Additional information
The auto ignition temperature of the test material was investigated in accordance with the standardised guidelines EU Method A.15, DIN Guide 51794 and IEC Standard 79-4 under GLP conditions using a commercially available auto-ignition temperature apparatus. The study was awarded a reliability score of 1 in accordance with the principles for assessing data quality set forth by Klimisch et al. (1997).
In every ignition test, liquefied test material was introduced into a preheated test vessel using a volumetric pipette. It was observed visually whether a reaction (clearly perceptible flame and/or explosion) of the sample within five minutes after introduction took place at the prevailing temperature. After each ignition test, any vaporisable components left in the flask were blown out with air.
Three tests were performed, each utilising 3 volumes of test material. Starting at the “high temperature”, for every 2 °C decrease, the prevailing volume of test material was tested until no ignition of the test material had been observed. The temperature at which ignition was last observed is the auto-ignition temperature at the sample volume applied. This procedure was repeated with the other volumes until a minimum auto-ignition temperature for each test was obtained.
Ignition of the test material within 5 minutes after introduction was observed with each sample volume and with each test a minimum auto-ignition temperature was obtained. The maximum deviation between the three values was < 20 °C. The lowest temperature at which ignition of the test material occurred was 366 °C. This temperature was rounded down to the nearest multiple of 5 °C giving an auto-ignition temperature of the test material of 365 °C.
Under the conditions of this study, the test material is auto-ignitable with an auto-ignition temperature of 365 °C at 1012.7 to 1018.4 hPa.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
