1 Cubic Meter Chamber – Characterizing Material for Dust Hazard Analysis

Posted by The Fauske Team on 08.31.17

The state of the art combustible dust testing lab at Fauske & Associates features one of only a few 1 Cubic Meter Chambers in the United States as part of its comprehensive Dust Hazard Analysis (DHA) services.  The Cubic Meter Chamber (1m3) can be used to verify testing results from the smaller 20L chamber.  The smaller size of the 20L chamber may sometimes result in what is called, “overdriving.” This is a result of the material coming in contact with the ignition source in the 20L chamber.  The Cubic Meter Chamber is not susceptible to overdriving due to its size.  The rule of thumb is to consider testing in the 1m3 when your KSt is below 50. 


Keep in mind, the amount of sample needed to conduct a test in this chamber is much larger than the 20L chamber.  Some of the tests need at least 20-30 lbs. of usable sample to complete a series of tests in the 1m3. These are generally sent to our lab in 50 lb barrels.  Tests that can be performed in the 1m3 are the Explosibility Screening Test or Challenge Test, Explosion Severity Tests - KSt Pmax, Minimum Explosibiity Concentration (MEC) and Limiting Oxygen Concentration (LOC) of your material.
