EN 1953-2013 pdf download.Atomising and spraying equipment for coating materials – Safety requirements.
Hand-held electrostatic applicators shall satisfy the requirements of EN 50050 or EN 50059.
Automatic electrostatic applicators shall satisfy the requirements of EN 50176. EN 50177. EN 50223 or EN 50348.
Electrical elements (e.g. digital displays, heating systems, initiators) shall satisfy the requirements of
EN 60204-1.
5.4 Safety requirements against thermal effects
Protection against bums on hot surfaces shall be ensured by appropriate insulation of touchable parts of
applicators which can be reached during normal operation.
Hand-held applicators shall be designed to prevent the surface temperature of handle and trigger exceeding
43 °C as indicated in EN ISO 13732-1. Technical means to fuifli this requirement are for example
— sufficient distance between material supply and handle,
— use of insulating materials.
For areas which shall be touched for adjustment or maintenance, a contact time of 4 s shall be used to determine the relevant maximum surface temperatures for the different materials according to
EN ISO 13732-1.
If a contact with surfaces heated to temperatures which are higher than those indicated in EN ISO 13732-1 cannot be prevented, reference to the use of protective dothing shall be given. The requirements for the protective clothing shall be indicated in the information for use (see Clause 7).
5.5 Safety requirements against noise
Applicators shall be designed and constructed to minimise hazards due to noise emissions, considering the technical progress and available means for noise reduction, especially at the sour.
Noise emission values shall be given in the information for use in compliance with EN 14462; see Clause 7.
NOTE 1 Noise reduction measures are relevant for the following equipment, especially: Pneumatic applicator, hydraulic atomising equipment combined with air and rotary atomisers.
NOTE 2 EN ISO 11688-1 includes general technical information, generally accepted technical rules and means for design and construction of low-noise machinery.
NOTE 3 EN ISO 11688-2 contains information related to generation of noise in machinery, plants and systems.
5.6.1 General
Applicators intended for use in potentially explosive atmosphere shall be assessed according to EN 13463-1. The applicators shall comply with the requirements of EN 13463-1 and EN 13463-5.
The ignition hazard assessment according to EN 13463-1 may also lead to the result that no potential ignition source is present. Applicators without potential ignition source need not comply with the requirements dealing with explosion protection.
NOTE 1 Plastic feed cups with volumes less than 1,5 I are not electrostatically charged to a hazardous level dunng operation as foreseen by the manufacturer.
Category 3 applicators shall be designed and manufactured to prevent foreseeable ignition sources which can occur during normal operation.
Category 2 applicators shall be designed and manufactured to prevent ignition sources during frequently occurring failures of equipment or during faulty operating conditions which can generally be expected.
NOTE 2 Complete definitions of Category 2 and Category 3 equipment are indicated in EN 13463—1.
5.6.2 Thermal ignition sources
Applicators shall be constructed to prevent ignitions of explosive atmospheres by hot surfaces
(see EN 13463-1).
Heating systems of applicators shall:
— be designed to safely prevent a heating of the applicators above the maximum surface temperature: or
— be equipped with temperature limiting devices which safely prevent a heating of the applicators above the
maximum surface temperature.
5.6.3 Electrostatic ignition sources
Applicators shall be equipped with a connection to dissipate static electricity via grounding terminal. The connection between applicators and ground terminal shall have a resistance of ≤ 1 MO.
NOTE The connection can be made via the pneumatic or hydraulic hose connection.
Hand-held electrostatic applicators shall comply with the requirements for ignition protection of EN 50050,
Automatic electrostatic applicators shall comply with the requirements for ignition protection of EN 50176, EN 50177 or EN 50223.
5.6.4 Electrical Ignition sources
Electrical parts and components (digital displays, heating devices, initiators etc.) shall comply with the
requirements of EN 60079-0.
5.6.5 Material ignition sources
Construction materials shall be selected to not cause potential reactions or explosion hazards in specific cases (e.g. the combination of aluminium with coating materials or cleaning liquids containing halogenated hydrocarbons under pressure).
Further requirements for materials are given in EN 13463-1.
5.7 Safety requirements against hazards due to dangerous substances
5.7.1 Measures against contact with or absorption of coating materials or cleaning liquids
Applicators shall be designed and constructed to minimise hazards due to contact with or absorption of coating materials or cleaning liquids by the following measures:
— design of seals to prevent leakages,
— construction of joints to pressunsed liquid supply hoses according to 5.2.4.
For hand-held applicators, contamination of operators due to the spray jet and aerosols in the breathing zone shall be reduced to a minimum.
NOTE Suitable measures are. tar instance:EN 1953-2013 pdf download.
