Description of key information

Single values for the category or individual UVCB members are not applicable. Indicative values for the category  for  vapour pressure range are 4 to 240 kPa at 37.8°C

Key value for chemical safety assessment

Additional information

The vapour pressure range of 4 to 240 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 measured for various low boiling point (gasoline) naphthas according to the EN 13016 -1 method. A range was provided for the vapour pressure because it is not possible to define a single vapour pressure value for a UVCB substance. The quoted range was based on measured values for various category members.
