Anotation

This document specifies the electrical requirements for hand-held or hand-operated electrostatic application equipment for non-ignitable liquid coating materials which
- do not generate an explosive atmosphere inside the spraying area,
- are used to process coating materials with a conductivity of the complete system up to 2 000 µS/cm,
- operate with direct current having a d.c. sinusoidal ripple of not more than 10 % of the r.m.s. value, and
- are used within a temperature range from 5 °C to 40 °C.
1.2 This document specifies
- requirements for an interface to machinery according to EN 16985:2018,
- additional requirements for machinery according to EN 1953:2025 and EN 12621:2025.
1.3 This document also specifies requirements for a safe operation of electrostatic application equipment, including the electrical installation. The requirements consider both the processing of coating materials and the cleaning and purge processes.
1.4 For electrostatic application equipment used in food and pharmaceutical industry, additional requirements can apply.
1.5 This document does not apply to
- electrostatic hand-held spraying equipment for ignitable materials, see EN 50050:2013, Parts 1 to 3,
- cleaning systems for spraying devices,
- quality assurance systems for electrostatic spraying equipment (see EN ISO/IEC 80079-34:2020, Clause ZB.11)
