Results

Preliminary Test

Lowest test temperature = 355.7 °C at 964 hPa

 

Test Series 1

Lowest test temperature = 309 °C at 959 - 962 hPa

 

Test Series 2

Lowest test temperature = 307 °C at 961 hPa

 

Test Series 3

Lowest test temperature = 307 °C at 964 hPa

Auto-ignition temperature = 302 °C

Remarks

According to DIN EN 14522 the lowest value of all test series (307 °C) was reduced by the deviation value based on the precision of the method (rel. 1.5% = 4.6 °C). The resulting value was rounded to the next integral number (302 °C).

 

Conclusions:
An auto-ignition temperature of 302 °C at approx. 960 hPa was determined in a reliable study conducted according to an appropriate test protocol. It was not compliant with GLP.

Description of key information

Trimethoxy(2,4,4-trimethylpentyl)silane): 302 °C at approx. 960 hPa

Key value for chemical safety assessment

Additional information

An auto-ignition temperature of 302 °C (at approximately 960 hPa) was determined according to EU Method A.15. This is supported by a measured value of 310 °C obtained from a secondary source (MSDS).
