Key result

Remarks on result:

no self ignition observed under the test conditions

An exothermic effect of the test item by self-heating was observed at an oven temperature of 164 °C. During this effect the test item reached a temperature of 198 °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 residue and was partially collected in a container that was placed below the cube. It indicated that the test item had been partially molten, 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. Based on the results obtained the test item is considered ‘not self-ignitable’.

Executive summary:

The study was performed based on procedures in the EU Method A.16 (Relative Self-Ignition Temperature for Solids). 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. An exothermic effect of the test item by self-heating was observed at an oven temperature of 164 °C, during this effect the test item reached a temperature of 198 °C. However, according to the guideline, a test item is self-ignitable when the sample temperature reaches 400 °C by self-heating. Based on the results obtained the test item is considered ‘not self-ignitable’.
