Results

 

Preliminary test series: Ignition at 260 °C, no ignition at 240 °C

First main test series: Ignition at 241 °C, no ignition at 239 °C

Second main test series: Ignition at 239 °C, no ignition at 237 °C

Retest: Ignition at 239 °C, no ignition at 237 °C

 

Evaluation

Lowest value from pretest	260 °C
lowest value for first main test	241 °C
lowest value for second main test	239 °C
Lowest value from pretest	239 °C

Lowest value of all main test/retest series: 239 °C

Correction of the temperature according to the last DKD calibration (06/2015) of the temperature measurement chain (thermocouple + monitor) is already considered (value of -0.5 °C).

 

Concluding result

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: 235 °C

Conclusions:

An auto-ignition temperature of 235 °C at 1013 hPa was determined in a reliable study conducted according to an appropriate test protocol, and in compliance with GLP.

Description of key information

235°C at 1013 hPa (EU Method A.15) 

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:

235 °C

Additional information

The key value is supported by measured values of 234°C (at 1013 hPa) and approximately 245°C from a secondary source (company data). The supporting results are in good agreement with the key study.
