Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Auto flammability
Administrative data
Link to relevant study record(s)
- Endpoint:
- auto-ignition temperature (liquids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 17-Jul to 23-Jul-2015
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
- Qualifier:
- according to guideline
- Guideline:
- other: DIN EN 14522, Method S
- GLP compliance:
- no
- Auto-ignition temperature:
- 248 °C
- Atm. press.:
- 1 013 hPa
- Conclusions:
- An auto-ignition temperature of 248 °C was determined in a reliable study conducted according to an appropriate test protocol. It was not compliant with GLP.

Results
Preliminary Test
Lowest test temperature = 279.0 °C
Test Series 1
Lowest test temperature = 252.0 °C
Test Series 2
Lowest test temperature = 252.0 °C
Test Series 3
Lowest test temperature = 252.0 °C

Auto-ignition temperature = 248 °C
Remarks
According to DIN EN 14522 the lowest value of all test series (252 °C) was reduced by the deviation value based on the precision of the method (rel. 1.5% = 3.8 °C). The resulting value was rounded to the next integral number (248 °C).
Description of key information
Triethoxy(phenyl)silane: 248 °C (measured)
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 248 °C
Additional information
An auto-flammability temperature of 248 °C was determined according to EU Method A.15. This is supported by a measured value of 265°C at 1013 hPa from a secondary source (company data). The supporting result is in good agreement with the key study.
