ATEX is the conventional name of the Directive 2014/34 EU for the equipment intended for use in potentially explosive atmospheres.
It imposes the evaluation of the risk for all the equipment operating in such environments.
It classifies several levels of "danger" (zones): to every zone it corresponds a different typology of explosive atmosphere, according to its composition and to its probability and time of appearance.
Motive gearboxes series (BOX-EX, ROBUS-EX, ENDURO-EX, STON-EX e STADIO-EX) are certified according to the norms EN ISO/IEC 80079-36, EN ISO/IEC 80079-37, EN 1127-1 for the zones 1, 21, 2 and 22
| Cat | DUST | GAS | Zone | Description | motive gearboxes |
| 1 | yes | 0 | A place in which an explosive atmosphere consisting of a mixture with air of flammable substances in the form of gas, vapor or mist is present continuously or for long periods or frequently. | ||
| 2 | 1 | A place in which an explosive atmosphere consisting of a mixture with air or flammable substances in the form of gas, vapor or mist is likely to occur in normal operation occasionally | yes | ||
| 3 | 2 | A place in which an explosive atmosphere consisting of a mixture with air of flammable substances in the form of gas, vapor or mist is not likely to occur in normal operation but, if it does occur, will persist for a short period only | yes | ||
| 1 | yes | 20 | A place in which an explosive atmosphere in the form of a cloud of combustible dust in air is present continuously, or for long periods or frequently | ||
| 2 | 21 | A place in which an explosive atmosphere in the form of a cloud of combustible dust in air is likely to occur in normal operation occasionally. | yes | ||
| 3 | 22 | A place in which an explosive atmosphere in the form of a cloud of combustible dust in air is not likely to occur in normal operation but, if it does occur, will persist for a short period only. | yes |
