- Executive summary:
The flash point of magnesium sulfonate target substance (CAS 231297-75-9) was determined using the closed cup method in accordance to EU Method A.9 (Tremain, 2012). For temperatures up to 100 °C, 2 mL of the test substance was transferred to the sample cup of a Setaflash point tester 30000-0. Above 100 °C, 4 mL of the test substance were applied. The sample was heated and allowed to equilibrate at the set temperature. The test flame was introduced into the sample cup for approximately 254 seconds by sliding the cup shutter open. Observations were made for ignition of the vapor. If no ignition occurred, the temperature was increased and the test flame re-introduced. This was repeated until the lowest reproducible temperature at which a flash occurred, using a fresh sample, was determined. The flash point is the lowest temperature at 101.3 kPa, at which the test liquid in a closed test vessel evolves vapors, under the conditions defined in the test method, in such amount that a flammable vapor / air mixture was produced in the test vessel. 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. Therefore, it was not possible to correct the observed flash point to standard pressure (101.325 kPa).
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 (95.79 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. Therefore, based on a review of historical atmospheric pressure data, and assuming the atmospheric pressure at the time of testing was comparable, it is considered that the flash point value is within the limits specified in the method. As result, the flash point was determined as 168 °C.
Reference
Due to a failure in the instrument used to record the atmospheric pressure, the atmospheric pressure was not recorded during the determination of the flash point of the test item. Therefore, it was not possible to correct the observed flash point to standard pressure (101.325 kPa).
