1.1 This European Standard specifies the requirements for stationary electrostatic applicationequipment for ignitable liquid coating materials and for hard to ignite liquid coating materials to be used in explosive atmospheres generated by their own spray cloud. A distinction is made between spraying systems corresponding to EN 50050 and spraying systems designed for higher discharge energies and/or currents.This European Standard also specifies the design-related requirements for a safe operation of thestationary equipment including its electrical installation.1.2 This European Standard considers four types of electrostatic spraying systems; see 5.1 for mo
