lowest value (1.5%)	4.4 °C

 

Auto-ignition temperature: 288 °C

 

Remarks

According to DIN EN 14522 the lowest value of all test series (292 °C) was reduced by the deviation value based on the precision of the method (rel. 1.5% = 4.4 °C). The resulting value was rounded to the next integral number (288 °C).

Conclusions:

An auto-ignition temperature of 288 °C was determined in a reliable study conducted according to an appropriate test protocol. It was not compliant with GLP.
