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
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with national standard methods
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.9 (Flash-Point)
- GLP compliance:
- no
- Type of method:
- closed cup
- Remarks:
- ISO 3679
- Key result
- Flash point:
- 117 °C
- Atm. press.:
- 101.3 kPa
- Conclusions:
- The flash of n-heptanoic acid corrected at the pressure of 101.3 kPa, was 117°C ± 0.5°C.
- Executive summary:
The flash point of n-heptanoic acid was determinated according to according to Commission Regulation (EC) No 440/2008 , part A.9 following the closed cup method ( ISO 3679).
The observation between 112 and 122°C, obtained at each equilibrium measurements, are reported at 988 mbars. The flash point is the lowest temperature at which the sample produces vapour in a closed container (closed cup) in such amounts that a flammable vapour/air mixture is formed.
The flash of n-heptanoic acid corrected at the pressure of 101.3 kPa, was 117°C ± 0.5°C.
Reference
The observation and results obtained at each equilibrium measurements are reported in the table below:
| Temperature set (°C) | Corrected temperature (°C) | Test result | Comments | |
| Positive | Negative | |||
| 112 | 112.7 | X | No Flash - detected by equipment | |
| 122 | 122.7 | X | Flash - detected by equipment | |
| 116 | 116.7 | X | No Flash | |
| 118 | 118.7 | X | Flash - detected by equipment | |
| 117 | 117.7 | X | Flash - detected by equipment | |
| 116.5 | 117.2 | X | Flash - detected by equipment | |
| 116 | 116.7 | X | flash | |
| Flash point = 116.5°C for set point – 117°C correct ed rounded to closest lower value flash point | ||||
The corrected flash point is obtained as followed:
| Flash point observed (ISO 3679) (measured) | Pressure effect correction | Atmospheric pressure the day of determination (24/08/2009) |
Corrected flash point, value at the nearest 0.5°C | |
| n-heptanal n° 0038/08, lot 0805027 |
116.5°C | 0.7°C | 988 mbars | 117°C |
