- Executive summary:
A study was conducted to determine the self-ignition temperature of the test substance, TMAC C (99.6% active), according to EU Method A.16 and in compliance with GLP. 8 cm3 (2.6 g) of the test substance was placed in an oven at 23°C. The temperature-time curve relating to condition in the centre of the sample was recorded while the temperature of the oven was increased to 400°C at a rate of 0.5°C/minute. Under the study conditions, no self-ignition temperature was observed up to the maximum temperature of 405°C (Smeykal, 2008).
Reference
The test substance showed a small exothermic reaction in the temperature range of 175 - 230°C and no further exothermal reaction of the test substance was observed up to a maximum temperature of 405°C.
Two DSC measurements in closed glass crucibles with the test substance showed endothermic effects in the temperature range 35 - 80°C, 225 - 270°C (double peak) and 305 - 320°C and no exothermal effect up to the maximum test temperature of 400°C.
Description of key information
Under the study conditions, no self-ignition temperature was observed up to the maximum temperature of 405°C.Key value for chemical safety assessment
Additional information
The self-ignition temperature was determined according to EU Method A.16 (Smeykal, 2008).
