- Key result
- Flash point:
- 45 °C
- Atm. press.:
- 100 kPa
- Interpretation of results:
- Category 3 (flammable liquids) based on GHS criteria
- Conclusions:
- In a relevant and conclusive study, the flash point of the test substance was found to be 45 ± 2°C.
- Executive summary:
The flash point of the test substance has been determined according to ASTM D93 standard for Pensky-Martens closed-cup testing under GLP. The experiment is considered relevant, adequate and conclusive.
Approximately 70 mL of the test substance was placed in a test cup closed by a lid and heated at a specified rate with stirring. At 1 °C increments a small test flame was automatically introduced into the vapour space above the liquid through a temporary opening in the lid. A flash was detected by a thermocouple suspended in the vapour space in two experiments and the flash point of the substance was found to be 45 ± 2 °C at atmospheric pressure and the substance is categorised as flammable liquid, Cat. 3, based on GHS.
Reference
Sample preparation: Tested as received.
Heating rate: 1.3 °C/minute (slow ramp rate from Method B).
Stirring rate: 120 rpm (stirring rate from Method A)
Two flash point determinations were performed:
Test 1: temperature range from 21 to 45 °C, measured value: 45 °C
Test 2: temperature range from 19 to 45 °C, measured value: 44.5 °C
Description of key information
In a valid, reliable and conclusive study, the flash point of the test substance was found to be 45 ± 2 °C.
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 45 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
