Scope

1 This European Standard specifies requirements for automatic electrostatic spraying equipment which is used for spraying non-flammable liquids which do not form explosive atmospheres in the spraying area. This applies also for paints that are classed as non-ignitable while spraying, e.g. water based paints (see annex A). In this connection a distinction is made between spraying devices which due to their type of construction comply with requirements of personnel protection, and those for which other discharge energies and/or current limits are stipulated. It also specifies the constructional requirements for the safe operational conditions of the electrical equipment installations including ventilation requirements. Additional requirements as to the construction of the spraying areas such as cabins and booths, etc. are dealt with in other standards, currently in preparation in CEN/TC 271. NOTE If flammable liquid spraying materials are also used in the equipment, the requirements laid down in EN 50176 for automatic electrostatic spraying equipment for flammable liquid spraying material apply; that means that the spraying areas have to be equipped accordingly. 2 This European Standard considers the following types of electrostatic spraying systems: Type B Systems with a discharge energy limit in excess of 5 mJ but less than 350 mJ and a current limit of less than 0,7 mA In these systems there is no danger of electric shock. Type C Systems with a discharge energy in excess of 350 mJ and/or a current in excess of 0,7 mA (see 5.1.2) In these systems there are dangers of electric shock. NOTE Type A systems complying with EN 50050:1986 are not relevant for this European Standard. 3 This European Standard considers only the hazards specific to the electrostatic characteristics of the electrostatic spraying process. 4 For other aspects, such as: - selection, installation and use of electrical equipment in hazardous areas; - health hazards, for example toxic and skin effects; - cleaning of spraying areas; - fire hazard from external sources; - fire protection; where there are no harmonized European Standards then national regulations apply.
