It takes three things to start a fire: oxygen, \"\"fuel, and ignition. Unless you\u2019re in a controlled atmosphere, there\u2019s always plenty of oxygen in the air around us. And in many industrial settings, fuel\u2014flammable gas or liquid or finely divided flammable powders or fibers\u2014is readily available in the products they make or use. Such operations go to great lengths to contain these dangerous fuels, but the critical factor that must be controlled is sources of ignition. For suppliers and users of electrical components, that means a spark or a hot surface.<\/p>\n

ATEX and IECEx standards govern equipment used in explosive atmospheres, with ATEX being a European Union directive and IECEx standard followed worldwide. At this time, both directives still incorporate the \u201cEx nA\u201d protection concept for non-sparking electrical devices being used in Zone 2 hazardous areas. The recent release of IEC 60079-7:2015 introduces \u201cEx ec\u201d protection concept as a replacement for \u201cEx nA\u201d. The actual replacement will fully take place at some time in the future. This will not affect the construction or operation of the products Minco provides, but it will affect the way they need to be designated by users purchasing equipment for use in these areas. In other words, at some time in the future, if you use the old designation your specification will be returned to you for correction. Here\u2019s what you need to know:<\/p>\n
