  Description:

Electrostatic hand-held spraying equipment - Safety requirements - Part 3: Hand-held spraying equipment for ignitable flock

  Purpose

1.1 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. This European Standard deals with all electrical 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 EN 50223:2010. 1.2 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. NOTE 1 Solvent vapours which could be evaporated by workpieces coated with adhesives do not lead to a zone 2 in the flocking area. 1.3 In addition to the requirements above, the requirements of EN 1953 applies with regard to all other significant hazards relevant for applicators (e.g. health hazards, inadequate ergonomics). 1.4 This European Standard does not apply to  zone classification of the areas in and around spray booths [see EN 50223],  zone classification of other areas with potentially explosive atmosphere [see EN 60079-10-2],  selection, erection and application of other electrical and non-electrical equipment in areas with explosion hazard [see EN 60079 14 and EN 50223],  cleaning of spraying areas, see instruction manual of the spraying equipment,  fire prevention and protection, for instance fire hazards due to other sources [see EN 50223],  explosion protection systems [see EN 50223],  dust hazards [see EN 12981]. NOTE 2 Noise is not considered to be a significant hazard for hand-held spraying equipment for ignitable flock.
