SIST EN 1647:2012



EN 1647:2012 (E) 6 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, 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 (see also 10.1.6). 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 permanent fitting and the door, when open, does not obstruct any emergency exit. 5.5 Glazing Glass in external windows, panels and doors that are less than 800 mm above finished floor level shall be safety glazing. NOTE Pending harmonized European requirements for the assessment of the safety glazing, attention is drawn to national requirements which may apply. 5.6 Kitchen location When a separate kitchen compartment is provided, that can be closed off from other parts of the caravan holiday home by fully closing doors, there shall be two doors, separated by a space, ventilated to the exterior, between the kitchen and the toilet compartment. 5.7 Classification of thermal insulation and heating The thermal insulation and heating levels for specific climatic conditions shall be classified as follows: SIST EN 1647:2012



EN 1647:2012 (E) 7 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/(m2 . 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/(m2 . K); An average temperature difference of at least 20 K between inside and outside temperatures shall be achieved in lounge, dining room and 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/(m2 . K). An average temperature difference of at least 35 K between inside and outside temperatures shall be achieved in all rooms, except the toilet 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. 5.8 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. 5.9 Underfloor Underfloor insulation, if provided, shall be protected to reduce the possibility of degradation by birds or other animals (for example: rodents). 5.10 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. 5.11 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. 5.12 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: SIST EN 1647:2012



EN 1647:2012 (E) 8 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 Pa1), 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 Pa1), 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 Pa1), 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 Pa1), exerted uniformly over the roof. Compliance can be verified either by the submission of the calculations of a qualified structural engineer 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 Mattress and/or upholstery Bunks shall be provided with mattresses or be upholstered. 6.1.2 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. 6.1.3 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. Any gap between one element of protection and another shall conform to 6.1.7. Nevertheless, no gap shall exceed 75 mm. 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".
1) Provisional until confirmation by EUROCODE 1. SIST EN 1647:2012



EN 1647:2012 (E) 9 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 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. 6.1.3.3 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 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. 6.1.4 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 holiday home. The mechanical strength shall be tested in accordance with Annex E. 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 F. 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 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. SIST EN 1647:2012



EN 1647:2012 (E) 10 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. 6.1.7 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 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. 6.2 Cooking appliance If space is provided for the installation of a cooker, the space shall be at least 540 mm wide by 600 mm deep. 6.3 Toilets (W.C.)
