Go/No-Go Dust Explosibility Screening Testing Services
Combustible dust testing is the laboratory examination of finely divided combustible particulate materials that may pose a combustion/flash-fire or explosion danger when suspended in air or another oxidizing medium. Go/No Go explosibility screening test is a type of combustion test where a material will be classed as GO (explosible) or NO GO (non-explosible) based on the results of the tests.

Overview
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.
Scope, Applications, and Benefits
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
Test Process
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).

Frequently Asked Questions
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.
