- Scope
- 1.1 This European Standard specifies requirements for automatic electrostatic spraying equipmentwhich is used for spraying non-flammable liquids which do not form explosive atmospheres inThespraying area.This applies also for paints that are classed as non-ignitable while spraying, e.g. waterbased paints (see annex A).InThis connection a distinction is made between spraying devices which due toTheir type of constructioncomply with requirements of personnel protection, and those for which other discharge energies and/orcurrent limits are stipulated.It also specifies the constructional requirements forThe safe operational conditions of the electricalequipment installations including ventilation requirements. Additional requirements as toThe constructionof the spraying areas such as cabins and booths, etc. are dealt with in other standards, currently inpreparation in CEN/TC 271.NOTE If flammable liquid spraying materials are also used inThe equipment,The requirements laid down inEN 50176 for automatic electrostatic spraying equipment for flammable liquid spraying material apply; that meansthatThe spraying areas have to be equipped accordingly.1.2 This European Standard considersThe 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 InThese systemsThere 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) InThese systemsThere are dangers of electric shock.NOTE Type A systems complying with EN 50050:1986 are not relevant forThis European Standard.1.3 This European Standard considers onlyThe hazards specific toThe electrostatic characteristics ofthe electrostatic spraying process.1.4 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;whereThere are no harmonized European StandardsThen national regulations apply.
