ATEX is the name commonly given to the two European Directives for controlling explosive atmospheres: 1) Directive 99/92/EC (also known as 'ATEX 137' or the 'ATEX Workplace Directive') on minimum requirements for improving the health and safety protection of workers potentially at risk from explosive atmospheres.
The Minimum Ignition Energy MIE is very important for dust explosion risks analysis, it will show how easy a dust cloud can be ignited. The MIE is equal to the minimal energy needed to be brought by a spark to a dust cloud of a given concentration in order to ignite it following a specific experimental procedure [Laurent]. 2.
Dusts are split into Groups based on dust types rather than Ignition energy as generally dust has approximately 1000 times the minimum ignition energy than gases do. Therefore ignition energy becomes largely irrelevant in terms of Atex certifiion as most protection techniques were devised around the lower ignition levels for gases and dust type becomes the important factor in the risk ...
