- Executive summary:
The purpose of the test was the determination of the relative self-ignition temperature according to Guideline 92/69/EEC Part A. 16. Auto-flammability (solids-determination of relative self-ignition temperature). Study conducted in compliance with GLP.
8 cm3 (4.35 g) of the substance under testisplaced in an oven at 26 °C ; the temperature/time curve relating to conditions in the centre of the sample is recorded while the temperature of the oven is 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 exotherm reaction of the test substance occurs at a temperature of 175 °C and leads to 335 °C. After this, the temperature of the test substance was permanent over the oven temperature until the maximum temperature of 404 °C.
No self ignition was registered until a temperature of 404 °C.
Reference
An exotherm reaction of the test substance occurs at a temperature of 175 °C and leads to 335 °C. After this, the temperature of the test substance was permanent over the oven temperature until the maximum temperature of 404 °C.
Description of key information
