UNE-EN 50059:2018

1.1 This European Standard specifies the requirements for hand-held or hand-operated electrostatic

spraying equipment for non-ignitable liquid coating materials which

do not generate an explosive atmosphere inside the spraying area;

are used to process materials with a conductivity of less than 2000 ¼S/cm;

operate with direct current having a sinusoidal ripple of not more than 10 % of the rms value.

This European Standard deals with all electrical hazards significant for the electrostatic spraying of

ignitable 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.

This European Standard specifies the design-related and test requirements for electrostatic spraying

equipment of type A-NL according to Table 1 of EN 50348:2010.

1.2 With regard to all other significant hazards relevant for applicators (e.g. ejection of fluids, mechanical

strength, electrical (apart from electrostatic) hazards, noise, contract with or inhalation of dangerous

substances, ergonomics) the requirements of EN 1953 applies.

1.3 This European Standard also gives details regarding quality assurance systems for electrostatic

spraying equipment, see Annex D.

1.4 For electrostatic spraying equipment used in food and pharmaceutical industry, additional

requirements may apply.

1.5 This European Standard does not apply to

electrostatic hand-held spraying equipment for non-ignitable coating materials which are placed on the

market before the date of publication of this European Standard

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

fire prevention and protection [for instance fire hazards due to other sources; see EN 12215, EN 12981],

requirements for machinery for the supply and recirculation of coating material under pressure

[see EN 12621].

The requirements of EN 12621 apply for specific requirements for machinery for the supply and recirculation

of coating materials under pressure.
