Dust Testing Process

Step 1: Contact a Consultant

Tell us about your objectives with dust testing or if you need help analyzing a previous report.

Step 2: Collect and Ship

If you need dust testing, we will help you collect your dust sample and ship it to Fike’s Combustion Test Lab.

Step 3: Review Report

Once the tests are completed and you receive the report, a Fike Consultant will analyze its results with you.

Step 4: Use Results

If explosion protection is required, the test data will be used to ensure the accurate design of reliable mitigation systems.

Why Fike Dust Testing?

“The owner/operator of a facility with potentially combustible dusts shall be responsible for determining whether the materials are combustible or explosible.” - NFPA 652 (2019)

“Samples of the dust present in the equipment shall be tested and the data shall be obtained for use in the hazard identification.” - EN 1127-1 (2011)

Testing your dust is essential to complying with these standards and for the safety of your industrial process because it is used to:

Identify where dust hazards exist in your process

Design explosion protection for your unique hazards

Make process improvements to reduce the risk

Fike's Combustion Test Lab provides empirical evidence to factories, chemical plants, grain elevators, paper mills and more about the explosibility characteristics of their facility’s dust. Our testing may come in small-scale (20 liter) or world-standard large-scale (1 m3) chambers, both of which are designed to provide accurate measurements that represent real-world, industrial-sized applications.

Types of Dust Tests

We can help you choose and perform the following dust tests applicable to your process and safety goals:

Go:No Go

1. Is the dust explosive?


Screening (Go / No Go)


materials in the process susceptible to a dust explosion

how explosive

2. How explosive is the dust?


Severity (Kst & Pmax)


maximum energy and rate of an explosion if ignition occurs

where in the process

3. Where in the process may dust explosion hazards exist?


MEC - Minimum Explosible Concentration


lowest dust concentration required for ignition


LOC - Limited Oxygen Concentration


lowest oxygen concentration required to support combustion

dust combustion sensitivity

4. How sensitive is the dust to ignition?


MIE - Minimum Ignition Energy


lowest spark energy required for ignition


MIT - Minimum Ignition Temperature


lowest surface temp required for ignition


MAIT - Minimum Auto Ignition Temperature


lowest temperature of heated air required for ignition
