DIN EN 50050-3:2014-03

This European Standard specifies the requirements for hand-held or hand-operated electrostatic spraying equipment for ignitable flock 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 hazards significant for the electrostatic spraying of flock, 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-F and type B-F according to Table 1 of DIN EN 50223 (VDE 0147-103):2010. Electrostatic applicators are considered to be equipment of group II, category 3D for use in potentially explosive areas of zone 22. 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. 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.
