1.1This European Standard is applicable to spray booths for spray application of organic coating powder, called in this European Standard "powder spray booths", i.e. machinery and related equipment for automated and/or manual powder coating application processes.This European Standard covers powder spray booths consisting of the following equipment:-forced ventilation system;-air filtering and coating powder recovery system;-coating powder recycling system;-delivery and circulating systems for coating powder (for instance hopper or tank, preparation and transfer new powder feeding);-air conditioning system;-automatic cleaning system;-monitoring and/or control systems;-fire detection and interlocking system;-explosion protection system;-mechanical aspects of product handling systems and reciprocators inside the powder spray booth;-electrical equipment;-powered doors and gatesjoined together within or at a partially or totally enclosed structure (limited by walls, called space) for the controlled processing of spray application of organic coating powder.This European Standard deals with the significant hazards, hazardous situations and events relevant to powder spray booths when they are used as intended and under the conditions foreseen by the manufacturer (see Clause 4).NOTEPowder spray booths are classified in Annex !C".In addition, it defines:-the content of marking;-the minimum requirements for use.1.2This European Standard does not cover:a)powder spray booths in which the coating is applied by immersion in a fluidised bed;b)powder spray booths for application of non combustible and inorganic coating powder and flock;c)spraying equipment as covered by EN 1953, EN 50050, EN 50177;d)machinery for the supply or circulation of coating material under pressure as covered by prEN 12621;e)all loading and unloading systems;f)automatic systems, e.g. robots as covered by EN 775 and control systems of
