European foreword
This document (prEN 17281:2018) has been prepared by Technical Committee CEN/TC 197 “Pumps”,
the secretariat of which is held by AFNOR.This document is currently submitted to the CEN Enquiry.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this
document.This standard contains requirements and verifications, on the basis of which vehicle washing systems
can be granted the CE mark.---------------------- Page: 6 ----------------------

Introduction
The scope of this standard describes the hazards dealt with. For hazards, which are not dealt with in this
standard, it is essential that the machines comply with EN ISO 12100, if appropriate.
Where an example is given for the clarification of the text, it should not be considered as the only
authorized solution. Each other solution is admitted provided the same result is achieved and an equal
level of safety for equal function is guaranteed.It is not the purpose of this standard to exclude new designs of vehicle washing systems from a later
integration. It is essential that a new design at least complies with the safety requirements of this
standard.If vehicle washing systems are operated under special conditions e.g. under the influence of the weather,
it is essential that the constructive measures, components and materials as well as service lines are
adapted to these conditions.This standard does not contain requirements for the service life of vehicle washing systems, as it depends
on the site and on special demands of the clients.When preparing the standard, carelessness of the user has partly been taken into account. The basis,
however, is intended, not unintended use.---------------------- Page: 7 ----------------------

5 Safety requirements and safety measures
5.1 General safety requirements
5.1.1 Shearing and crushing points at power-operated movable parts
Crushing and shearing points at power operated parts shall be avoided in the work and traffic zones up
to a height of 2 m above the respective floor space for persons or, if this is not possible, they shall be
protected. The hazard points may be avoided or protected by e.g.:– Safety distances according to EN 349 and EN ISO 13857;
– Guards;
– Safety devices;
– Deterring devices.
NOTE 1 Counterweights could be a point of crushing and shearing.
NOTE 2 The space between two independent moving tandem roll over vehicle washing systems could be a point
of crushing.5.1.2 Tripping and twisting points
Tripping and twisting points in the work or traffic zones shall be avoided or protected.
Tripping points caused by ground rails are avoided if the rails are laid evenly with the ground.
Nevertheless, all necessary steps shall be taken to ensure that tripping and twisting points are avoided.
Twisting points are considered to be protected if they are made visible by appropriate surrounding
conditions, e.g. by sufficient lighting and/or coloured design.Equipment such as e.g. wheel entering devices and on-floor under-chassis washing systems, which cannot
be realised below a certain level for functional reasons shall be visible by appropriate surrounding
conditions, e.g. by sufficient lighting and/or coloured design.5.1.3 Gears and sprocket wheels
Enclosures for gears and sprocket wheels in the work and traffic zones shall not have openings not in
compliance with EN ISO 13857. If they are positioned outside the work and traffic zones, at least the nip
points shall be protected against contact.5.1.4 Belt and rope drives
The nip points at belt and rope drives within the work and traffic zones shall be protected by guards or
deterring devices.5.1.5 Supporting means
The supporting means for horizontal system components shall be designed with a safety factor for
breaking load divided by load bearing capacity of at least 6 to ensure the safety of the machine.
NOTE The factor is in conformity with EN 14492-2.In the event of breaking of a supporting means, roof brushes or roof nozzles shall not fall down
uncontrolled. The drop distance shall only be 0,3 m at maximum within the work and traffic zone.

prEN 17281:2018 (E)
5.1.6 Horizontal and vertical system components
Horizontal and vertical system components such as roof brushes with horizontal axis or horizontal roof
nozzle carriers shall automatically stop at their final positions. Furthermore, an additional protection
device shall stop the system components at the end of the guide rails.NOTE This can for example be achieved by means of operational limit switches in connection with a fixed
stopper or an emergency limit switch or a fixed stopper in connection with an overload protection.
5.1.7 Guides/guide pulleysNip points between guides and guide pulleys of roof brushes, roof nozzles, side brushes and wheel wash
brushes within the work and traffic zones shall be so protected that it is not possible to introduce a hand
into them.5.1.8 Guiding system
Vehicle washing systems shall be equipped with guiding devices for vehicles, leading the driver and
his/her vehicle into a correct centre position.NOTE This is only mandatory for self-service washers.
5.1.9 Positioning system
Vehicle washing systems shall be equipped with one positioning device (each), leading the user of the
system with his/her vehicle into a correct longitudinal start position for the washing or drying process.
NOTE 1 To show the customer that he is in the correct position, a signal can be sufficient.
NOTE 2 This is only mandatory for self-service washers.5.1.10 Wall and ceiling rails
Vehicle washing systems or parts of systems which are supported or guided by wall or ceiling rails shall
be so constructed that they cannot derail or crash.5.1.11 Ground rails
Fixing elements for ground rails in the work and traffic zones, e.g. screws, shall be sunk in the rail base or
so designed that no crushing points with the front surface of the travelling mechanism result.
NOTE The fixing elements at systems for rail vehicles may be designed in the same way as those for railways.
5.1.12 Protruding componentsProtruding components as e.g. retainer keys, screws and lubricating devices at rotating parts shall be
enclosed when there is the risk of entanglement of body parts or clothing, even if they are outside the
work and traffic zones.5.1.13 Accessible covers
The width of openings in accessible covers on the work and traffic zone floor shall be 4 cm at maximum.
NOTE 1 Accessible covers are e.g. grids, sheets and working platforms.NOTE 2 Wider openings were experienced to lead to accidents caused by twisting. Openings in accessible covers
can e.g. be necessary for under-chassis washing systems.Accessible covers provided by the manufacturer shall be of a non-slip type with a slope angle between
19° – 27°.---------------------- Page: 14 ----------------------
oSIST prEN 17281:2018
prEN 17281:2018 (E)
5.1.14 Treads
Surfaces which are intended to be treads shall be safe when accessed. They shall be protected against
unintended displacement.Surfaces of treads shall be of a non-slip type with a slop angle between 19° – 27° and a minimum volume
3 2of 4 cm /dm displacement space below the walking area, in connection with EN ISO 14122-2.
5.1.15 Vehicle wheel guidesThe sides of the rail guides shall be constructed in a way that risks are avoided.
5.1.16 Vehicle displacement devicesCrushing points between vehicle displacement devices and chassis frame, ground rims, or under chassis
washing systems shall be avoided. If crushing points cannot be avoided, they shall be protected. If an
inclination is used as a measure to avoid a crushing point, then an angle of maximum 30° (see Figure A.2,
angles α, β) shall be realised.5.1.17 Liquid jets at vehicle washing systems
Hose pipes of liquid jets used in vehicle washing systems shall be so guided that they cannot be damaged,
squeezed or driven over. Excessive tension or bending loads shall be avoided.– Hose fittings shall be suitable for environmental conditions e.g. chemistry, climate, pressure.
– High pressure pipework should be designed with a maximum operating pressure from at least 1,5
times the nominal pressure referring to EN 60335-2-79.– Unintended exceeding of pressure and temperature shall be prevented.
– Hot surfaces of liquid heaters should be designed in accordance with EN ISO 13732-1.
– Hazards caused by combustion gases shall be avoided at oil- or gas- fired liquid heaters of liquid jets.
– When using flammable liquids, an explosive atmosphere shall be avoided.– It shall be ensured that no persons are endangered by a liquid jet when vehicle washing systems are
used as intended....
