- no
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EPA OPPTS 830.6315 (Flammability)
- Deviations:

- GLP compliance:
- yes
- Type of method:
- closed cup
- Flash point apparatus:
- Pensky-Martens apparatus
- Flash point:
- 158 °C
- Atm. press.:
- 1 013.25 hPa
- Remarks on result:
- other: Flash point mean (n=2)
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The flash point of the test item has been determined to be 158°C at 101.325 kPa.
- Executive summary:
The flash point was determined using DIN 51758 and EU Method A.9 under GLP. The test item was transferred to the sample cup of the Pensky-Mertens closed cup tester and replicate measurements of flashpoint were made corrected to 101.325 kPa atmospheric pressure. The flash point of the test substance has been determined to be 158°C at 101.325 kPa.

An existing value from a previous experiment using noncompliant equipment was already known; however in the current study, this was determined to be incorrect and the preliminary measurement was repeated with a result of 155°C
The result of the main-test is summarized in the following table. The result "ignition" is indicated by + and "no ignition" by -.
