DIN EN 50223:2015-09

This European Standard specifies requirements for stationary electrostatic flock application equipment which is designed for applying ignitable flock which may form explosive atmospheres in the flock application area. For stationary electrostatic application devices for ignitable flock of type B-F, DIN EN 50050-3 (VDE 0745-103) is applicable in addition to this standard. This standard also specifies the constructional requirements for a safe operation of the stationary equipment of flock application booths, including the electrical installations and the accessories. Three types of electrostatic flock systems are considered. This standard deals with all significant hazards, hazardous situations and events relevant to flock application booths, when they are used as intended and under conditions which are foreseeable as malfunction by the manufacturer. This standard deals with those hazards occurring during stationary automatic electrostatic flocking. Among these hazards are, above all, ignition hazards of the generated explosive atmosphere and hazards to persons. The stationary equipment dealt with in this standard is considered to be equipment of group II, category 3D for the use in areas with potential explosion hazards of zone 22. The responsible committee is DKE/K 239 "Elektrostatische Sprühanlagen und -einrichtungen" ("Electrostatic painting and finishing equipment") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
