4 Testing
The tests described in Annexes A to K are intended to verify that a caravan holiday home 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 caravan holiday homes based on established knowledge and within the respective technical
possibilities (see also Annex J).
5 Design and construction
5.1 Occupancy
The manufacturer shall designate the occupancy as the number of berths, both standard and additional
berths, provided by the manufacturer and shall include it in the User's Handbook and his brochures.
The occupancy is also necessary to determine the ventilation requirements (see EN 721).
5.2 Ceiling height
The ceiling height, measured internally from finished floor level to underside of finished ceiling, except
in areas above fixed furniture, shall be not less than 1 980 mm.
The finished floor level shall be measured from the upper surface of any continuous fixed floor covering.
This includes any vinyl carpet backing but not carpet pile.
5.3 Glazed areas
The living area, the area for meals and the kitchen shall each be provided with windows, the total glazed
areas of which shall be equivalent to not less than 10 % of their respective floor areas. Sleeping
accommodation shall be provided with glazed area not less than 5 % of the floor areas. An exterior
glazed area can be classed as a window for this purpose.
Glazed areas to the living area, the area for meals and the kitchen shall have an openable area
equivalent to 5 % of each respective floor area.
The floor area of the unit should be calculated from the total internal floor area excluding partition
walls and separate fixed compartments which extend the full internal height of the unit. All floor area
covered by fixed or loose furniture that does not extend the full height of the unit should be counted
into the area. Transparent or translucent roof lights may be classed as glazed area.
5.4 Doors
At least one exterior door which opens outwards shall be provided.
Sliding doors will be deemed to be acceptable provided that the sliding operation of the door is not
obstructed by a fixture and the door, when open, does not obstruct any emergency exit.
5.5 Glazing
Any glass in external windows, panels and doors that are less than 800 mm above finished floor level
shall be safety glazing class 3B3 !or 3C3" or better in accordance with EN 12600.
5.6 Classification of thermal insulation and heating
The thermal insulation and heating levels for specific climatic conditions shall be classified as follows:
a) grade 1: A caravan holiday home, including windows, doors and roof lights in which the average
thermal transmittance (U) of the elements of construction shall not exceed 1,7 W/(m K). There is
no heating requirement for this grade;
b) grade 2: A caravan holiday home, including windows, doors and roof lights in which the average
thermal transmittance (U) of the elements of construction shall not exceed 1,7 W/(m K);
An average temperature difference of at least 20 K between inside and outside temperatures shall
be achieved in the living area, the area for meals and the kitchen, when the outside temperature
is 0 °C;
c) grade 3: A caravan holiday home, including windows, doors and roof lights in which the average
thermal transmittance (U) of the elements of construction shall not exceed 1,2 W/(m K).
An average temperature difference of at least 35 K between inside and outside temperatures shall
be achieved in all rooms, except the sanitation compartment, when the outside temperature
is −15 °C.
Precautions shall be taken to ensure that all water services still operate when the outside
temperature is −15 °C.
For grade 1, the average thermal transmittance (U) shall be calculated in accordance with the relevant
parts of Annex A. For grades 2 and 3, the average thermal transmittance (U value) and heating
requirements shall be calculated in accordance with Annex A.
5.7 Roof space ventilation
Where there is an air gap between the external roof skin and the insulation material, this air gap shall
be ventilated to the external air.
If space allows, one high level ventilator and one low level ventilator shall be provided.
5.8 Underfloor
Underfloor insulation, if provided, shall be protected to reduce the possibility of degradation by birds or
other animals (for example: rodents).
5.9 Fire behaviour of materials
NOTE Pending harmonized European requirements for the assessment of the fire behaviour of materials,
attention is drawn to national requirements which may apply.
5.10 Stability (resistance to overturning)
Caravan holiday homes of all grades shall be provided with suitable holding-down points, each capable
of resisting 10 kN.
Holding down points shall be located at (1 000 ± 200) mm from the ends of the main longitudinal
chassis members at each corner of the caravan holiday home.
The manufacturer shall indicate the position of the holding down points in the User's Handbook.
5.11 Structural classification of caravan holiday homes
The structure of a caravan holiday home shall be graded according to its ability to withstand one of the
following snow loadings:
a) grade A: A caravan holiday home Grade A resting on its normal supports as defined by the
manufacturer shall be capable of resisting a snow load of 750 Pa, exerted uniformly over the roof.
b) grade B: A caravan holiday home Grade B resting on its normal supports as defined by the
manufacturer shall be capable of resisting a snow load of 1 500 Pa, exerted uniformly over the roof.
c) grade C: A caravan holiday home Grade C resting on its normal supports as defined by the
manufacturer shall be capable of resisting a snow load of 2 000 Pa, exerted uniformly over the roof.
d) grade D: A caravan holiday home Grade D resting on its normal supports as defined by the
manufacturer shall be capable of resisting a snow load of 3 000 Pa, exerted uniformly over the roof.
Compliance can be verified either by the submission of the calculations of a qualified structural
engineer, a worst case failure mode effect analysis (FMEA) or by testing in accordance with Annex B.
The structure is considered to have passed the test if it remained safe and returned to an acceptable
condition on removal of the load applied. To satisfy the requirement of “remain safe”, all designated
means of escape egress from the unit (doors and windows) shall function during and after the test.
6 Internal equipment
6.1 Bunks
6.1.1 General
Free standing bunks shall be in accordance with 6.1.2, 6.1.3 and EN 747-1.

Bunks shall be provided with mattresses or be upholstered.
6.1.3 Clearance
The clear width of a bunk shall be not less than 500 mm. The clear height over two-thirds 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 C.
6.1.4 Protection against falling out
6.1.4.1 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. Any gap between one element of protection and another shall conform to 6.1.8. Nevertheless, 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
holiday home is to be first sold with the following wording:
“Not suitable for children under 6 years old without supervision”.
6.1.4.2 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 D.
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.
6.1.4.3 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 a 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.
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 D.
Any gap created during the resistance test shall be measured in accordance with Annex H.
6.1.5 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 holiday home.
The mechanical strength shall be tested in accordance with Annex E.
6.1.6 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 F.
6.1.7 Access to high level bunks
A means of access to an high level bunk shall be provided, such as surfaces of furniture, footholes in a
solid component, handles or a ladder which may be fixed or be able to be attached to the bunk in a safe
manner.
The width of the treads between positive 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 G, 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 holiday home, 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 holiday home according to Annex G.
6.1.8 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 H.1) beyond the point at which the diameter
of the cone is 75 mm, when measured from above in accordance with H.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 H.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.
