Flash point
Administrative data
Link to relevant study record(s)
- Endpoint:
- flash point, other
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 1994-02-18 to 1994-03-02
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- The EU Method A.9 is applicable to liquid substances or low melting solids whose vapours can be ignited by ignition sources, only. Since the substances melts at 51.9 °C, the test system is considered as valid for that test item.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.9 (Flash-Point)
- Version / remarks:
- 1992
- Deviations:
- yes
- Remarks:
- The test item is a low melting point solid and therefore a syringe could not be used to add the test material to the sample cup. Instead the test material was weighed into the sample cup.
- Qualifier:
- according to guideline
- Guideline:
- ISO 1523 (Determination of flash point - Closed cup equilibrium method)
- Version / remarks:
- 1983
- Deviations:
- not specified
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- signed 1994-03-16
- Type of method:
- equilibrium method closed cup
- Flash point apparatus:
- other: no data
- Key result
- Flash point:
- 157 °C
- Atm. press.:
- 101.83 kPa
- Remarks on result:
- other: ± 2 °C
- Interpretation of results:
- other: According to CLP regulation, a substance is not considered flammable when the flash point is greater than 60 °C.
- Conclusions:
- According to Council Directive 92/69/EEC A.9, the flash point of the test item was determined to be 157 ± 2 °C at 101.83 kPa.

Description of key information
The flash point of the test item was determined to be 157 ± 2 °C at 101.83 kPa.
The EU Method A.9 is applicable to liquid substances or low melting solids (i.e., < 160°C) whose vapours can be ignited by ignition sources, only. Since the melting point of the test item is 52 °C, the test system is considered as valid for that substance.
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 157 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
