1.1 This European Standard specifies the requirements for hand-held or hand-operated electrostatic spraying equipment for ignitable coating powders 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 coating powders, 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-P according to Table 1 of EN 50177:2009.

1.2 With regard to explosion protection and prevention measures, this standard also applies to ionisators with corona charging. Ionisators used together with or under similar conditions as electrostatic spraying equipment for ignitable coating powders are considered to be equipment of group II, category 2D for use in potentially explosive areas of zone 21 or 22. All other parts of ionisators are considered to be equipment of category 3D if they are installed or used in potentially explosive areas of zone 22, see Annex D.

1.3 Electrostatic applicators are considered to be equipment of group II, category 2D for use in potentially explosive areas of zone 21 or 22, which have been generated by the equipment itself. 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.

1.4 All other significant hazards relevant for applicators (e.g. ejection of powder, mechanical strength, electrical hazards (apart from the electrostatic hazards)), noise, explosion, contract with or inhalation of dangerous substances, ergonomics) are covered by EN 1953.

1.5 This European Standard also gives details regarding quality assurance systems for electrostatic spraying equipment, see Annex C.

1.6 Additional requirements may be applicable to equipment designed for use in food and pharmaceutical industry.

1.7 This European Standard does not apply to

  • zone classification of the areas in and around spray booths [see EN 12981],

  • 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 12981],

  • cleaning of spraying areas, see instruction manual of the spray booth,

  • fire prevention and protection, for instance fire hazards due to other sources [see EN 12981],

  • dust hazards [see EN 12981].
