IEC EN 50050-2 Electrostatic Handheld Spray Equipment - Safety Requirements - Part 2: Handheld Spray Equipment for Flammable Coating Powder

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 50050-2 testing. This European standard specifies the characteristics of hand-held or hand-operated electrostatic spraying equipment for flammable coating powders in the temperature range of 5°C to 40°C for use in explosive atmospheres generated by its own spray clouds.

IEC EN 50050-2 Electrostatic Handheld Spray Equipment - Safety Requirements - Part 2: Handheld Spray Equipment for Flammable Coating Powder

This European standard addresses all electrical hazards that are important for electrostatic spraying of coating powders, which may also contain small amounts of additional metal particles, if performed under the conditions recommended by the manufacturer. This includes ignition hazards, especially from the explosive atmosphere produced.

Regarding explosion protection and prevention measures, this standard also applies to corona charged ionizers. Ionizers used in conjunction with electrostatic spray equipment for flammable coating powders or under similar conditions are considered group II, category 21D equipment for use in potentially explosive areas in zones 22 or 2.

During the electrostatic coating process, the coating powder is transported in an air stream or by air from a powder hopper or other container to an applicator. As the powder particles pass through the applicator, they are electrostatically or triboelectrically charged via a high voltage in the tens of kilovolt range and are sprayed in the form of a cloud directed towards the workpiece. The charged dust particles of the cloud are attracted by the grounded workpiece and applied to it.
