- Executive summary:
A study was performed to determine self ignition temperature of test substance according to EU Method A.16.in compliance with GLP.
8 cm3(4.1 g) of the substance under test is placed in an oven at 27 °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.
An exotherm reaction of the test substance occurs at a temperature of about 152 °C and leads to 407 °C. After this, the temperature of the test substance overshot the oven temperature exceeded 400 °C at a temperature of 267 °C.
Under the test conditions, the relative self ignition temperature of the test substance was determined to be 267 °C.
Reference
An exothermic reaction of the test substance occurs at a temperature of about 152 °C and leads to 407 °C. After this, the temperature of the test substance overshot the oven temperature exceeded 400 °C at a temperature of 267 °C. So the relative self ignition temperature is 267 °C.
Description of key information
The relative self ignition temperature of the test substance was determined to be 267 °C.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 267 °C
Additional information

An exotherm reaction of the test substance occurs at a temperature of about 152 °C and leads to 407 °C. After this, the temperature of the test substance overshot the oven temperature exceeded 400 °C at a temperature of 267 °C.
The relative self ignition temperature of the test substance was determined to be 267 °C (Smeykal H, 1999).
