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:
- 29 Aug. to 03 Sept. 2007
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- The study was conducted according to an internationally recognised method, and under GLP. The substance is adequately characterised with its purity. Therefore full validation applies.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.9 (Flash-Point)
- Version / remarks:
- Directive 92/69/EEC
- Qualifier:
- according to guideline
- Guideline:
- ISO 2719 (Determination of flash point - Pensky-Martens closed cup method)
- Version / remarks:
- 2002
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- Certificate from 2007-05-16
- Type of method:
- non-equilibrium method closed cup
- Flash point apparatus:
- Pensky-Martens apparatus
- Dynamic viscosity of test material:
- No data.
- Key result
- Flash point:
- 59 °C
- Atm. press.:
- 101.3 kPa
- Interpretation of results:
- Category 3 (flammable liquids) based on GHS criteria
- Executive summary:
The flash point of the test substance was measured, under GLP, according to EU A.9 / ISO 2719 guidelines, with Pensky-Martens closed cup apparatus. Two runs were performed, and the lowest value was corrected to normal atmospheric pressure, resulting in a flash point of 59°C.
- Endpoint:
- flash point of flammable liquids
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Study period:
- 30 May - 28 June 2005
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Remarks:
- The study was conducted according to an internationally recognised method, and under GLP. However, the test item identification is incomplete (unspecified cis-trans isomery, therefore identified under the generic CAS 17129-06-5). Therefore validation applies with restrictions.

- according to guideline
- Guideline:
- EU Method A.9 (Flash-Point)
- Version / remarks:
- Directive 92/69/EEC
- Qualifier:
- according to guideline
- Guideline:
- ISO 3679 (Determination of flash point - Rapid equilibrium closed cup method)
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- Certificate from 2004-12-22
- Type of method:
- equilibrium method closed cup
- Flash point apparatus:
- Setaflash apparatus
- Dynamic viscosity of test material:
- No data.
- Flash point:
- 56 °C
- Atm. press.:
- 101.3 kPa
- Interpretation of results:
- Category 3 (flammable liquids) based on GHS criteria
- Executive summary:
The flash point of the test substance was measured, under GLP, according to EU A.9 / ISO 3679 guidelines, with Setaflash closed cup apparatus. Two runs were performed, and the average value was corrected to normal atmospheric pressure, resulting in a flash point of 56°C.

Preliminary test
The flash point was estimated to be 60°C.
Main study
| Test | Measured flash point [°C] | Lowest (corrected) flash point [°C] |
| 1 | 59 | 59 |
| 2 | 61 |
In the first series of test, ignition of the vapour phase was observed at 56.5°C (atmospheric pressure 101.989 kPa).
In the second series, ignition of the vapour phase was observed at 55.5°C (atmospheric pressure 101.989 kPa).
Upon correction for the atmospheric pressure and averaging, the resulting flash point is 56.0°C.
Description of key information
The substance is classified as Flammable Liquid category 3, according to CLP Regulation criteria (and UN GHS).
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 59 °C
Additional information
Two experimental studies are available, both conducted according to EU/ISO guideline and GLP:
- The measurement with the Pensky-Martens apparatus, presented in Notox 2007 report, was considered as fully reliable. The result is retained as key data.
- The measurement with the Setaflash apparatus, in TNO 2005 report, was assigned lower reliability, due to incomplete test item identification (i.e. unspecified cis-trans isomery), so included as supporting data.
The results (59 and 56°C, respectively) are consistent, considering the accuracy of the determination (within +/-2°C of the mean), and lead to the same classification according to GHS/CLP criteria (see IUCLID Section 4.13 endpoint summary for justification of classification).
