Flash point
Administrative data
Link to relevant study record(s)
- Endpoint:
- flash point of flammable liquids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2017-10-18 to 2017-11-03
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EU Method A.9 (Flash-Point)
- Deviations:
- no
- Principles of method if other than guideline:
- The study was performed according to SOP No. SPO/BC/09/b "Determination of flash point - Pensky-Martens closed cup method standard". This test method is based on PN-EN ISO 2719: 2016 "Determination of flash point - Pensky-Martens closed cup method". This method corresponds to method A.9 Flash point.
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- closed cup
- Flash point apparatus:
- Pensky-Martens apparatus
- Specific details on test material used for the study:
- - Appearance: yellowish liquid
- Composition: 95.4 % MAC, 1.6 % MAC-Dimer, 2.9 % Acetone oxime
- Purity: 95.4 %
- Batch No.: 20160817
- Expiry date: 16.08.2018 - Key result
- Flash point:
- 84 °C
- Atm. press.:
- 101.3 kPa
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The flash point of methyl-tris acetonoximo-silane (MAC) is 84.0 °C.
- Executive summary:
The flash point of methyl-tris acetonoximo-silane (MAC), which was determined by using a Pensky-Martens apparatus according to EU method A.9, is 84.0 °C. Based on criteria set in the CLP regulation the test item is not a flammable liquid, as the determined flash point is > 60 °C.

The value of the flash point was corrected due to the deviation of the thermometer and atmospheric pressure.
C: Determined flash point after including a thermometer deviation = 83.8 °C
p: Ambient barometric pressure = 101.1 kPa
T = C + 0.25 (101.3 - p) = 83.8 °C + 0.25 (101.3 kPa - 101.1 kPa) = 83.85 °C ~ 84 °C (measurement uncertainty: 1.2 °C)
Description of key information
The flash point of methyl-tris acetonoximo-silane (MAC), which was determined by using a Pensky-Martens apparatus according to EU method A.9, is 84.0 °C. Based on criteria set in the CLP Regulation 1272/2008 the test item is not a flammable liquid, as the determined flash point is > 60 °C.
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 84 °C
