Flammability tests are difficult because of the complexity of burning processes and of safety considerations. Experimental fires only give a partial view of the combustion process. Owing to the dynamic processes occurring in the flame, tests are very sensitive to external influences. Use, therefore, of flammability test methods should be made only with a clear understanding of what is being tested. Only officially standardized and recognized test methods should be sued.
