Results

Preliminary Test

Lowest test temperature = 279.0 °C

 

Test Series 1

Lowest test temperature = 252.0 °C

 

Test Series 2

Lowest test temperature = 252.0 °C

 

Test Series 3

Lowest test temperature = 252.0 °C

Auto-ignition temperature = 248 °C

Remarks

According to DIN EN 14522 the lowest value of all test series (252 °C) was reduced by the deviation value based on the precision of the method (rel. 1.5% = 3.8 °C). The resulting value was rounded to the next integral number (248 °C).

 

Conclusions:
An auto-ignition temperature of 248 °C was determined in a reliable study conducted according to an appropriate test protocol. It was not compliant with GLP.

Description of key information

Triethoxy(phenyl)silane: 248 °C (measured)

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
248 °C

Additional information

An auto-flammability temperature of 248 °C was determined according to EU Method A.15. This is supported by a measured value of 265°C at 1013 hPa from a secondary source (company data). The supporting result is in good agreement with the key study.
