scope:

This European Standard specifies requirements for automatic electrostatic spraying equipment which are used for spraying flammable powders which create explosive atmospheres in the spraying area. In this connection distinction is made between spraying devices which due to their type of construction comply with requirements as laid down in EN 50050:2006 as applicable, and those for which other discharge energies and/or current limits are stipulated. It also gives information on the safe operational conditions of the electrical equipment including ventilation requirements. Additional requirements as to the construction of the spraying areas such as cabins, booths, etc. are dealt with in EN 12981.
