BS EN 50348:2010 pdf free.Stationary electrostatic application equipment for non-ignitable liquid coating material—Safety requirements.
BS EN 50348 This European Standard specifies the requirements for stationary electrostatic application equipment for non-ignitable liquid coating materials which do not generate an explosive atmosphere inside the spraying area. A distinction is made between spraying systems corresponding to EN 50050 an  spraying systems designed for higher discharge energies and/or currents.This European Standard also specifies the design-related requirements for a safe operation of the stationary equipment, including its electrical installations.
This European Standard considers two types of electrostatic spraying systems, see 5.1 for more details.
Noise has not been dealt with in this standard as it is not considered to be a significant hazard of stationary electrostatic application equipment for non-ignitable liquid coating material. For any other
health protection, see EN 12215:2004，5.5. For fire prevention and protection (e. g. fire hazards due to other sources), see also EN 12215:2004, 5.7.1.
This European Standard deals with all significant hazards, hazardous situations and events, which are relevant for stationary electrostatic application equipment for non-ignitable liquid coating and cleaning materials which do not generate an explosive atmosphere inside the spraying area, provided they are used as intended by the manufacturer.

voltage-controlled operation:open control circuit system without feedback of the output high voltage. During the voltage-controlled operation the output high voltage is adjusted generally at a defined operational current. The output high voltage, however, is not maintained constant by a control device, it varies depending on the operational current and the on-load behavior of the high voltage device.BS EN 50348 pdf download.
