ATEX defines the hazards into subgroups which are defined as zones, equipment groups, gas groups, dust groups and temperature classes. The following is a definition of each. Zones– Broken into gas and dust groups. Zones 0, 1, and 2 relate to gas, and zones 20, 21, and 22 relate to dust.
A4 Basics of Explosion Protection INTRODUCTION HAZARDOUS LOCATIONS INNOVATIVE EXPLOSION PROTECTION by R. STAHL 1-800-782-4357 TEMPERATURE CLASSES Ignition temperature or auto-ignition temperature (ATI) is the minimum temperature of a surface at which an explosive atmosphere ignites.
The ATEX Directive 99/92/EC (also known as 'ATEX 137' or the 'ATEX Workplace Directive') In Europe, ATEX directive 99/92/EC sets out the minimum requirements for improving the health and safety protection of workers potentially at risk from explosive atmospheres.

The ATEX directive uses zones to classify the potential for explosion in a given environment. For example, Zone 1 and Zone 2 both relate to an explosive atmosphere formed by the presence of the key elements needed for an explosion. These are a flammable substance (such as a gas, vapor or mist), coupled with an oxidizer and a source of ignition.

Food manufacturing, where, in this case, it is the powdered milk that is combustible and when mixed with air if disturbed will ignite if an ignition source is available.. Coal handling prep plants are also considered as hazardous areas due to the concentrations of combustible coal dust clouds that can develop from spillage.. Gas wells, gas processing …
MPS mill for solid fuels and other MPS mills lies in its pressure-shock resistance. Mill and classifier housing, feed unit and expansion joints are designed pressure-shock resistant. To avoid accumulations of coal dust as a source of spontaneous combustion, all surfaces in the grinding and classifying zone are vertical or inclined.
ATEX zone 2 en ATEX zone 22 for low risk locations during normal operation ATEX zone 2 applies for a situation where the risk of a gas explosive atmosphere during normal operation is low, and the explosive atmosphere consists only rarely and for short duration. See Wikipedia's guide to writing better articles for suggestions.
For an ATEX certificate approval the areas will be divided by explosion hazard - risk zones. Place of use and zoning, as well as ignition type and protection levels are govern the requirements placed on components, units and devices. Rexroth gives you access to a wide variety of hydraulic and electric drives with ATEX certification.
Intrinsically safe circuit. A circuit in which any spark or any thermal effect produced in the conditions specified in IEC 60079‑11, including normal operation and specified fault conditions, are not capable of causing ignition of a given explosive gas atmosphere. Unlike all other protection methods intrinsic safety is the system concept, not ...
