What is BS EN 50050-2 - Safety requirements hand-held spraying equipment about?
BS EN 50050-2 discusses electrostatic hand-held spraying equipment. BS EN 50050-2 is the second part of the BS EN 50050 series of standards that specifies the requirements for hand-held or hand-operated electrostatic spraying equipment for ignitable coating powders within a temperature range from 5 °C to 40 °C to be used in explosive atmospheres generated by their own spray cloud.
BS EN 50050-2 deals with all electrical hazards significant for the electrostatic spraying of coating powders, 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. BS EN 50050-2 specifies the design-related and test requirements for electrostatic spraying equipment of type A-P. BS EN 50050-2 also gives details regarding quality assurance systems for electrostatic spraying equipment.
Note: BS EN 50050-2 does not apply to:
- Zone classification of the areas in and around spray booths [see EN 12981]
- Zone classification of other areas with potentially explosive atmosphere [see EN 60079-10-2]
- Selection, erection and application of other electrical and non-electrical equipment in areas with explosion hazard [see EN 60079-14 and EN 12981]
- Cleaning of spraying areas, see instruction manual of the spray booth
- Fire prevention and protection, for instance fire hazards due to other sources [see EN 12981]
- Dust hazards [see EN 12981]
Who is BS EN 50050-2 - Safety requirements hand-held spraying equipment for?
BS EN 50050-2 on hand-held spraying equipment is useful for:
- Hand-held spraying equipment manufacturers
- Product designers
- Quality control department
- Safety department
Why should you use BS EN 50050-2 - Safety requirements hand-held spraying equipment?
Hand-held or hand-operated equipment is equipment that is used for electrostatic coating using ignitable coating powders, generally comprises of applicator (with corona charging or triboelectric charging), coating powder supply system, control device, high voltage supply system for corona charging (can be integral to the applicator) and connecting cable. BS EN 50050-2 covers explosion hazard, electric hazards and hazardous malfunctions (e.g. shortcut of electronic safety circuits) that occur due to interferences of the high voltage equipment and the components of the control and safety systems.
BS EN 50050-2 provides general requirements that shall be used while manufacturing the hand-held spraying equipment. This will ensure that your product adheres to safety standards. BS EN 50050-2 provides test methods that helps to determine the efficiency of the product.
