Description of key information

The vapour pressure for kerosines ranges from <1 to 3.7 kPa at 37.8 °C (CONCAWE 2010a)

Key value for chemical safety assessment

Additional information

The vapour pressure range for kerosines of <1 to 3.7 kPa at 37.8 °C was obtained from the CONCAWE 2010 Compilation of Selected Physico-Chemical Properties of Petroleum Substances report. The vapour pressure was determined according to the EN 13016-1 method.

An additional vapour pressure for kerosines was obtained from the CONCAWE 1994 product dossier. The vapour pressure of straight run kerosine (14 hPa at 37.8°C) was determined according to the ASTM D323 method. The same study found the vapour pressure of jet fuels to be 140 to 210 hPa at 37.8°C according to the ASTM D323 method. This study was classified as reliable with restrictions.
