23、121:2000 BSI 09-2000 3.2 Bow Maximum deviation of the long edge of a door leaf measured in accordance with EN 952. According to its orientation, it can be positive or negative, see figure 1 1 Face 1 2 Face 2 3 Negative bow 4 Positive bow 5 Datum line as defined in EN 952 Figure 1 - Definition of pos

24、itive and negative bow 4 Principle The test is carried out by subjecting the doors to two different climates on either side for a period of time, and measuring the resulting bow of the longitudinal lock side edge at stages of the test. If required, the operating forces and the air permeability of th

25、e doors in their deformed state are also determined. 5 Apparatus 5.1 Basic equipment The test facility shall consist of at least: - a climate chamber or enclosure in which the required climatic conditions on the cold side can be maintained and adjusted within the stipulated tolerances; - an opposite

26、 climate chamber or enclosure in which the required climatic conditions on the warm side can be maintained and adjusted within the stipulated tolerances; - a frame for supporting the doors, which is sufficiently rigid that it will not be significantly deformed by any force that may be transmitted fr

27、om the door leaf to the door frame; - a device for measuring bow; - a device for determining the operating forces in accordance with EN 12046-2 during exposure to the climatic stress.Page 4 EN 1121:2000 BSI 09-2000 5.2 Supplementary equipment - a bank of filament infrared lamps (see informative Anne

28、x A) for heating face 2 of the door. The power of the apparatus shall be such that the surface temperature 3shall be reached within 2 hours and maintained afterwards within a range of 5 C. The filament infrared lamps shall be positioned in such a way that the emitted radiation energy is distributed

29、as evenly as possible over the door leaf. (See Annex A). - Reference surfaces, having an absorption coefficient a sin the visible field (0,4 m to 0,7 m) of at least 0,90 and a thermal resistance of between 0,1 Km/W and 0,2 Km/W, each consisting of an aluminium sheet with matt black finish, mounted o

30、n polystyrene thermally insulating material (extruded; lambda 0,03 W/mK) having a thermal resistance between 0,6 Km/W and 0,7 Km/W, and incorporating a temperature sensor; NOTE 5 mm thickness of polystyrene is usually adequate. - a device for measuring the surface temperatures of the door leaf; - a

31、device, installed in the climatic chamber, for determining the air permeability of the door between the test chambers in accordance with EN 1026; or - a device for deforming the door leaf mechanically, when determination of the air permeability of the doorset is carried out outside the climatic test

32、 chambers. NOTE Annex B gives an example of such a device. 6 Preparation 6.1 Orientation of the doors The orientation of the faces of the door shall be defined by the manufacturer prior to its installation in the test chamber. (See also tables 1 and 2). Closing side = face 1, if the door normally op

33、ens outwards, or Closing side = face 2, if the door normally opens inwards. If this information is missing, the door shall be tested in the orientation least favourable for the classification. NOTE Which orientation is least favourable for the classification depends on the test required. One orienta

34、tion may be worse for operating forces and the other for air permeability. It may therefore be necessary to test the door in both orientations.Page 5 EN 1121:2000 BSI 09-2000 6.2 Mounting If possible, the door and its frame shall be mounted in the test facility in accordance with the manufacturers n

35、ormal fixing instructions. However, the door frame shall be fixed in such a way that its bow does not exceed 1,0 mm under test. 6.3 The doors closing condition 6.3.1 During exposure to the climates The door shall be latched and unlocked, unless this is inconsistent with the hardware of the door set.

36、 6.3.2 When determining bow The bow shall be determined with the door unlatched. NOTE This means that the door is slightly open and that the door leaf is under the minimum stress. If the bow of the door leaf is measured in a different state, this shall be recorded and the reasons given. 6.3.3 When d

37、etermining air permeability If the air permeability of the door is to be measured, this shall be done with the door closed and locked. 7 Measurement methods and accuracy 7.1 Bow The bow of the door leaf shall be measured in accordance with the procedure specified in 4.2 of EN 952. The deviation shal

38、l be measured and recorded to an accuracy of 0,1 mm. 7.2 Operating forces The operating forces shall be determined in accordance with EN 12046-2 when specified in the test procedure. Each determination of operating forces shall be completed before the loss of bow has exceeded 10 % of the bow measure

39、d previously. 7.3 Air permeability If required, air permeability shall be measured in accordance with EN 1026 when specified in the test procedure. Alternatively, the air permeability may be determined away from the climatic test facility provided that the door is maintained in its deformed conditio

40、n within 10 % (e.g. as shown inPage 6 EN 1121:2000 BSI 09-2000 Annex B). For this the door leaf is deformed mechanically in such manner as to reproduce the bow caused by the climatic stress. NOTE 1 It is recommended that all air permeability checks are carried out in the climate chambers without mov

41、ing the frame of the test specimen. If during the determination of the air permeability the bow of the door leaf has changed by more than 10 %, the bow shall be reset by changing the pressure applied to the jack, and the measurement of air permeability repeated. This shall be carried out either in t

42、he climate chambers or outside. If the measurement of air permeability is carried out outside the climate chambers, the loss of bow of the leaf shall not exceed 10 % of the bow measured previously. If necessary, the closing edge of the leaf shall be deformed mechanically with an appropriate device s

43、o as to reproduce the bow measured previously. NOTE 2 Annex B shows an example of such a device. 8 Test conditions Table 1 - Test climate a to d Test climates Required climates Side 1 Side 2 Air temperature ( 1) C Relative humidity ( 1) % Air temperature ( 2) C Relative humidity ( 2) % a 23 2 30 5 1

48、temperatures shall be measured to an accuracy of 0,5 C, within planes parallel to each face of the door leaf, at a distance of (100 50) mm. They shall be measured at 3 points, at least, located in the centre of the door leaf and symmetrically to the vertical axis of the door leaf, within 100 mm of t

49、he top and the bottom of the leaf. If more points are measured, they shall be arranged symmetrically to the vertical and horizontal axes of the door leaf. The average of the results from all the measuring points on each face shall be taken as the temperature of the climate applied on that face. NOTE This procedure does not apply to the measurement of the surface temperature when heating is achieved by radiation (face 2 in climate “e”). In this case, the procedure for measuring
