Atomising and spraying equipment for coating materials - Safety requirements
This European Standard applies to the design and construction of spraying equipment for 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. The coating material may be atomised by air, by airless, by airless with the assistance of air or mechanically by centrifugal force. With atomisation by centrifugal force, the atomised coating material may be assisted towards the workpiece by controlled air veils. The atomising and spraying equipment may also be electrostatically supported. This standard specifically refers to hazards created by or resulting from the use of atomising and spraying equipment, if it is used as determined and in accordance with the foreseeable conditions of the manufacturer (see clause 4). Atomising and spraying 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 specifying and installing the atomising and spraying equipment. Further topics for this standard are minimum user information: - Operation manuals, - Marking. This standard excludes: - Flocking machines; - Equipment related to the atomising and spraying of foodstuffs and pharmaceuticals; - Artists airbrushes; - Machinery for 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.

Razprševalna in brizgalna oprema za prekrivne materiale - Varnostne zahteve
Ta evropski standard se uporablja za načrtovanje in izdelavo brizgalne opreme tako za ročno kot avtomatsko nanašanje prekrivnih materialov v obliki tekočine, pastozne mase (poltrde) in prahu. Ročna oprema je za ročno rabo, avtomatska oprema pa se upravlja s pomožnimi signali ter je montirana bodisi togo ali na avtomatske naprave, kot so roboti ali koračni oz. rotacijski stroji. Prekrivni material se lahko razprši z zračnim brizganjem, z brezzračnim brizganjem, z brezzračnim brizganjem s pomočjo zračnega ali mehansko s centrifugalno silo. Pri razprševanju s centrifugalno silo se lahko razpršen prekrivni material usmeri proti obdelovancu z nadzorovanimi zračnimi zavesami. Razprševalno in brizgalno opremo je mogoče tudi elektrostatično podpreti. Ta standard se nanaša zlasti na nevarnosti, ki jih povzroča ali nastanejo zaradi uporabe razprševalne in brizgalne opreme, če se uporablja kot določeno in v skladu s pogoji, ki jih je predvidel proizvajalec (glej Klavzulo 4).

Necessary protective measures shall be taken in respect of the risks that cannot be eliminated. The user must be warned of these risks. SIST EN 1953:2000+A1:2010
EN 1953:1998+A1:2009 (E) 12 5.2 Mechanical Safety Requirements 5.2.1 For hand-held atomising and spraying equipment, the distances of moveable to fixed parts shall be wide enough to avoid trapping or pinching of any part of the human body. Where this is not possible, as in the case of the trigger and gun body, the design and construction of the equipment should be such that it reduces the hazard to a minimum. All parts of the equipment shall be smooth and free of sharp corners. Additionally see Normative References, in particular EN349, EN614-1 and ENV26385. 5.2.2 For hand-held atomising and spraying equipment, the release of the trigger interrupting the flow of material must not, at any time, be prevented by recoil forces. Forces which have to be applied by hand to trigger the atomising and spraying equipment shall follow the recommendations of EN614-1 The user shall be warned, in the operation manual, that repetitive strain injury may occur from recoil forces. For automatic atomising and spraying equipment, the mounting elements shall be designed and constructed in such a way that they can withstand any recoil forces that may occur. 5.2.3 The user shall be warned of any piercing hazards that may exist with the particular equipment. 5.2.4 Manually operated hand-held atomising and spraying equipment for use with liquid and/or paste (semi-solid) coating materials shall be designed and constructed in such a way that unintended operation is prevented by mechanical safety devices such as, but not limited to, trigger and/or fluid needle locking mechanisms. !When fixed guards are applied, they shall be fixed by systems that can be opened or removed only with tools. Their fixing systems shall remain attached to the guards or to the machinery when the guards are removed. Where possible, these guards shall be designed in such a way that they can only remain in place using their fixing system." The spray jet shall be guarded in such a way that the injection of coating material and/or solvents and/or compressed air into any part of the human body is prevented as far as possible. Hand-held atomising and spraying equipment shall be constructed in such a way that the release of the trigger or actuating valve stops the flow of coating material and/or solvents from the equipment or cuts-off the supply of coating material and/or solvent to the equipment. 5.2.5 Atomising and spraying equipment shall be designed and specified in such a way that it resists a burst pressure of 4 times the maximum working pressure. The equipment must also be capable of functioning to specification after being subjected to a proof pressure of 2 times the maximum working pressure. Any devices preventing unintended pressures such as safety valves, shear pins etc. which are fitted to the equipment shall be replaced prior to the pressure testing with components which are capable of withstanding the specified test pressures to which the equipment is to be subjected. 5.3 Electrical Safety Requirements 5.3.1 The requirements specified in EN50053-1, EN50053-2 and EN60335-1 must be observed for hand-held atomising and spraying equipment.
