Results and discussion

Flash point
Flash point:
122 °C
Remarks on result:
other: not corrected to standard atmospheric pressure

Any other information on results incl. tables

Due to an instrument failure the atmospheric pressure was not recorded, and therefore it was not possible to correct the observed flash point to standard atmospheric pressure. Historical data of atmospheric pressure at Harlan Laboratories in Shardlow, covering the period 02 January 2008 to 31 December 2008 was used to obtain the highest and lowest atmospheric pressure values over this period. The flash point was then corrected to standard atmospheric pressure, using the highest atmospheric value (957.9 kPa) and the lowest atmospheric pressure value (103.93 kPa). The resulting pair of corrected flash point values were within ±2°C of the observed flash point.

Applicant's summary and conclusion

Conclusions:
The flash point of Cassia oil is 122ºC.
Executive summary:

The flash point of Cassia oil was investigated according to EU Method A.9 using the closed cup method under GLP. The flash point was found to be 122ºC (not corrected for atmospheric pressure).
