Key result

Relative self-ignition temperature:

311 °C

Two strong exothermic effects of the test item were observed. The first exothermic effect of the test item was observed at an oven temperature of 267°C. During this effect, the test item reached a temperature of 353°C. With the second exothermic effect, the temperature of the test item reached 400°C at an oven temperature of 311°C. It demonstrated that the self-ignition temperature of the test item is 311°C. After the experiment, the test item had turned into a charred residue. It indicated that the test item had decomposed and/or reacted during the experiment.

Conclusions:

The self-ignition temperature of the test item was determined using a temperature programmed laboratory oven, a stainless steel wire mesh cube, NiCr/NiAl thermocouples and a temperature recording device. The self-ignition temperature of the test item was 311°C.

Executive summary:

The self-ignition temperature of the test item was investigated in a GLP-compliant study performed in accordance with EC A.16 method. The self-ignition temperature of the test item was 311°C.
