1.1 This European Standard specifies the requirements for stationary electrostatic application
equipment for ignitable coating powders to be used in explosive atmospheres generated by their own
spray cloud. A distinction is made between spraying systems corresponding to EN 50050:2001 and
spraying systems designed for higher discharge energies and/or currents. The charging of ignitable
coating powder can be achieved by applying high voltage or triboelectrically.
This European Standard also specifies the design-related requirements for a safe operation of the
stationary equipment including its electrical installation.
1.2 This European Standard considers three types of electrostatic spraying systems; see 5.1 for
more details.
1.3 This European Standard deals with all hazards significant for the electrostatic spraying of
coating materials, 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, and the protection of persons from
electric shocks.
1.4 This stationary equipment is classified as equipment of group II, category 2D or category 3D
for use in potentially explosive areas of zone 21 or 22, respectively.
