Understanding ATEX and IECEx Certification for Mobile Devices in Hazardous Areas
If you work in oil and gas, chemical processing, or pharmaceutical manufacturing, you know that not every piece of equipment belongs on the plant floor. Consumer electronics, including smartphones, can become ignition sources in areas where flammable gases, vapors, or dust are present. What Is Intrinsic Safety? Intrinsic safety (IS) is a protection method that limits the electrical and thermal energy in a circuit so it cannot cause ignition of a hazardous atmosphere. Unlike other methods that contain an explosion after it happens, IS prevents ignition in the first place. The two main certification frameworks are ATEX (European Directive 2014/34/EU), mandatory within the EU/EEA, and IECEx (International Electrotechnical Commission), recognized in over 30 countries worldwide. Zone Classification Hazardous areas are divided into zones based on how likely an explosive atmosphere is to be present. Zone 0 means continuous presence, Zone 1 means likely during normal operations, an...
