ASTM D7309: Standard Test Method for Determining Flammability Characteristics of Plastics and Other Solid Materials Using Microscale Combustion Calorimetry
The Micro Calorimeter was developed in co-operation with the Federal Aviation Administration (FAA). It determines fundamental thermo-chemical data in seconds and predicts fire properties of materials.
The technique enables parameters such as Specific Heat Release Rate (W/g), Heat of Combustion (J/g) and Ignition Temperature (°C) to be quickly determined from very small (1-5mg) specimens. It is a low cost and accurate technique; typical repeatability is ± 5%.
Micro Calorimeter data has been shown to correlate with fire test data (Cone Calorimeter, OSU), flammability results (LOI, UL94) and combustion tests (Bomb Calorimeter) and is therefore seen as a powerful, low-cost tool to assess and predict flammability properties.
