11、repared under the direction of the Basic Data and Performance Criteria for Civil Engineering and Building Structures Standards Policy Committee and is identical with ISO 8817:1990 “Leisure accommodation vehicles Leisure homes Habitation and stability requirements” published by the International Orga
12、nization for Standardization (ISO). It is one of a series that is being published for leisure accommodation vehicles and transportable accommodation units. It supersedes BS 4989:1984, which is withdrawn. The Technical Committee has reviewed the provisions of IEC 364-7-708:1988 (which are to be incor
13、porated in the sixteenth edition of the Regulations for Electrical Installations1) published by the Institution of Electrical Engineers), to which reference is made in the text, and has decided that they are acceptable for use in conjunction with this standard. The Technical Committee has also revie
14、wed the provisions of ISO/DIS 7421.3 and has decided that they are acceptable for use in conjunction with this standard. It is anticipated that, when published, it will be implemented as BS 6762-4. The manufacture and use of all asbestos based products is covered by the requirements of the Control o
15、f Asbestos at Work Regulations 1987, introduced on 1 March 1988. These set out comprehensive provisions covering work activities involving exposure to asbestos. Advice on how to comply with these regulations can be obtained from the manufacturers of the material, from the Asbestos Information Centre
16、, St Andrews House, 22-28 High Street, Epsom, Surrey KT19 8AH, from the local area office of the Health and Safety Executive or from the Environmental Health Department of the Local Authority. WARNING. Breathing asbestos dust is dangerous to health and precautions have to be taken during the manufac
17、ture and use of these products. Particular note has to be taken of the Asbestos Products (Safety) Regulations 1985 and the Asbestos Products (Safety) (amendment) Regulations 1987, made under the consumer Safety Act 1978 also of the Asbestos (Prohibitions), Regulations 19852) and the Asbestos (Prohib
18、itions) (amendment) Regulations 1988 made under the Health and Safety at Work etc. Act 1974, which prohibit the supply of products containing amosite or crocidolite (“brown” asbestos and “blue” asbestos respectively) and set out requirements for the labelling of all products containing asbestos.

25、es of leisure homes “standard”, “high altitude” and “extra-high altitude” used for temporary or periodic habitation, and that retain their mobility to enable them to be resited or transported at any time. It also specifies degrees of resistance to snow loads and wind loads of the structure of a leis
26、ure home and the minimum information to be included in a Users Handbook provided with a leisure home. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard.

30、4 Grades of leisure homes 4.1 Grading There shall be three grades of leisure home: a) standard, for siting at altitudes of 700 m and below; b) high altitude, for siting at altitudes above 700 m and up to and including 1 200 m; c) extra-high altitude, for siting at altitudes above 1 200 m. 4.2 Requir
31、ements All grades of leisure homes shall comply with the requirements of clauses 5 and 7 to 12. In addition the standard grade shall comply with the requirements of 6.1.1, the high altitude grade with the requirements of 6.1.2 and the extra-high altitude grade with the requirements of 6.1.3. 5 Desig
32、n 5.1 Accommodation The accommodation shall provide a living space, a space for meals, a kitchen, a sleeping area or areas and space for toilet and washing facilities. NOTEThe living and meal areas may also provide the sleeping facilities. 5.2 Occupancy Occupancy shall be described by stating the nu
33、mber of double and/or single berths, e.g. one fold-away double bed, one fixed single bed, two convertible seat/bunks, two childrens bunks. 5.3 Ceiling height Ceiling height, measured internally, shall be not less than 1 980 mm. 5.4 Windows The living space, the space for meals, the kitchen and the s
34、leeping accommodation shall be provided with windows, the total glazed areas of which shall be not less than 10 % of their respective floor areas. Windows to the living space, the space for meals and the kitchen shall be openable to the extent of 5 % of those respective floor areas (see also 10.1.3)
35、. 5.5 Doors An external door shall be provided which shall open outwards. 5.6 Glazing Glass in windows and doors that is less than 800 mm above floor level shall be safety glass. 5.7 Heating requirements 5.7.1 Calculation The method of calculation set out in Annex B shall be used to calculate the he
36、ating needs for specific climatic conditions. 5.7.2 Winter use For a leisure home intended for continuous or prolonged use in winter conditions, an average temperature difference of 35 K calculated as set out in Annex B shall be achieved and any heating installation fitted or recommended shall achie

38、 and be so constructed that the average coefficient of thermal transmittance, U, of a leisure home shall not exceed 1,7 W/(m2K) (for calculation, see Annex B). 5.8.2 Roof ventilation space Any space immediately below the external roof skin shall be ventilated to the outside air. NOTEThe design of th
39、e wall structure and the materials used should be such that condensation on the surface of the inner walls and partitions can be avoided without the need to raise the inside temperature or increase the ventilation beyond the levels required for health and comfort. Precautions should be taken to mini
40、mize water vapour condensing within the insulating material. 5.8.3 Floor Underfloor insulation, if provided, shall be protected from attack by birds and animals. 6 Construction NOTEMaterials used in the construction of a leisure home should comply with the requirements of relevant International Stan
41、dards and should be of suitable nature and quality. The structure should be rainproof, the floor being proof against moisture rising from the ground. 6.1 Snow loading 6.1.1 Standard grade A standard grade leisure home resting on its normal supports shall be capable of resisting a snow load of 1 800
42、N/m2 exerted uniformly over the roof. 6.1.2 High altitude grade A high altitude grade leisure home resting on its normal supports shall be capable of resisting a snow load, or pressure of snow on the roof, (so), in newtons per square metre, exerted uniformly over the roof, determined from the follow
43、ing formula: where h is the altitude in metres. 6.1.3 Extra-high altitude grade An extra-high altitude grade leisure home resting on its normal supports shall be capable of resisting a snow load, or pressure of snow on the roof, (so), in newtons per square metre, exerted uniformly over the roof, det
44、ermined from the following formula: where h is the altitude in metres. 6.2 Wind loading A leisure home (all grades) shall be provided with suitable holding-down points if, when resting on its normal supports, it is not capable of resisting, without overturning, a wind velocity of 30 m/s (108 km/h),
45、measured 3 m above the ground, corresponding to a mean dynamic pressure of 315 N/m2. The method of calculation of its resistance to overturning, the overturning force and the factors involved are set out in Annex A. 6.3 Prevention of decay and corrosion 6.3.1 Timbers Where directly exposed to the we
46、ather or used in a situation where intermittent wetting can occur, timber and related timber products shall be either inherently resistant to decay or be treated with a wood preservative. 6.3.2 Metals Iron and steel components exposed to the weather or in a hostile environment shall be protectively
47、coated against rusting. Where bimetallic corrosion is likely, the contact faces of dissimilar metals shall be electrically insulated from one another or be effectively sealed against the ingress of moisture. 6.4 Mobility Permanent mobility of a leisure home shall be provided by wheels or skids and t
48、here shall be a means of attachment to a towing vehicle.
