1.1

This European Standard specifies the requirements for hand-held or hand-operated electrostatic spraying equipment for ignitable liquid coating materials to be used in explosive atmospheres generated by their own spray cloud within a temperature range from 5°C to 40°C.

This European Standard deals with all hazards significant for the electrostatic spraying of liquid coating materials, 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-L according to Table1 of EN50176:2009.

1.2

With regard to explosion protection and prevention measures, this European Standard also applies to ionisators with high voltage corona charging. Ionisators in conformity with EN50050-1 provide equipment category2G. Parts of ionisators, which are intended to be used or installed in Zone 2, provide equipment category3G in conformity with EN50050-1:2013, see Annex D.

1.3

Electrostatic applicators are considered to be equipment of group II, category2G for use in potentially explosive areas of zone 1 or 2, which have been generated by the equipment itself. All other parts of hand-held electrostatic spraying equipment are considered to be equipment of category3G if they are installed or used in potentially explosive areas of zone 2.

1.4

All other significant hazards relevant for applicators (e.g. ejection of fluids, mechanical strength, electrical hazards (apart from the electrostatic hazards), noise, explosion, contact with or inhalation of dangerous substances, ergonomics) are covered by EN1953.

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 EN12215],

  • zone classification of other areas with potentially explosive atmosphere [see EN60079-10-1],

  • selection, erection and application of other electrical and non-electrical equipment in areas with explosion hazard [see EN60079-14 and EN12215],

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

  • Fire prevention and protection, for instance fire hazards due to other sources [see EN12215],

  • requirements for machinery for the supply and recirculation of coating material under pressure [see EN12621].

1.8

When processing coating materials having specific electrical properties (conductivity, resistivity) the function of the hand-held spraying equipment to charge coating materials electrostatically may be affected as a result of a voltage drop at the charging electrode.
