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:
- 17th Oct 2019- 21st Oct 2019
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with national standard methods
- Qualifier:
- according to guideline
- Guideline:
- other: ASTM D7094
- Version / remarks:
- Standard Method for Flash Point Modified Continuously Closed Cup (MCCCFP) Tester, 2012
- Deviations:
- yes
- Remarks:
- Due to the low flash-point of the test item and the start temperature used, the flash-point temperature was < 18°C from the temperature of the first application of the ignition source and no additional test with an adjusted start temperature was performed
- GLP compliance:
- yes (incl. QA statement)
- Other quality assurance:
- ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)
- Remarks:
- ISO 9001
- Type of method:
- closed cup
- Flash point apparatus:
- other: Eraflash flash-point tester
- Key result
- Flash point:
- -17 °C
- Atm. press.:
- 1 013 hPa
- Interpretation of results:
- Category 2 (highly flammable liquids) based on GHS criteria
- Conclusions:
- A flash point of -17°C at 1013 hPa was determined for the test substance using an appropriate test guideline and in compliance with GLP. This result is considered reliable.

Description of key information
The flash point of propane-1-thiol is -17˚C
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- -17 °C
Additional information
A measured flash point value of -17°C at 1013 hPa was determined for the substance according to testing method ASTM D7094. This result is considered reliable and is selected as key.
The key result is supported by a flash point value of -20°C. No information on the primary source of the supporting data or the methods used is available. However, this information is taken from an internationally peer-reviewed chemical safety card (IPCS 2006) and can be considered reliable.
A flash point of -17°C at 1013 hPa and boiling point of 68°C at 1013 hPa indicate that the substance should be classified for flammability in accordance with Regulation (EC) No. 1272/2008.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
