VERIFICATION OF THE SPECIMEN The materials and components used were inspected during assembly on the basis of the supplied drawings and data. Efectis Nederland BV was not involved with the production of the components. The assembled element (glass excluded) was sampled by notified body Efectis Nederland BV, Netherlands, notified body number 1234 (sampling file reference: 2014-Efectis- R000826) CONDITIONING From the moment of installation until the fire test, the construction was stored in the laboratory of Efectis Nederland BV under the following conditions: Ambient temperature: 20 ± 5 C. Relative humidity: 50 ± 10 % FIRE TEST Test conditions The test was performed under the conditions as specified in EN , EN , EN and pren The frame construction was heated according to the standard fire curve, See figure A.1. During the heating the ambient temperature fulfilled the requirements of EN The desired furnace pressure was maximum 20 Pa at the top end of the test specimen. Due to the desired furnace pressure, the pressure set at a height of 2.5 m above the furnace floor level was 14.5 Pa. See figure A Measurements During the heating, the following conditions of the furnace, specimen and surroundings were measured and registered: Furnace conditions: Gas temperatures inside the furnace with fifteen plate thermocouples (Tov1 to Tov15), evenly distributed over the directly heated surface (see figure A.1); The pressure in the furnace, at a height of 2.5 meters measured above the furnace floor level (see figure A.3).

14 7. FIELD OF DIRECT APPLICATION This report details the method of construction, the test conditions and the results obtained when the specific element of construction described herein was tested following the procedure outlined in EN , and where appropriate EN Any significant deviation with respect to size, constructional details, loads, stresses, edge or end conditions other than those allowed under the field of direct application in the relevant test method is not covered by this report GENERAL The results of the fire test are directly applicable to similar constructions where one or more of the changes listed below are made and the construction continues to comply with the appropriate design code for its stiffness and stability. Other changes are not permitted. Decrease in the linear dimensions of panes; Change in the aspect ratio of the panes, provided that the largest dimension of the pane and its area are not increased; Decrease in the distance between mullions and/or transoms; Decrease in distance between fixing centres; Increase in the dimensions of framing members; Screwed-on glazing beads since clip-on glazing beads were incorporated in the test; Allowances for expansion if none were incorporated in the test specimen; Change in the angle of installation of up to 10 from the vertical EXTENSION OF HEIGHT The increase of the element height is not allowed EXTENSION OF WIDTH The width of an identical construction may be increased since the specimen was tested at a minimum of 3 m wide with one vertical edge without restraint STANDARD SUPPORTING CONSTRUCTIONS Since the single window partition was tested in an aerated concrete standard supporting construction, given in EN , the results of the fire test are applicable to any other supporting construction within the same type (low density rigid supporting construction) that has a greater fire resistance.
