Understanding combustible dust testing cost is an important part of planning a DSEAR risk assessment or reviewing combustible dust hazards. While testing represents an additional investment, obtaining accurate dust explosion data helps ensure that risk assessments and hazardous area classifications are based on reliable technical information. As discussed in our article here, sometimes you can rely on published data, but often dust testing is required to get accurate data for your operations.
The overall cost depends on the type and number of tests required, as well as the properties of the dust being assessed.
What affects combustible dust testing cost?
The cost of combustible dust testing varies depending on the explosion characteristics that need to be determined.
Rather than requesting every available test, it is generally best to discuss your process with a competent combustible dust testing laboratory. They can recommend the most appropriate testing programme based on your materials, process and assessment objectives.
How much does combustible dust testing cost in the UK?
Although prices vary between laboratories, typical UK costs are:
- Basic explosibility screening test: approximately £300-500
- Individual dust explosion property tests: approximately £500-800 per test
- Complete suite of combustible dust tests: typically £2,000–£4,000
A basic explosibility screening test determines whether your dust is capable of forming a flammable dust cloud in air. Additional testing can then establish important explosion characteristics required for DSEAR risk assessments and explosion protection design.
How much dust is required for testing?
The quantity of dust needed depends on the number and type of tests being carried out.
As a guide, laboratories may require anywhere between 500 g and 2 kg of representative dust samples.
Providing a representative sample is important, as the test results will be used to assess the explosion hazards associated with your specific process.
How do you know which dust tests are required?
Not every workplace requires the same testing programme.
The appropriate tests depend on factors such as:
- the type of dust being handled
- how the dust is processed
- whether combustible dust clouds or layers may form
- the information already available for the material
- the requirements of your DSEAR risk assessment or Hazardous Area Classification
An experienced process safety consultant or specialist testing laboratory can help determine the most appropriate testing strategy.
