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:
- May 13 to July 24, 2009
- 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. The substance is adequately identified, but the composition is incomplete. Therefore validation applies with restrictions.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.9 (Flash-Point)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- effective from 16/07/2008
- Type of method:
- closed cup
- Flash point apparatus:
- Setaflash apparatus
- Dynamic viscosity of test material:
- no data
- Specific details on test material used for the study:
- Storage condition of test material: Stored at room temperature protected from direct sun light.
- Key result
- Flash point:
- 147 °C
- Atm. press.:
- ca. 1 atm
- Interpretation of results:
- GHS criteria not met
- Remarks:
- GHS and EU-CLP criteria not met
- Conclusions:
- The flash point of the test substance is above the classification thresholds of 60 °C (CLP criteria) or 93°C (GHS criteria). Therefore, the test substance is NOT a flammable liquid according to CLP and GHS criteria.
- Executive summary:
The flash point of the test substance was determined under GLP according to EU A.9 guideline, using a closed cup method with Setaflash apparatus.
After a screening determination, two main runs were performed, and found consistent. The average result was retained, and rounded down to the nearest integer.
The flash point of the test substance has been determined to be147°C.
Reference
In a first test, the temperature was increased by successive steps of +5.0 °C, using 4 mL of sample. Flashing occurred at 150 °C.
The procedure was reproduced using a new 4.0 mL sample for each replicate test, and the temperature was regularly increased by successive steps of 0.5 °C. Flashing occurred at 147.5 °C and 148.0 °C successively. The mean value for flash point was calculated out from the two replicate measurements. Mean flash point = 147.8 °C ± 0.4 °C
Reference material: diethyl-phthalate. Nominal flash point = 159 ±3 °C. Measured flash point = 162.0 °C.
Description of key information
The substance is NOT classified as flammable liquid neither according to CLP Regulation criteria, nor to UN GHS.
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 147 °C
Additional information
A reliable experimental study, conducted according to a recognized EC guideline and under GLP, is available.
Despite restrictions due to incomplete test item identification it is considered as key study, and the result is retained as key data.
