scope:

This European Standard specifies the requirements for hand-held or hand-operated electrostatic spraying equipment for ignitable liquid coating materials to be used in explosive atmospheres generated by their own spray cloud within a temperature range from 5 °C to 40 °C. This European Standard deals with all hazards significant for the electrostatic spraying of liquid coating materials, which could also contain small quantities of added metal particles, if the work is carried out under conditions recommended by the manufacturer. In particular, this includes ignition hazards resulting from the generated explosive atmosphere. This European Standard specifies the design-related and test requirements for electrostatic spraying equipment of type A-L according to Table 1 of EN 50176:2009. With regard to explosion protection and prevention measures, this European Standard also applies to ionisators with high voltage corona charging. Ionisators in conformity with EN 50050-1 provide equipment category 2G. Parts of ionisators, which are intended to be used or installed in Zone 2, provide equipment category 3G in conformity with EN 50050-1:2013.Electrostatic applicators are considered to be equipment of group II, category 2G for use in potentially explosive areas of zone 1 or 2, which have been generated by the equipment itself. All other parts of hand-held electrostatic spraying equipment are considered to be equipment of category 3G if they are installed or used in potentially explosive areas of zone 2. All other significant hazards relevant for applicators (e.g. ejection of fluids, mechanical strength, electrical hazards (apart from the electrostatic hazards), noise, explosion, contact with or inhalation of dangerous substances, ergonomics) are covered by EN 1953.This European Standard also gives details regarding quality assurance systems for electrostatic spraying equipment. Additional requirements may be applicable to equipment designed for use in food and pharmaceutical industry.
