Key result
Flash point:
40 °C
Atm. press.:
1 003 hPa

Preliminary test:

The estimated flash-point of the test substance was 42.5 °C.

Main study:

The results of the main study on the determination of the flash-point of the test substance are given in table below.

Test  Flash point (°C) Lowest flash-point (°C)
1 62.5
2 40.5 40
3 > 60

Based on the results obtained with the main study it was concluded that the test substance affects the flash-point test. The reason was most likely that the compound reacts with moisture. For safety, the lowest flash point obtained is given as the flash point of the test substance.

Interpretation of results:
Category 3 (flammable liquids) based on GHS criteria

Description of key information

The flash point of the test substance is 40 °C (EC A.9, Pensky-Martens apparatus).

Key value for chemical safety assessment

Flash point at 101 325 Pa:
40 °C

Additional information

The test substance is a 'flammable liquid'. The substance is classified as flammable liquid and vapour Category 3 (H226).
