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 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. 1.3 This European Standard does not apply to:  !machinery for" processing of foodstuffs and pharmaceuticals; SIST EN 12621:2006+A1:2010

EN 61000-6-1:2001 or EN 61000-6-2:1994. NOTE It is recommended that manufacturers use only components that have been identified as conforming for immunity and emission to harmonised EMC standards and apply them in accordance with the supplier’s recommendations. 5.4 Safety requirements and measures against thermal hazards Machines with equipment for heating and/or cooling of coating material shall be designed and constructed to minimise any risk of injury caused by contact, radiation or convection from hot or very cold surfaces of the machine and its parts or coating material. Limits of temperatures of touchable surfaces given in EN 563 shall be observed. The hazard of touching hot surfaces shall preferably be reduced by:  limitation of coating material temperature;  insulation;  guarding to keep distance (screen, barrier, according to EN 953). and where necessary:  marking and warning signals according to EN 894-1, EN 894-2, EN 894-3, EN 61310-1 and EN 981;  instructions of use of personal protective equipment (see 7.2). Protection against burns by hot surfaces shall be secured by means of appropriate insulation or protection against contact of all elements within arm's reach and within the working area. According to EN 563 at an ambient temperature of 20 °C the surface temperature shall be less than 60 °C. Exceptions are permissible in small localised areas of the surface (for example flanges of burners, bolts). Any parts of the machine not normally in contact with the human body which may exceed these temperatures will require special warnings in the instruction handbook including recommended contact time limits as shown in EN 563. Such surfaces shall also be fitted with warning labels indicating the risks and stating the maximum temperature that these surfaces may reach. For pipelines, 1 label/3m is required. For non-metallic components such as hoses and seals, the manufacturer's recommendations shall be observed. Machines with equipment for heating and/or cooling of coating material shall be safeguarded to prevent the coating material exceeding the maximum allowable temperature for the intended use. When temperature limiting controls are used, over-temperature shall be at least be avoided by end of scale of the temperature setting device or protection of the maximum set point by key lock or code system.
