Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- other: ASTM D7094: “Standard Test Method for Flash Point by Modified Continuously Closed Cup (MCCCFP) Tester”
- Version / remarks:
- 2012
- Deviations:
- not specified
- Principles of method if other than guideline:
- remark of reviewer:
Although ASTM D7094 (modified continuously closed cup) is not mentioned in the EC A.9 guideline, this method is a commonly used and safer (low sample volume) alternative for the ISO 2719 Pensky-Martens closed cup method. - GLP compliance:
- yes
- Type of method:
- non-equilibrium method closed cup
- Flash point apparatus:
- other: Eraflash (Eralytics, Austria)
- Remarks:
- similar principle as Setaflash apparatus
- Dynamic viscosity of test material:
- no data
Test material

- 5-hydroxy-4-propyl-2,5-dihydrofuran-2-one
- Cas Number:
- 78920-10-2
- Molecular formula:
- C7H10O3
- IUPAC Name:
- 5-hydroxy-4-propyl-2,5-dihydrofuran-2-one
- Test material form:
- liquid: viscous
- Details on test material:
- - Appearance: Brown viscous liquid
- Storage condition of test material: At room temperature
Constituent 1
- Specific details on test material used for the study:
- no boiling before decomposition (starts > 175°C)
Results and discussion
Flash point
- Key result
- Flash point:
- 15 °C
- Remarks on result:
- other: mean of 2 measurements
Any other information on results incl. tables
Test 1: 16°C
Test 2: 15°C
As the difference between the results is ≤ 2°C, the lowest flash point value obtained was reported as the flash point of the substance.
Applicant's summary and conclusion
- Interpretation of results:
- other: Category 2 (highly flammable liquids)
- Remarks:
- As boiling of the substance was not observed below or at 35 degrees Celsius in reliable DSC experiments, Category 2 is considered applicable.
- Conclusions:
- The flash-point of the substance was determined to be 15°C (at 1013 hPa).
