Gases and vapours
We do a range of testing (to national and international standards) on products to certify them as safe to use in environments containing potentially explosive hazardous gases and vapours.
Pressurised enclosure tests are carried out to determine if the pressurised enclosure of the electrical equipment can prevent explosive gases or dusts from entering and coming into contact with live parts or hot surfaces.
Powder filling testing
Powder filling ‘Ex q’ tests are carried out to determine if the powder used inside the electrical equipment is capable of preventing an ignition of an explosive gas within the equipment from spreading through the powder to an explosive gas atmosphere surrounding the equipment.
Flamproof enclosure testing
Flameproof enclosure ‘Ex d’ tests are carried out to determine if the flameproof enclosure of the electrical equipment is capable of preventing an explosion within the equipment from spreading to the outside of the equipment.
Oil immersion testing determines if the protective liquid in which the electrical equipment is immersed can prevent an explosive gas atmosphere from coming into contact with live parts.
Increased safety 'Ex e' testing
Increased safety tests determine if the design of the electrical equipment prevents arcs, spark and hot surfaces from occurring within the equipment.
Intrinsic safety testing
Intrinsic safety ‘Ex i’ assessment and test is carried out to analyse whether each circuit in which spark or any thermal effect produced or electrical energy stored in normal operation and specified fault conditions, is capable of causing ignition of a given explosive atmosphere or not.
Non-sparking 'Ex n' tests determine if the design of the electrical equipment prevents any potential sources of ignition.
Encapsulation ‘Ex m’ tests determine if the encapsulation method used in the design of the electrical equipment to enclose either sparking or heating parts in a compound prevent ignition of an explosive gases or vapours or dust.
