Overview

This European Standard specifies the requirements for hand-held or hand-operated electrostatic spraying equipment for ignitable coating powders within a temperature range from 5 °C to 40 °C to be used in explosive atmospheres generated by their own spray cloud. It deals with all electrical hazards significant for the electrostatic spraying of coating powders, 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-P according to Table 1 of DIN EN 50177 (VDE 147-102):2010-04. With regard to explosion protection and prevention measures, this standard also applies to ionisators with corona charging. Ionisators used together with or under similar conditions as electrostatic spraying equipment for ignitable coating powders are considered to be equipment of group II, category 2D for use in potentially explosive areas of zone 21 or 22. All other parts of ionisators are considered to be equipment of category 3D if they are installed or used in potentially explosive areas of zone 22, see Annex D. Electrostatic applicators are considered to be equipment of group II, category 2D for use in potentially explosive areas of zone 21 or 22, which have been generated by the equipment itself. All other parts of hand-held electrostatic spraying equipment are considered to be equipment of category 3D if they are installed or used in potentially explosive areas of zone 22, see Annex D. This European Standard also gives more detailed information regarding quality assurance systems for electrostatic spraying equipment, see Annex C. Additional requirements may be applicable to electrostatic spraying equipment designed for use in food and pharmaceutical industry. The responsible body is DKE/K 239 "Elektrostatische Sprühanlagen und -einrichtungen" ("Electrostatic spraying equipment") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
