GLP compliance:
Key result
Relative self-ignition temperature:
> 220 °C

1) It can be considered as an endothermic effect from the sample melting, that Oven temperature was a little higher than Sample Temperature when the sample was heated to its melting point.

2) There was no substance in the vessel after the test completed; this could be proved that the sample in the vessel had melted and flowed away from the cribriform vessel.

3) The sample temperature could not reach 400℃ prior to that of the oven until it was heated to its melting point; it could be confirmed that the relative self-ignition temperature was above the melting point.

The relative self-ignition temperature of the sample (EC: 254-935-6:) is above its melting point.
Executive summary:

In this guideline (EC Regulation No.440/2008 - Annex A.16) study conducted with GLP certification, the auto flammability temperature of the test material (EC 254-935-6) was determined above its melting point.

Description of key information

The relative self-ignition temperature of the sample is above its melting point.

Key value for chemical safety assessment
