Table 4.12/1 : Ignition attempts pre-test
*During the cleaning process after the
ignition trial at 441.7 of the Pre-test a very big flame with a loud
bang was observed. The upper part of the aperture started to burn. This
also happened after the first detected ignition at 461 °C. Therefore,
the test was stopped.
No main test was conducted.
Atmospheric pressure during the pre-test was
The study was conducted under GLP
according to standard DIN 51794:2003 (listed in EU A.15 guideline).
Due to heavy reactions, observed during
the Pre-test, the determination of the auto ignition temperature of
the test item according to EU A.15 was stopped for safety reasons.
Indeed, during the cleaning process after the ignition trial at
441.7 of the Pre-test a very big flame with a loud bang was
observed. The upper part of the aperture started to burn. This also
happened after the first detected ignition at 461 °C.
Finally the auto-ignition
temperature of the substance was not determined because no
main test was conducted due to heavy reactions observed during the
pre-test above 440°C.
However, considering the elevated temperature
at which the reactions were observed, it is considered that no
particular hazard is anticipated in normal conditions of storage.
Considering the substance as a liquid, the
auto-ignition temperature (for liquids) of the test item was conducted.
Even if no auto-ignition temperature was
determined, pre-test results showed that no particular hazard is
anticipated in normal conditions of storage.
A reliable experimental study, conducted
according to a recognized EU/DIN method and under GLP, is available.
Therefore, it is considered as a key study.
This parameter is not relevant for
classification, however the information is useful regarding process
safety and potential additional fire hazard.
