no

GLP compliance:

yes

Key result

Remarks on result:

other: Exothermic effect of the test item by self-heating was observed at an oven temp. of 228°C. During this the test item reached a temp. of 389°C. According to the guideline, a test item is self-ignitable when the sample temp. reaches 400°C by self-heating.

Conclusions:

The GLP study was performed according to EU method A.16 without deviations and therefore reliability of Klimisch 1 has been assigned. The substance does not reach 400 °C by self-heating under the conditions of the test.

Executive summary:

The auto ignition temperature of the test substance was determined in a GLP test according to EU method A.16.

An exothermic effect of the test item by self-heating was observed at an oven temperature of 228°C. During this effect the test item reached a temperature of 389°C. According to the guideline, a test item is self-ignitable when the sample temperature reaches 400°C by self-heating. Based on this the test item is considered ‘not self-ignitable’. After the experiment, the test item had turned into a charred black residue and was collected in a container that was placed below the cube. It indicated that the test item had been molten, decomposed and/or reacted during the experiment.
