- 99 °C
- Atm. press.:
- 1 003 hPa
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- A flash point of 99°C at 1013 hPa was determined for the substance using a relevant test method and in compliance with GLP. The result is considered reliable.
Reference
Preliminary study result:
The estimated flash-point of the test substance was 95°C.
Main study result:
The results of the main study on the determination of the flash-point of the test substance are shown in Table 1. The difference between the results obtained with the two tests was = 2°C. From this, it was concluded that the flash-point of the test substance is the lowest flash-point obtained.

Description of key information
Flash point: 99°C at 1013 hPa (ISO 2719)
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 99 °C
Additional information
There are two reliable flash point values for methylsilanetriyl triacetate. A measured flash point of 99°C at 1003 hPa was determined for the substance using a relevant test method and in compliance with GLP. The result was considered to be reliable and is selected as key study. In a handbook or collections of reliable data in which the original sources are traceable, flash point value of 85°C at 1013 hPa was reported for the substance. The key study was selected as the study that was recently conducted and with the highest reliability.
In the available secondary sources to which reliability could not be assigned, flash point values of 85°C and 99°C were reported for the substance.
A flash point of 99°C at 1013 hPa with a boiling point of 206 - 220°C at 1013 hPa, indicates that the substance should not be classified for flammability according to the criteria of Regulation (EC) No. 1272/2008.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
