What is BS EN 50223 - ES flock material standard about?
In the process of electrostatic flock application, the flock is transported from a reservoir through an electrical field either by gravitational forces or an airstream or electrostatic forces. As the flock particles disperse due to the flock application device and/or the electric field, they are electrostatically charged by means of high voltage of some tens of kilovolts aligned and, in the form of a cloud, encased by and deposited on the grounded workpiece. They stick to those workpieces, which are covered with an adhesive layer. The adhesive is set at room temperature or by heating. Flock particles not deposited on the workpiece (overspray) are upcast or removed by the exhaust ventilation system, by brushes, or other devices into the flock recovery system.
BS EN 50223 specifies requirements for stationary electrostatic flock application equipment which is designed for applying ignitable flock which may form explosive atmospheres in the flock application area. For stationary electrostatic application devices for an ignitable flock of type B-F, EN 50050-3 is applicable in addition to this standard.
Who is BS EN 50223 - ES flock material standard for?
BS EN 50223 on ES flock material standard is useful for:
- Manufacturers of textile and packaging
- Owners and operators in the garment industry
- Manufacturers of plastic commodities
- Health and safety authorities
- Product development / innovation / research teams
- Quality control teams
Why should you use BS EN 50223 - ES flock material standard?
The flocking process involves applying short monofilament fibres, usually, nylon, rayon, or polyester, directly onto a substrate that has been previously coated with an adhesive. BS EN 50223 specifies the constructional requirements for a safe operation of the stationary equipment of flock application booths, including the electrical installations and the accessories. BS EN 50223 deals with all significant hazards, hazardous situations, and events relevant to flock application booths, when they are used as intended and under conditions which are foreseeable as malfunction by the manufacturer. BS EN 50223 provides you with a list of significant hazards, safety requirements, and measures in addition to testing methods.
Using BS EN 50223 guidelines you can determine requisites for stationary electrostatic flock application equipment which is designed for applying ignitable flock which may form explosive atmospheres in the flock application area. BS EN 50223 enables you to provide your operators with hazard-free working conditions and the customer with suitable, reliable, and high-quality products.
