What is BS EN 50059 - non-ignitable electrostatic spraying equipment safety about?
Coating over surfaces protects substrates from corrosion and overspray. During the electrostatic coating process, the non-ignitable liquid coating material is transported from a reservoir to an applicator where it is atomised by mechanical forces and by the influence of an electric field. The coating material is charged by a high voltage of some 10 kV and a spray cloud is generated. The charged droplets of the coating materials are attracted by and applied to the earthed workpiece.
BS EN 50059 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 2 000 μS/cm
- Operate with direct current having a sinusoidal ripple of not more than 10 % of the RMS value
BS EN 50059 deals with all electrical hazards significant for the electrostatic spraying of non-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.
Who is BS EN 50059 - non-ignitable electrostatic spraying equipment safety for?
BS EN 50059 on non-ignitable electrostatic spraying equipment safety is useful for:
- Manufacturers of electrostatic hand-held spraying equipment for non-ignitable coating materials
- Owners and operators of coating plants - Spray booths
- Quality assurance teams for electrostatic spraying equipment
- Product development teams
Why should you use BS EN 50059 - non-ignitable electrostatic spraying equipment safety?
A coating applied with an electrostatic spray gun may help prevent or reduce corrosion in a more efficient manner than a conventional spray coating method. An electrostatic spray gun is a device used to spray paint onto a substrate while using charged molecules and electric fields.
BS EN 50059 discusses general tests, conditioning tests, tests for electrical safety and also tests for accessories in detail. The section on Requirements for hand-held spraying equipment for non-ignitable liquid coating materials enumerates general requirements as well as requirements for accessories in BS EN 50059.
Using BS EN 50059 guidelines, you would be able to determine the ideal working standards with electrostatic hand-held spraying equipment, so that you can provide users and operators with a safe atmosphere along with avoiding all sorts of hazards including fire and electrical hazards.
