Room temperature:      19 to 21 °C
Atmospheric pressure: 100.65 to 101.68 kPa

Conclusions:
The test material has been determined to have an auto-ignition temperature of 350 ± 5 °C.
Executive summary:

The auto-ignition temperature was determined by heating aliquots of the test material in a flask and observing for any ignition. Testing was conducted using Method A.15 of Commission Directive 92/69/EEC (which constitutes Annex V of Council Directive 67/548/EEC).

The test material has been determined to have an auto-ignition temperature of 350 ± 5 °C (at a room temperature of 19 to 21 °C and an atmospheric pressure of between 100.65 and 101.68 kPa).

Description of key information

auto-ignition temperature of the test material (determined using EU Method A.15): 350 ± 5°C (at a room temperature of 19 to 21 °C and an atmospheric pressure of between 100.65 and 101.68 kPa)

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
345 °C
