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

We will help guide you to collect your dust sample and ship it to Fike’s Combustion Test Lab.

Step 3: Review Report

Once you receive the Dust Test Report, your Fike Consultant will analyze its results with you.

Step 4: Use Results

The data is used to define the explosion protection strategy and design a mitigation approach.

Do you have any questions about dust testing, such as, When are certain tests required? How is the data used to prevent explosions? Or how is a dust sample collected and shipped? We recently answered these questions and many more in our new Fike Dust Testing Booklet!

Using Dust Testing to Reduce the Risk of Combustion

Did you know that by testing the dust handled in your facility, simple safety improvements may be made to reduce the risk of an explosion?

Fike offers a variety of "sensitivity tests" that identify various conditions in which your dust may ignite. For example, a Minimum Ignition Temperature of a Layer test measures the lowest surface temperature required to ignite a layer of dust. This data can be used to both monitor and mitigate the hot surfaces within your process to ensure they remain under the dust's MIT.

This is just one example of how a Fike consultant will meet with you to review the results of your Dust Test Report and identify preventative measures to improve the safety in your facility.

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 (Pmax & Kst)


maximum pressure and rate of pressure rise of an explosion

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 - Limiting 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


MIT (LAYER) - Minimum Ignition Temperature of a Dust Layer


lowest temperature in which a layer of dust will ignite


MIT (Cloud) - Minimum Ignition Temperature of a Dust Cloud


lowest temperature in which a dust cloud will ignite
