An exothermic reaction occurred at 180°C and led to a maximum temperature of 438 °C. The temperature of the test item exceeded 400°C at a corresponding oven temperature of 356 °C.

Conclusions:

The relative self-ignition temperature is 356°C, according to the testing guideline for autoflammability (solids - determination of relative self-ignition temperature) in the sense of the consolidated version of Council Directive 67/548/EEC Annex V (Council Directive 92/69/EEC), Method A.16.

Executive summary:

The purpose of this study was the determination of the relative self-ignition temperature of the test item according to the consolidated version of Council Directive 67/548/EEC Annex V (Council Directive 92/69/EEC), Part A: Methods for the determination of physico-chemical properties, A.16. Auto-flammability (solids - determination of relative self-ignition temperature). The study was performed in accordance with the Principles of Good Laboratory Practice (GLP) and reported with a valid GLP certificate.

 

8 cm³(5.0 g) of the test item were placed in an oven at 23°C. The temperature/time curve relating to conditions 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/min.

The temperature of the oven at which the sample temperature reaches 400°C by self-heating is called the self-ignition temperature for the purpose of this test.

 

An exothermic reaction occurred at 180°C and led to a maximum temperature of 438 °C. The temperature of the test item exceeded 400°C at a corresponding oven temperature of 356 °C.

 

The relative self-ignition temperature is 356°C, according to the testing guideline for auto-flammability (solids - determination of relative self-ignition temperature) in the sense of the consolidated version of Council Directive 67/548/EEC Annex V (Council Directive 92/69/EEC), Method A.16.

Description of key information

The temperature of the test item exceeded 400°C at a corresponding oven temperature of 356 °C.
