Reference
Observations after the test:
The cube was full of a beige powder.
Key result:
The test material has been determined not to have a relative self-ignition temperature below 400 °C.
The temperature/time curve is presented as an attached illustration.
Description of key information
The test material showed no relative self-ignition temperature below 400 °C (study result, EU A.16 method).
Key value for chemical safety assessment
Additional information
The test material showed no relative self-ignition temperature below 400 °C.Calcium carbonate was also found to be not auto flammable in a study performed using Method N.4 of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, 4th revised edition, 2003. On this basis it may be concluded that grades of calcium oxide containing up to 35% calcium carbonate will not be auto flammable.
