Description of key information
Auto-flammability: 245°C (ASTM E918-83)
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 245 °C
Additional information
Two measured studies are available for the auto-flammability of the submission substance. In the first study (Dow Corning 2014: summary of previous study results), the auto-ignition temperature study of trimethylsilane was conducted in accordance with ASTM E918-83 (93). The test apparatus was made up of a 1 litre stainless steel chamber which is heated uniformly to a predetermined temperature. The auto-ignition temperature determined for trimethylsilane is 245°C at 1013 hPa. Although, the study is not conducted in accordance with GLP, the test laboratory has an internal quality system being an authorised US DOT explosives test facility. This result is considered to be reliable and is selected as key study.
In the second study (Griffiths 1958); the auto-ignition study of trimethylsilane was determined using a drop technique. The spontaneous ignition temperatures were determined at a fixed delay time of 5 seconds and with a fuel/air ratio controlled between the limits of two and three times the stoichiometric requirement. An auto-ignition temperature of 320°C was obtained for the submission substance.
The key study is selected as the lowest measured auto-ignition temperature using a conservative approach. In addition, the second study lacks information on the test material and at what atmospheric pressure the study was conducted.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
