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.

Sample Requirements

Approximately 100 g of material is required.

Sample Preparation

A 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.
