6 0 Introduction 0.1 Process During the electrostatic coating process the non-ignitable liquid coating material is transported from a reservoir to an applicator where it is atomised by mechanical forces and by the influence of an electric field. The coating material is charged by high voltage of some 10 kV and a spray cloud is generated. The charged droplets of the coating materials are attracted by and applied to the earthed workpiece. Droplets of the coating material, which are not applied to the workpiece (overspray) are removed by a suction device or by other means. After the coating process the coated workpieces are introduced into a dryer or oven where a dry film of coating material is generated. 0.2 Fire hazards 0.2.1 Fire hazards can be caused by deposits of coating materials inside the spray booth, exhaust air ducts, the recovery system for coating materials, and filters. During operation, malfunctions or electrical faults may cause ignition of these residues. The propagation of the fire leads to hazards also in adjacent areas. 0.2.2 Particular attention should be paid to the prevention of electrostatic charges on different surfaces, which are in the vicinity of the spray cloud. This could apply both to workpieces during the coating process or the reciprocating devices and the mounting parts of the spraying system, etc. 0.2.3 When spraying non-ignitable coating material, the formation of an explosive atmosphere is not likely to occur. Electrostatic application equipment for ignitable coating materials are covered by EN 50050-1, EN 50050-2 and EN 50050-3. 0.3 Electric hazards 0.3.1 Electric shock (by direct or indirect contact) can be generated, for instance, by contact with — live parts, which are not insulated for operational reasons, — conductive parts, which are not connected to dangerous voltage during normal operation, but only in case of failure, — insulated live parts with insufficient or damaged insulation due to external impact, — charged passive parts with inadequate earthing. 0.3.2 Inadequate earthing may occur, for instance, due to — faulty connections to the protective earthing system, — a too high resistance to earth (e.g. contamination by coating materials). 0.3.3 Hazards could occur, for instance, if hazardous malfunctions (e.g. shortcut of electronic safety circuits) occur due to interferences of the electrostatic high voltage equipment and the components of the control and safety systems. 0.3.4 Hazardous electrostatic discharges could be generated, for instance, by non-earthed conductive components or by large insulating surfaces, especially if they are backed with conductive material.

Alternatively, this safety level will be reached if — the parameters specified in 4.1.1 will be limited by the diameter and the length of the material supply hose under high voltage and be limited by the maximum design short-circuit current; — the values for the outlet high voltage according to 5.4.1.1 will be limited by two Zener diodes or equivalent parts (e.g. power semiconductors) loaded up to two-thirds of the maximum rated current in the case of failure. In general, the fail-safe principle shall be applied. In case of failure of the safety functions the hand-held spraying equipment shall be led in a safe state. 4.1.17 Hand-held spraying equipment shall be equipped with an interface for the exchange of safety related signals (e.g. for interlocking with the forced ventilation of the spray booth). 4.2 Requirements for the accessories 4.2.1 Accessories shall fulfil the applicable requirements of 4.1.1. If parts of the coating material supply system do not meet this requirement, protective measures shall be taken to avoid any contact with parts under high voltage potential during normal operation. 4.2.2 Accessories to be used in spraying areas shall at least comply with the requirements of degree of protection IP54 according to EN 60529. 4.2.3 Control devices shall have a separate earth connection. 4.2.4 It shall not be possible to modify the safety-relevant operating parameters outlet high voltage and short-circuit current from the limit values tested according to 5.4.1.1 and 5.4.1.2. 4.2.5 Detachable earth connections shall be marked clearly. 4.2.6 In case conductive parts are used for coating material supply system, these parts shall be earthed according to 4.1.7, or shall be connected to the high voltage supply in such a way that their potential is per

This article discusses EN 50059:2018, which is a European Safety Standard that specifies the requirements for hand-held or hand-operated electrostatic spraying equipment used for non-ignitable liquid coating materials. The standard applies to equipment that does not create an explosive atmosphere, processes materials with a conductivity of less than 2,000 µS/cm, and operates with direct current. The standard covers electrical hazards related to electrostatic spraying, including equipment with added metal particles. The article also mentions that other hazards such as ejection of fluids, mechanical strength, electrical hazards (apart from electrostatic), noise, contact with dangerous substances, and ergonomics are covered by EN 1953. The article further provides information on quality assurance systems for electrostatic spraying equipment and mentions that additional requirements may apply for equipment used in the food and pharmaceutical industry. The article concludes by stating that the standard is not applicable to certain cases, including old equipment, cleaning of spraying areas, fire prevention and protection, and machinery for the supply and recirculation of coating material under pressure.
