Conclusions:
The auto-flammability of N-[(3(5)-Methyl-1 H-pyrazol-1 -yl)-methyl]acetamide was determined according to EU Method A.16 (Relative Self-Ignition Temperature for Solids). The auto-flammability behaviour was determined by placing the test item into a stainless steel cube and heating the environment (GC oven) from room temperature to the upper limit of the melting range (95 °C) of the test item. No increase in the temperature of the sample in comparison to that of the oven could be detected, also no signs of ignition could be observed. Therefore, the test item should be considered as: not auto-flammable.
