This test is used to determine the explosibility of a combustible dust-air mixture. It is one of two screening tests listed in NFPA 652.

Applicable Standard

ASTM E 1226 Standard Test Method for Explosibility of Dust Clouds. The methods of this standard can be used to determine if a dispersed dust cloud is "explosible" and, if so, to what degree it is explosible, i.e., its "explosibility".

Sample Requirements

Approximately 200g of material is required.

Sample Preparation

ASTM recommends that dust samples tested be made up of at least 95% minus 200 mesh size particles and less than 5% moisture content. However, "as-received" testing of samples is allowed. The decision on sample preparation should be based on how the data is to be used.
