This European Standard forms part of a series of standards specifying the health, safety a
27、nd environmental protection requirements for devices, units and equipment for surface coating: Atomizing and spraying equipment for coating materials; Machinery for the supply and circulation of coating materials under pressure; Mixing machinery for coating materials. The equipment concerned and the
28、 extent to which hazards are covered is indicated in the scope of this standard. The equipment shall comply, as appropriate, with EN 292-1 and EN 292-2 for hazards which are not covered by this standard. 1 Scope This European Standard applies to the design and construction of spraying equipment for
29、both manual and automatic application of liquid, paste (semi-solid) and powder coating materials. The manual equipment is hand-held and the automatic equipment is operated by auxiliary signals and mounted either rigidly or onto automated devices such as robots or reciprocating or rotary machines. Th
30、e coating material may be atomized by air, hydromechanically (airless) with or without air assistance, or mechanically by centrifugal force. With atomization by centrifugal force, the atomized coating material may be assisted towards the workpiece by controlled air veils. The atomizing and spraying
31、equipment may also be electrostatically supported. This standard specifically refers to hazards created by or resulting from the use of atomizing and spraying equipment, if it is used as determined and in accordance with the foreseeable conditions of the manufacturer (see clause 4). Atomizing and sp
32、raying equipment may be linked with supply systems, control circuits, spray booths and/or automated machinery, none of which are covered by the scope of this standard. This may result in the overlapping of some hazards or risks. Such hazards or risks should be taken into consideration when specifyin
33、g and installing atomizing and spraying equipment. Further topics for this standard are minimum user information: operation manuals; marking. This standard excludes: flocking machines; equipment related to the atomizing and spraying of foodstuffs and pharmaceuticals; artists airbrushes; machinery fo
34、r the supply and/or circulation of coating materials under pressure; automated devices such as robots, reciprocating or rotary machines. This standard applies to equipment constructed after the date of issue of this standard. 2 Normative references This European Standard incorporates, by dated or un
35、dated reference, provisions from other publications. These normative references are cited at appropriate places in the text and the publications are listed hereinafter.

For the purposes of this standard, the following definitions also apply. 3.1 General The coating materials for use with the atomizing and spray
45、ing equipment can either be delivered to the equipment by a pump or a pressure vessel via a supply hose or by an integrated gravity or suction cup. For atomizing and spraying equipment fitted with a gravity or suction cup only compressed air is supplied to the equipment and the coating material eith
46、er flows from the gravity cup or is sucked from the suction cup. Atomizing and spraying equipment which has the coating material supplied via a hose from a pump or pressure vessel may also be supplied with compressed air. The coating material is emitted from the atomizing and spraying equipment via
47、a valve which is controlled either manually by the trigger or automatically by auxiliary energy from an actuator system. 3.2 atomizing and spraying equipment any type of device which can be used to atomize coating materials. Atomization may be achieved by air, hydromechanically (airless) with or wit
48、hout air assistance, or by centrifugal forces such as rotating bells or discs NOTEAtomizing and spraying equipment (either manual or automatically operated) normally consists of a gun body, a coating material valve either located inside the body or integrated with it and a trigger mechanism which op
49、erates the valve. 3.3 safety devices devices for atomizing and spraying equipment which aim to prevent the unintended spraying of a coating material. Safety devices of this type are such as, but not limited to: trigger guards; trigger locking devices; fluid needle locking mechanisms. 3.4 electrostatic atomizing and spraying equipment equipment used for the atomizing and spraying of coating materials with the assistance of an electrostatic charge Such equipment can be fitted
