TESTING SUSCEPTIBILITY OF CHARCOAL SELF-HEATING IN ACCORDANCE TO MSC 79/23/Add.4
Principle of the method.The susceptibility test for self-heating of non-activated charcoal to serve its behaviour at 140oC within 12 hours. Made of a mesh metal container, a cube with a capacity of 1dm3 is filled with charcoal and placed in a chamber preheated to a temperature of 140±2oC. During the test the temperature changes inside the sample are measured.
Stand for testing susceptibility of charcoal self-heating
- Non-activated carbon, non-activated charcoal, carbon black and lamp black fail the test if the temperature at any time during the 12 hours exceeded 200oC.
- Activated carbon and activated charcoal fail the test if the temperature at any time during the 12 hours exceeded 400oC.
One representative sample of 1 dm3 volume is subjected to the test.
