31、g the test (see Figure 1). This can be done either by the back wall itself or by a flat cooling surface (emission coefficient has to be at least 0,9) covering the whole width and height of the room placed in front of the back wall of the closed test room in accordance with EN 442-2. The space betwee

33、trench and the intended covering is installed in the booth floor in front of this cooling surface, flush with the finished floor level, in accordance with the manufacturers instructions. Unless other dimensions have been given by the manufacturer, the distance between the trench and the cooled back

34、wall shall be 0,05 m (see Figure 2). For the purposes of the test, the trench in itself is covered with a thermal insulation shown in Figure 2 which has a thermal resistance of at least R =1,0 m2K/W. If the floor of the test booth is cooled then the floor has to have a thermal resistance of at least

35、 R =2,5 m2K/W. If the floor of the test booth is not cooled then there is no requirement for such a thermal resistance.
