Overview

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. It 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 standard specifies the design-related and test requirements for electrostatic spraying equipment of type A-L according to Table 1 of DIN EN 50176 (VDE 0147-101):2010-04. With regard to explosion protection and prevention measures, this standard also applies to ionisators with high voltage corona charging. Ionisators in conformity with DIN EN 50050-1 (VDE 0745-101):2014-03 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 DIN EN 50050-1 (VDE 0745-101):2014-03, see Annex D. 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. This European Standard also gives details 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.
