Conclusions:
The Relative Self Ignition temperature of CR SR94 was not observed  upto 400°C with 0.5°C/min heating rate.
Executive summary:

The relative self-ignition temperature for solids of CR SR94 was determined according to EC REGULATION No 440/2008 Annex A.16 Relative Self-Ignition Temperature for Solids. The test result showed that the phenomenon of self-ignition did not occur at 400°C or below.

Description of key information

The phenomenon of self-ignition did not occur at 400°C or below (EC A.16).

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
