Dimensions of test samplesTo be representative of a range, the samples submitted for test shall be of the following dimensions (seefigure 1): the maximum width associated with the greatest height achievable with this width, and maximum height associated with the greatest width achievable with this height,the two tests being necessary for a same range.Products of a smaller width and a lesser height than the test samples will be deemed to satisfy the test for theclass.In the case of the conservatory blind, the height to be considered is the maximum free height between theroller tube and the front profile, or between these and the relieving rollers.In the case of the marquisolette, the height to be considered is the total height, the sum of the length of therelieving rail and the height of the vertical part.In the case of folding and trellis arm awnings, the maximum width for one pair of arms is the basis of the test.4.2Laboratory conditionsThe tests are carried out at room temperature of 23°C
