1.1 This European Standard specifies requirements for automatic electrostatic flock application equipment which is designed for applying ignitable flock which may form explosive atmospheres in the flock application area. In this context a distinction is made between flock application devices which due to their type of construction comply with the requirements as laid down in EN 50050 as applicable, and those for which higher discharge energies are stipulated. This European 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. This European 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 (see Clause 4). 1.2 This European Standard considers four types of electrostatic flock systems. For more details, see Table 1. 1.3 This European 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 hazard to persons. 1.4 The stationary equipment dealt with in this European Standard is considered to be equipment of group II, category 3D for the use in areas with potential explosion hazards of zone 22. 1.5 In cases of hybrid mixtures, the stationary equipment dealt with in this European Standard is also considered as equipment of group II, category 3G for the use in areas with potential explosion hazard of zone 2. 1.6 This European Standard is not applicable for - flock systems operated with AC voltage, - the application system for liquid or pasty substances (e.g. adhesives, primer), - the cleaning of flock application booths, - the storage and handling of ignitable substances outside the coating plant.
