Micro Combustion Calorimeter
ASTM D 7309
The Micro Combustion Calorimeter was developed by the Federal Aviation Administration (FAA) to offer industry a research tool to assist the FAA in its mandate to dramatically improve the fire safety of aircraft materials.
The tester is becoming a mainstay in research laboratories due to its ability to obtain meaningful test data with a sample size in the range of 0.5 Mg to 50 mg. The instrument has been validated by a national consensus organisation ASTM International and is now the subject of an ASTM standards publication, designated D7309. Micro Combustion Calorimetry (MCC), sometimes referred to as Pyrolysis-Combustion Flow Calorimetry (PCFC), measures the rate at which the heat of combustion of fuel gases are released by a solid during controlled pyrolysis in an inert gas stream. The fuel gases are mixed with excess oxygen and combusted (oxidised) at high temperature, and the instantaneous heat of combustion of the flowing gas stream is measured by oxygen consumption calorimetry.

The new flammability test method quickly and easily measures the combustibility of plastics, wood and textiles etc. Only a few milligrams of sample are needed and results are obtained in minutes, instead of hours or days of analysis. The test apparatus shown above, provides a wealth of information on the fire hazard of a material. View the downloadable data sheet for more information.
