Referenceopen allclose all
The pressure 1013 hPa is assumed since the pressure should be corrected to 1013 hPa by the system.

* 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]

Description of key information
Diethoxy(methyl)silane: 1.0°C at 1013 hPa (Abel closed cup method, EU Method A.9.)
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 1 °C
Additional information
A flash point of 1.0°C at 1013 hPa was determined for the test substance according to EU Method A.9 (Abel closed cup method). This is supported by a measured value of 1.5 °C at 1013 hPa (closed cup equilibrium method).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
