Key result

Flash point:

40 °C

Atm. press.:

100 kPa

Interpretation of results:

Category 3 (flammable liquids) based on GHS criteria

Conclusions:

40 ± 2 °C, using a closed cup equilibrium method designed to be compatible with Method A.9 Flash Point of Commission Regulation (EC) No 440/2008 of 30 May 2008

Executive summary:

The determination was carried out using a closed cup flash point tester using a procedure designed to be compatible with Method A.9. An aliquot (2 mL) of the test item was transferred to the sample cup of the Setaflash 30000-0 tester. The sample was heated and allowed to equilibrate at the set temperature. The test flame was introduced into the sample cup for approximately 2½ 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 of the test item has been determined to be 40 ± 2 °C at atmospheric pressure of 100.9 kPa.
