4 Testing
The tests described in Annexes A to N are intended to verify that a caravan representative of a given model,
including its fixtures and fittings, meets the requirements of this European Standard.
These tests are intended to simulate the most onerous conditions for the relevant characteristics.
It is recommended to take environmental aspects into account during development, production and disposal
of caravans based on established knowledge and within the respective technical possibilities
(see also Annex O).
5 Design and construction
5.1 Occupancy
The manufacturer shall designate the occupancy as the number of berths, both standard berths and
additional berths provided by the manufacturer, and shall include it in the user's handbook and in his
brochures. The occupancy is also needed to determine the ventilation requirements (see EN 721).
5.2 Rigidity
When stationary, with the floor horizontal and all corner steadies extended to the ground, an upward thrust
of 1 500 N applied to one corner steady for a duration of 15 min shall not cause the caravan to distort to an
extent that would make any door or window difficult to open.
Rigidity shall be tested in accordance with Annex A.
5.3 Corner steadies
Each caravan shall be equipped with four steadies, one at each of its four corners. Each steady shall be
retractable and adjustable in height. Each steady shall be capable, when extended, of carrying a load of not
less than 25 % of the maximum technically permissible laden mass of the caravan. An appropriate operating
tool shall be provided.
A certificate, from the corner steady manufacturer or supplier shall accompany the caravan to be tested
showing, either by calculation or by test, the loading capability of each type of corner steady.
5.4 Grab handles
Four external grab handles for manoeuvring the caravan shall be located externally to the body work, one on
each side at the front and one on each side at the rear.
For those caravans with a maximum technically permissible laden mass not exceeding 750 kg, two grab
handles at the front of the caravan one on each side are sufficient.
The hand clearance aperture of each grab handle shall be not less than 30 mm × 120 mm.
The grab handles shall be tested according to Annex B.
There shall be no visible permanent deformation or loosening of the grab handle and/or of its fixings.
5.5 Entrance steps
5.5.1 Heights
When the entrance height of the caravan, measured at maximum technically permissible laden mass, and
standing on horizontal ground, exceeds 400 mm, the caravan shall either be fitted with an entrance step,
attachable or integral with the structure of the caravan, or a separate entrance step(s) shall be provided. An
integral entrance step can be either retractable, folding or fixed.
The rise of the first tread shall not exceed 400 mm. The rise of any other tread shall not exceed 300 mm.
It is recommended that the rise of the steps be equal.
5.5.2 Minimum tread dimensions
The minimum tread dimensions shall be:
a) attachable or integral entrance steps: 150 mm going over a minimum, uninterrupted width of 320 mm;
b) separate steps: 270 mm going over a minimum, uninterrupted width of 450 mm.
5.5.3 Mechanical strength
An entrance step and any fixing devices shall be capable of withstanding a force of 2 000 N applied to any
surface area of 100 mm × 150 mm of the tread.
After application of this force for a period of 5 min, any permanent deformation caused shall not exceed
5 mm.
The strength of each step shall be tested in accordance with Annex C.
5.5.4 Slip resistance test
5.5.4.1 Attachable or integral step
An attachable or integral step shall have a slip resistant surface.
The slip resistance shall be tested in accordance with Annex D.
5.5.4.2 Separate entrance step
A separate step shall have a slip resistant surface. The slip resistant surface shall be tested in accordance
with Annex D after having immobilized the feet or base of the step.
In addition, a separate step shall remain stable when tested in accordance with Annex E.
5.6 Doors
5.6.1 Dimensions
Each exterior door opening for rigid caravans shall have a minimum clear height of 1 590 mm and a
minimum clear width of 480 mm and corners of maximum radius of 90 mm. The locking system may intrude
on the minimum width up to 30 mm and for a maximum height of 150 mm, regardless of the number of
locks.
Each exterior door opening for rigid folding caravans shall have a minimum clear height of 1 300 mm and a
minimum clear width of 480 mm and corners of maximum radius of 90 mm. The locking system may intrude
on the minimum width up to 30 mm and for a maximum height of 150 mm, regardless of the number of
locks.
5.6.2 Securing doors
Each exterior door shall be fitted with a locking device capable of keeping it closed when subjected to all
forces caused by the movement of the vehicle in normal traffic conditions.
Interior doors shall be capable of being kept in a fixed position, open or closed, in the above conditions.
5.7 Awning Rail
Any awning rail shall permit the correct fitting of an awning complying with EN ISO 8936.
6 Internal equipment
6.1 Bunks
6.1.1 Mattress and/or upholstery
Bunks shall be provided with mattresses or be upholstered.
6.1.2 Clearance
The clear height over 2/3 of the surface area of the bunk shall be not less than 500 mm when measured from
the compressed surface of the mattress or upholstery in accordance with the test in Annex F.
6.1.3 Protection against falling out
6.1.3.1 General
High level bunks shall be protected on all sides to prevent the occupant from falling out. Any gap between
one element of protection and another shall conform to 6.1.7. No gap shall exceed 75 mm.
All protections shall be secured against unintentional loosening.
High level bunks shall be provided with a label written in the language of the country where the caravan is to
be first sold with the following wording:
“Not suitable for children under 6 years old without supervision”.
6.1.3.2 Rigid protection
For rigid protection, the minimum height of the protection shall be at least 150 mm above the uncompressed
upper surface of the mattress or upholstery. To allow entry, an access gap of 350 mm to 550 mm measured
at its narrowest point shall be provided.
Where a rigid protection presents an apparent flexibility, its resistance shall be tested in accordance with
Annex G.
A protection is considered as rigid if it is not bent more than 10 mm under a force of 100 N applied
horizontally in the middle of the protection.
6.1.3.3 Protection by curtains or nets
Alternatively, the protection may be obtained by means of curtains or nets. The minimum height of the
protection shall be at least 160 mm above the uncompressed upper surface of the mattress or upholstery,
when the upper edge is loaded with 100 N in vertical direction downward.
To allow access to the bunk, the curtains or nets on at least one side of the bunk may be detachable, allowing
an opening 350 mm to 550 mm.
The curtains or nets shall be capable of resisting a force of 100 N applied horizontally towards the outside of
the bunk for 15 s to any point and this shall not result in any tearing nor detaching nor creating any gap
larger than 60 mm at the lower edge of the protection.
The strength of the curtains or nets shall be tested in accordance with Annex G.
Any gap created during the resistance test shall be measured in accordance with Annex K.
6.1.4 Mechanical strength
A force of 1 000 N applied vertically downwards, for 1 h, from the midpoint of each side member of any bunk
where the upper surface of the compressed mattress or upholstery is placed at a height of more than
500 mm from the floor, shall neither cause permanent deformation of more than 5 mm of the frame of the
bunk nor damage the fixing of the bunk to the structure of the caravan.
The mechanical strength shall be tested in accordance with Annex H.
6.1.5 Security of bunks
If a bunk is designed to fold away, it shall be secured against unintentional folding away.
If a bunk is designed to be stored during transportation, it shall be secured against unintentional movement
when stored.
All bunks shall not unintentionally move. All bunks shall be tested in accordance with Annex I.
6.1.6 Access to high level bunks
A means of access to an high level bunk shall be provided, such as surfaces of furniture, foot holes in a solid
component, handles or a ladder which shall be fixed or be able to be attached, to the bunk, in a safe manner.
The width of the treads between supports shall be at least 250 mm.
The distance between the top foothold and the uppermost part of the bed structure, e.g. the side rail or
safety barrier, at the point of access, shall not be more than 400 mm.
When a ladder is used, the upper surfaces of the treads shall be equally spaced within a tolerance
of ± 12 mm, and the unobstructed distance between consecutive treads shall be (225 ± 25) mm.
When tested in accordance with Annex J, the ladder shall not move when subjected to a downward static
load of 1 000 N and a horizontal static load of 500 N; nor shall the ladder or its treads break or deflect
permanently by more than 5 mm.
Where it is impractical to test the bunk ladder in the caravan, it is acceptable to test an identical
configuration of the ladder, its method of fixing and its range of positions of use, outside the caravan
according to Annex J.
6.1.7 Protection against entrapment
When ready for use, a bunk and its means of access shall not contain any open-ended tubing; nor shall there
be projections, holes, loose washers, speed fixing nuts or crevices on which clothing or any part of the body
could become snagged or trapped. Tension springs in the base structure are excluded. All edges, corners and
projecting parts that are accessible shall be free from burrs and sharp edges.
If the base of a bunk is not covered by permanently fixed upholstery, any gap in the base not covered by the
mattress shall not permit the passage of the cone (see K.1) beyond the point at which the diameter of the
cone is 75 mm, when measured in accordance with K.2.
Any other gap or space within the structure of the bunk which is accessible from the upper surface of the
bunk, including mattress where applicable, shall be between 12 mm and 25 mm or between 60 mm and
75 mm, (tested in accordance with K.3) or equal to or larger than 200 mm.
When a gap cannot be tested because a constructional feature prevents proper positioning of the cone, the
constructional feature may be
