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 in order 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.
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 all separate step(s) be attached to the caravan when in use to improve their stability.
It is recommended that the rise of the steps be equal.

The clear width of a bunk shall be not less than 500 mm. 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
Any bunk where the uncompressed upper surface of the mattress or upholstery is placed at a height of more than
1 000 mm from the floor, shall be protected on all sides to prevent the occupant from falling out.
All protections shall be secured against unintentional loosening.
Upper bunks shall be provided with a label 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. The protection shall be continuous except for a section of 300 mm to 500 mm
to allow for means of access.
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 at least 500 mm wide.
Means of emergency exit from the bunk shall be accessible from the upper surface of the bunk.
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 folding bunks
If a bunk is designed to fold away it shall be secured against unintentional folding away.
A folding bunk shall not unintentionally move from its stored position. Both conditions will be tested in accordance
with Annex I.
6.1.6 Access to upper bunks
A means of access to an upper bunk shall be provided, such as surfaces of furniture, footholes 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.
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 mm ± 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 between12 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 removed to the extent necessary to allow the tests to be carried out.
