These tests are intended to simulate the most onerous conditions, for the relevant characteristics. 5 Design and construction 5.1 Occupancy The manufacturer shall designate the occupancy as the number of berths provided, both standard and additional berths, provided by the manufacturer and shall include it in the users 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.

Windows 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). 5.4 Doors At least one exterior door which opens outwards shall be provided. 5.5 Glazing Glass in windows, panels and doors that is less than 800 mm above finished floor level shall be safety glazing. 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: 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 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 at both ends of the roof. If space allows, one high level and one low level ventilator shall be provided at both ends. 5.9 Floor Underfloor insulation, if provided, shall be protected to reduce the possibility of degradation by birds or
