Description of key information
The flashpoint of Tar wood is stated as:
92.5 °C ± 0.5 °C (corresponding to 365.7 K ± 0.5 K) at 1013 hPa
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 92.5 °C
Additional information
This study was performed in order to determine the flash point of Tar wood. The flash point
is a physico-chemical property which is needed for hazard assessment and safety purposes.
The substance was placed in a test vessel and heated to the test temperature in a Pensky-
Martens apparatus (based on non-equilibrium method). Ignition trials were carried out in
order to ascertain whether or not the sample flashed at the test temperature. The flash
point of a volatile liquid is the lowest temperature at atmospheric pressure (101325 Pa) at
which it can vaporize to form an ignitable mixture in air.
The flash point is given as the mean value of the duplicate determination. The measured
flash point is therefore 92.5 ± 0.5 °C (corresponding to 365.7 K ± 0.5 K) at 1013 hPa.
The difference between the two values which were measured was below 2 K. For this reason,
the determination was considered valid.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
