BS EN 12621:2006+A1:2010EN 12621:2006+A1:2010 (E) 5 Introduction This European Standard is a type C standard as stated in EN ISO 12100. Th
25、is European Standard is part of a series of documents prepared by CEN/TC 271/WG2 specifying the health, safety and environmental protection requirements for devices, units and equipment for surface coating: EN 1953 “Atomising and spraying equipment for coating materials“; !EN 12621:2006+A1“ “Machine
26、ry for the supply and circulation of coating materials under pressure“; !EN 12757-1“ “Mixing machinery for coating materials“. The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this European Standard. When provisions of
27、 this type C standard are different from those stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard. BS EN 12621:2006+A1:2
28、010EN 12621:2006+A1:2010 (E) 6 1 Scope 1.1 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 a
29、irless. 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
30、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 t
31、he 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, co
32、uplings, 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 haz
33、ards 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
34、-7:2002 and the supply hoses for this equipment. 1.3 This European Standard does not apply to: !machinery for“ processing of foodstuffs and pharmaceuticals; BS EN 12621:2006+A1:2010EN 12621:2006+A1:2010 (E) 7 design and construction of pipes and hoses; design and construction of coating presses (see
35、 3.23); machinery for the supply of powder coating material. 1.4 This European Standard is not applicable to machinery for the supply and circulation of coating materials under pressure which are manufactured before the date of publication of this document by CEN. 2 Normative references The followin
