Self-heating MSC 79/23/Add.4
Laboratory
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
Results
- 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.
Test samples.
One representative sample of 1 dm3 volume is subjected to the test.
