Minimum Auto-Ignition Temperature Testing
The Minimum Auto-Ignition Temperature (MAIT) value is used to assess a dust's sensitivity to hot surfaces, such as dryers, bearings and other mechanical parts. It helps to define explosion prevention methods.
Instrument
BAM Oven manufactured by Swissi AG of Switzerland
Applicable StandardASTM E 1491, Standard Test Method for Minimum Autoignition Temperature of Dust Clouds. This test method covers the determination of the minimum temperature at which a dust cloud will auto ignite. Sample Results
Sample RequirementsApproximately 100 g of material is required.
Sample PreparationA note on particle size and moisture level for testing. ASTM recommends that dust samples tested be made up of at least 95% minus 200 mesh (75 micron) size particles and in the dry state. However, “as-received” testing of samples is allowed. The decision on sample preparation should be based on how the data is to be used. If you are unsure which sample size/dryness level is appropriate for your application, call us at 1-844-ioKinetic to discuss. |
