What Is Go No Go Dust Explosibility Screening?
The Go/No-Go Explosibility Screening Test is a preliminary safety test that helps determine if a material has the potential to explode when it comes into contact with ignition sources under certain conditions. This test is usually conducted on powders, chemicals, and dusts before full explosibility tests are carried out.
The Go/No-Go Explosibility Screening Test helps laboratories and industries quickly determine whether a material poses an explosion hazard.
Applications and Benefits of Go No Go Dust Explosibility Screening Testing
Scope
The Go/No-Go screening test evaluates whether a dust or powdered material can produce an explosive reaction in the presence of an ignition source under controlled laboratory conditions.
It provides an initial assessment of explosion risk and helps determine whether more detailed explosibility testing is required.
The scope includes:
Screening of combustible dusts and powders
Identification of potential explosion hazards
Preliminary laboratory explosibility assessment
Evaluation under controlled ignition conditions
Safety assessment before detailed explosion testing
Applications
Chemical industries
Powder handling and processing industries
Food and agricultural dust safety evaluation
Industrial dust hazard assessment
Process safety and risk evaluation
Benefits
Provides rapid explosibility screening
Helps identify hazardous dust materials
Improves workplace safety in powder handling
Determines the need for further explosion testing
Supports industrial safety and hazard prevention
Our Testing Procedure
Sample Preparation
A measured quantity of powdered material is prepared and placed in the test chamber.
1Dust Dispersion
The sample is dispersed into the test chamber to create a dust cloud under controlled conditions.
2Ignition Source Application
A controlled ignition source is introduced to the dust cloud.
3Explosion Observation
The reaction is observed to determine whether ignition leads to an explosion (Go) or no explosion (No-Go).

Go No Go Dust Explosibility Screening FAQs
It is a preliminary test used to determine whether a powdered material can cause an explosion when exposed to an ignition source.
The test helps identify potential explosion hazards in powders and dusts, improving industrial safety and preventing accidents.
No, a No-Go result only indicates that the material did not explode under specific test conditions. Additional testing may still be required.
If a Go result occurs, further detailed tests such as dust explosion severity testing and minimum ignition energy tests may be conducted.
Factors include particle size, dust concentration, moisture content, oxygen level, and ignition energy.
Go/no-go explosibility screening evaluates whether a combustible powder or dust can ignite and propagate an explosion under specified test conditions. A prepared sample is exposed to a controlled ignition source in a suitable test apparatus, and the resulting pressure or combustion response is assessed. The results help determine whether further dust explosion testing is needed for process safety evaluation.
Explosion testing evaluates how a material or dust cloud responds to ignition under controlled laboratory conditions. Depending on the test objective, measurements may include maximum explosion pressure, rate of pressure rise, explosibility, and minimum ignition energy. These results help assess fire and explosion hazards and support the selection of appropriate industrial safety measures.
An explosive dust test determines whether a powder can ignite and propagate a flame or explosion when dispersed in air. A representative sample is tested in specialized laboratory equipment under controlled conditions. Depending on the test, measurements may include maximum explosion pressure (Pmax), maximum rate of pressure rise, and the deflagration index (Kst). ASTM E1226 is commonly used to evaluate dust-cloud explosibility and explosion severity.
