Atmospheric pressure = 101.6 kPa

Corrected flash point = 197.94 ºC

Conclusions:

Under the study conditions, the flash point of the test substance was determined to be 198 ± 2 °C.

Executive summary:

A study was conducted to determine the flash point of the test substance, trichloro(N,N-dimethyloctylamine)boron using using a closed cup equilibrium method according to EU method A9 in complaince with GLP. An aliquot of the test substance 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. Under the study conditions, the flash point of the test substance was determined to be 198 ± 2 °C (Harlan, 2014).
