This European Standard applies to the design and construction of machinery for the supply and circulation of coating and/or auxiliary materials under pressure in the following called ""machine"" (see 3.1). The coating material is supplied by air pressure or airless. NOTE – Machines covered by this European Standard may be linked with e.g. colour mixing machinery, atomising and spraying equipment, spray booths and stands and/or automated coating machinery. The pressure related parts of the machines covered are classified as no higher than category I under article 9 of the Pressure Equipment Directive 97/23/EC. This European Standard deals with the significant hazards, hazardous situations and events relevant to the machinery for the supply and circulation of coating and/or auxiliary materials under pressure, when they are used as intended and under the conditions foreseen by the manufacturer (see Clause 4). Machinery for the supply and circulation of coating and/or auxiliary materials under pressure consists of the following equipment: - pump units; - pressure vessels; - non-pressurised containers; - interconnecting pipes and hoses - flanges, nozzles, couplings, supports, lifting equipment etc.; - agitators; - filters; - pulsation damping devices; - all safety devices (e.g. level monitoring equipment); - equipment for heating and/or cooling of the coating materials. The machine may be fixed or mobile. 1.2 This European Standard excludes: - pressure related hazards of equipment classified as higher than category 1 under article 9 of the Pressure Equipment Directive 97/23/EC; - atomising and spraying equipment as dealt with in EN 1953:1998 and the supply hoses for this equipment; - atomising and spraying equipment as dealt with in EN 50144-2-7:2001, EN 50260-2-7:2002 and the supply hoses for this equipment. This European Standard does not apply to: - machinery for processing of foodstuffs and pharmaceuticals;
