Reference
Endpoint:
flash point of flammable liquids
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.9 (Flash-Point)
Deviations:
no
Qualifier:
according to guideline
Guideline:
other: DIN EN ISO 13736
Deviations:
no
Principles of method if other than guideline:
The test portion was placed in the test cup of a Abel apparatus and heated to give a constant temperature increase with continuous stirring. An ignition was directed through an opening in the test cup lid at regular temperature intervals with simultaneous interruption of stirring. The lowest temperature at which the application of the ignition source causes the vapor of the test portion to ignite and propagate over the surface of the liquid is defined as the flash point at the ambient barometric pressure (1026 hPa). This temperature was corrected automatically by the apparatus to standard atmospheric pressure (1013 hPa). A gas flame was used as the ignition source.
GLP compliance:

The lowest temperature at which the application of the ignition source causes the vapor of the test portion to ignite and propagate over the surface of the liquid is defined as the flash point at the ambient barometric pressure (1026 hPa). This temperature was corrected automatically by the apparatus to standard atmospheric pressure (1013 hPa).

Interpretation of results:
Category 3 (flammable liquids) based on GHS criteria
Conclusions:
The test to analyse flash point to 2,2,4-Trimethyl-1-oxa-4-aza-2-silacyclohexane showed a flash point of 27.5°C at 1013 hPa.
Executive summary:

The test to analyse flash point to 2,2,4-Trimethyl-1-oxa-4-aza-2-silacyclohexane was performed as stipulated in EC Test Procedure A.9 (EIN EN ISO 13736, closed cup). The test portion was placed in the test cup of a Abel apparatus and heated to give a constant temperature increase with continuous stirring. This temperature was corrected automatically by the apparatus to standard atmospheric pressure (1013 hPa).

A gas flame was used as the ignition source. Ignitions were visually determined by the tester. Ignition was determined in the pre-test at 30.0°C. In the main-tests ignitions were determined at 28.0°C and 27.0°C. The average value of the main-tests (to the nearest 0.5°C) is 27.5°C.
