Main test
Taking into account the results obtained during the preliminary assay, no main test was performed.
Conclusion
Only a preliminary test was performed: No auto-ignition temperature was observed up to 601 °C (corrected value).
Description of key information
Trichloro(4-methylphenyl)silane: > 601 °C at 980 hPa (EU method A.15)
Key value for chemical safety assessment
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
