Conclusions:
Blendazol Red Blendwell is consiered as auto-flammable with a Relative Self Ignition Temperature of 265.5 °C
Executive summary:

 the Relative Self Ignition Temperature of Blendazol Red was determined using Wire Mesh Cube according to EU-Method A.16

The temperature of the test substance had reached 400°C according to EU-Method A.16 at the oven temperature of 265.5 °C.

Therefore, the test substance Blendazol Red Blendwell is considered as auto-flammable under the test conditions with a Relative Self Ignition Temperature of 265.5 °C
