CLC/TC 204 - Safety of electrostatic painting and finishing equipment

1.1 This European Standard specifies the requirements for hand-held or hand-operated electrostatic spraying equipment for non-ignitable liquid coating materials which — do not generate an explosive atmosphere inside the spraying area; — are used to process materials with a conductivity of less than 2 000 µS/cm; — operate with direct current having a sinusoidal ripple of not more than 10 % of the rms value. This European Standard deals with all electrical hazards significant for the electrostatic spraying of non-ignitable 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. This European Standard specifies the design-related and test requirements for electrostatic spraying equipment of type A-NL according to Table 1 of EN 50348:2010. 1.2 With regard to all other significant hazards relevant for applicators (e.g. ejection of fluids, mechanical strength, electrical - apart from electrostatic - hazards, noise, contact with or inhalation of dangerous substances, ergonomics) the requirements of EN 1953 apply. 1.3 This European Standard also gives details regarding quality assurance systems for electrostatic spraying equipment, see Annex D. 1.4 For electrostatic spraying equipment used in food and pharmaceutical industry, additional requirements may apply. 1.5 This document is not applicable to — electrostatic hand-held spraying equipment for non-ignitable coating materials which are manufactured before the date of its publication as EN, — cleaning of spraying areas, see instruction manual of the spraying booth, — fire prevention and protection [for instance fire hazards due to other sources; see EN 12215, EN 12981], — requirements for machinery for the supply and recirculation of coating material under pressure [see EN 12621]. The requirements of EN 12621 apply for specific requirements for machinery for the supply and recirculation of coating materials under pressure.

1.1 This European Standard specifies the requirements for stationary electrostatic application equipment for non-ignitable liquid coating materials which do not generate an explosive atmosphere inside the spraying area. A distinction is made between spraying systems corresponding to EN 50050 and spraying systems designed for higher discharge energies and/or currents. This European Standard also specifies the design-related requirements for a safe operation of the stationary equipment, including its electrical installations. 1.2 This European Standard considers two types of electrostatic spraying systems, see 5.1 for more details. 1.3 Noise has not been dealt with in this standard as it is not considered to be a significant hazard of stationary electrostatic application equipment for non-ignitable liquid coating material. For any other health protection, see EN 12215:2004, 5.5. For fire prevention and protection (e. g. fire hazards due to other sources), see also EN 12215:2004, 5.7.1. This European Standard deals with all significant hazards, hazardous situations and events, which are relevant for stationary electrostatic application equipment for non-ignitable liquid coating and cleaning materials which do not generate an explosive atmosphere inside the spraying area, provided they are used as intended by the manufacturer.

This work item will specify the requirements for hand-held or hand-operated electrostatic spraying equipment for non-ignitable coating materials which do not generate an explosive atmosphere inside the spraying area. It will deal with all hazards significant for the electrostatic spraying of non-ignitable coating materials, which could also contain small quantities of added metal particles, if the work is carried out under conditions recommended by the manufacturer. It will not apply to: - cleaning of spraying areas, see instruction manual of the spraying booth; - fire prevention and protection [for instance fire hazards due to other sources.

This European Standard specifies the constructional and test requirements for hand-held and hand-operated electrostatic spray guns and associated apparatus used to spray painting and finishing materials which are not flammable, with respect to the protection against high voltage electric shock. Note: the requirements for electrostatic hand-held spray guns and associated apparatus which are only to be used for flammable spraying materials are covered in European standard EN 50 050
