Mean value* = 60.0 °C

* The mean value is calculated from test 1 and 2 and rounded to ± 0.5 °C 

Determination of the corrected flash-point:

 

TC = T0+ 0.25 x (101.3 – p)

TC = corrected flash point to the standard atmospheric pressure (101.3 kPa)

T0= measured flash point at actual atmospheric pressure

p = actual atmospheric pressure [kPa]

Conclusions:
A flash point value of 60.0 °C at 967 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): 60.0°C at 967 hPa (measured)

Key value for chemical safety assessment

Flash point at 101 325 Pa:
60 °C

Additional information

A flash point value of 60.0 °C at 967 hPa was determined by equilibrium method closed cup method according to EU Method A.9 . This is supported by measured values of 54 °C and 52 °C obtained from secondary sources (company data and MSDS respectively).
