BS EN 1953:2013 pdf download.Atomising and spraying equipment for coating materials -Safety requirements.
Filter which can be released manually shall not be detachable under Avrtung pressure
Pneumatic connectors shall comply with EN ISO 4414.
References for safe releasing of hoses and filters shaM be given in compliance with Clause 7.
5.3 Safety requirements against electrical hazards
Applicators shall be equipped with a connection to dissipate static electncity via grounding terninal. The connection between applicators and grotrd terminal shall have a resistance of S 1MO.
NOTE The connection can be made via the pneumatic or hydrailic hose connecbow
Hand-held electrostatic applicators shall satisfy the requirements & 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-i
5.4 Safety requirements against thermal effects
Protection against bums on hot surfaces shall be ensured by appropriate Insulation of touchable parts of
applicators wtiich can be reached during normal operation.
Hand-held applicators shall be designed to prevent the surface temperature of handle and trigger exceeding
43 t as indicated in EN ISO 13732-1. Technical means to fulfil this requirement are for example
— sufficient distance between material supply and handle,
— use of insulating materials,
For areas wtiich shall be touched for adjustment or maintenance, a contact time of 4s shall be used to determine the relevant maximum surface temperatures for the different matenals according to
EN ISO 13732-1.
If a contact with surfaces heated to temperatures which are higher than those indicated in EN ISO 1 3732-1 cannot be prevented, reference to the use of protective clothing shall be given. The reqtarements 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 prowess and avaltable means for noise reduction, especially at the source.
Noise emission vthies 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 eqwpment, espeaay: Pneumatic applicator. hydraulic alomising equipment contined wtth air and rotary atonilsers.
NOTE 2 EN ISO1 1688.1 includes general technical inlormation, generally accepted techrwcal rules and means for desçn and construction of low-noise machinery.
NOTE 3 EN ISO 11688-2 contains inlormatson related to generation of noise in machinery. plaits and systems.
5.6 Safety requirements against explosion hazards
5.6.1 General
Applicators intended for use in potentially explosive atmosphere shall be assessed acco.ding 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 soixce need not comply with the requirements dealing with explosion protection.
NOTE I Plastic feed cups edh volumes less than 1.51 are not electrostatically charged to a hazardous level dedng 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 dLaing frequently occurnng failures of equipment or dunng faulty operating conditions which can generally be expected.
NOTE 2 Complete lefiriillons c( Category 2 and Category 3 eqment are indicated Wi EN 13463.-I.
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 wtich safely prevent a heating of the applicators above the
maximum surface temperature.
5.6.3 Electrostatic Ignition sources
Applicators shal be equipped with a connection to cssipate static electricity via grounding terminal. The connection between appbcators and ground terminal shall have a resistance of s 1 MO.
NOTE The connection can be made via the pneumatic or hydraulic hose connection.
Hand-held electrostatic apphcators shad 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.
