This European Standard shall be given the status of a national standa

14、rd, either by publication of an identical text or by endorsement, at the latest by December 2004, and conflicting national standards shall be withdrawn at the latest by December 2004. It is part of a series of standards for windows. This document supersedes 8.2.2 Racking of EN 107:1980. Annex A is n

15、ormative. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy,

16、Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. EN 14608:2004 (E) 4 1 Scope This European Standard specifies the determination of resistance to racking of an open casement or sash expressed as loads a

17、nd the resulting maximum and residual deformations. This European Standard applies to the opening modes specified in Figure A.1 to Figure A.6 and included in EN 12519. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These

18、normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated

19、references the latest edition of the publication referred to applies (including amendments). EN 12519, Windows and pedestrian doors Terminology. 3 Terms and definitions For the purposes of this European Standard, the terms and definitions given in EN 12519 apply, together with the following: 3.1 rac

20、king static load applied in the plane of the casement or sash 4 Apparatus A surrounding substantial steel frame with movable steel supports 1 )into which the sub-frames containing test specimens of various dimensions can be mounted. Means for the application of forces with an accuracy of 5 % uniform

21、ly and without shock. An analogue or digital measuring instrument for determining measurements with an accuracy of 0,1 mm. 5 Test specimen The test specimen shall be supplied in a fully operable condition. It shall be suitable for fixing into the surrounding frame in accordance with the manufacturer

22、s published recommendations or standardised instructions. 1) A suitable frame would, for example, be of such stiffness that the mid span deflection of any member of the frame does not exceed 1/500 of its unsupported length under the action of a force of 1 kN applied at any point or direction perpend

23、icular to the length of that member. EN 14608:2004 (E) 5 6 Conditioning and preparation of the test specimen 6.1 Conditioning Storage and testing shall be carried out in a non-destructive environment within the ranges of 10 C to 30 C and 25 % to 75 % relative humidity. 6.2 Preparation Remove all tra

24、nsport blocks, bracings, packaging and protective wrappings from the test specimen. The test specimen shall be mounted level, square and without visible twist resulting from the use of fixing devices. 7 Procedure When carrying out the test (see Figure A.7) the following shall be taken into account.

25、Having disengaged any restricting devices, open and close the test specimen five times before the test to its maximum extent or 90, whichever is greater. For windows with more than a single leaf the first test shall be to the main leaf. When testing multi-function windows such as those that tilt and

26、 turn, each function shall be tested separately. The most common usage shall be tested first (e. g. tilt before turn). In the case of sliding sashes, block one lower corner edge to prevent sliding when the load is applied. To take up any slack in hinges or pivots, if fitted, apply a pre-load of 10 %

27、 of the maximum test load or a minimum of 20 N according to Figures A.1 to A.6. Remove the pre-load and measure the deformation (a 0 ). Apply the static test load F according to Figures A.1 to A.6 and measure the deformation (a 1 ) under the test load. Remove the test load and measure the deformatio

28、n (a 2 ). Apply and remove all loads continuously to avoid dynamic effects. Apply the loads in increments of a maximum of 100 N and over a minimum of 1 s for each increment. 8 Expression of results Note the loads, together with the maximum (a 1 a 0 ) and residual (a 2 a 0 ) deformations measured dur

29、ing the test. Express loads in Newtons (N) to three significant figures and deformations in millimetres (mm) to two significant figures. 9 Test report The test report shall contain at least the following information: a) reference to this European Standard; b) name of the test laboratory; c) name of

30、the manufacturer and applicant; d) date of test and test report; e) all relevant details for identifying the test specimen and apparatus type; specified dimensions; materials; form and mode of opening; f) test results; g) permanent damage to the test specimen.
