22、. DIN EN 13420:2011-07 EN 13420:2011 (E) 4 Introduction Through climatic loading of the windows it is possible in the case of unfavourable designs that the frames of windows manufactured of different materials may: decay through accumulation of moisture and may thus be damaged; this moisture may com
23、e from water vapour diffusion and condensation; be unable to fulfil their basic functions (serviceability, air permeability) because of unacceptable deformations. DIN EN 13420:2011-07 EN 13420:2011 (E) 5 1 Scope This European Standard specifies the test methods for evaluating: the risks of decay of
24、openable and fixed windows manufactured of different materials through increased moisture accumulation as a result of condensation or water vapour diffusion; the influence of deformation on basic performances of openable and fixed windows manufactured of different materials exposed to different clim
25、ates between their external and internal faces. Three test methods are to be differentiated. They take into account different cases of loadings. Test method 1: For designs with low resistance to water vapour diffusion (normally designs with water vapour equalization holes); the test procedure is to
26、be used for cross-sections where the danger is given by the moisture accumulation as a result of the condensation of moisture between the planking and the timber (see Annex A (informative), Figure A.1). Test method 2.1 and 2.2: For designs with high resistance to water vapour diffusion (normally des
27、igns without water vapour equalization holes); the test procedure is to be used for cross-sections where the danger is given by the condensation of the moisture between the surface of the inner profile and the inner surface of the outer profile by having a different water vapour diffusion (see Annex
28、 A (informative), Figures A.2 and A.3). Test method 3: For designs being sensitive to deformation; the test procedure is to be used for cross-sections where they are sensitive to the function through deformation as a result of climatic loading. This European Standard defines the test procedures whic
29、h are to be used in dependence of the potential risk of the design. This European Standard is relevant to initial type testing, i. e. to developments or changes in designs. It is not relevant to routine quality control or to proven designs. NOTE Designs are included in Annex A (informative). Annex B
30、 (normative) is the survey of general design criteria where tests are not necessary. 2 Normative references The following referenced documents are indispensable for the application of this document.

34、tions, e.g. through sufficient ventilation NOTE See Annex A (informative) and B (normative). 3.2 design with high resistance to water vapour diffusion design which is regarded as being a design with high resistance to water vapour diffusion when as a result of profile coverings a sufficient draining
35、 of the moisture conditioned by water vapour diffusion is impaired in the combined profile 3.3 design being sensitive to deformation design which is regarded as being sensitive to deformation when under specified service conditions the relative expansion (thermal or hygrometrical) of the profile may
36、 impair the basic functions of the window (e.g. operating forces, air permeability) 3.4 window manufactured of different materials window whose frame (or sash or both) members are manufactured of non-identical materials, operating hardware being excluded EXAMPLES Typical examples: basic timber windo

38、t visible moisture accumulation, after climatic exposure, at the interface between timber (or any other hygroscopic materials) and another material 4 Principle of tests 4.1 Vapour diffusion In order to have a temperature below dew point in composite profiles, a gradient of water vapour diffusion and
39、 a gradient of temperature are created; the window is exposed to this double gradient for a specified time during which the water content of hygroscopic elements is checked. DIN EN 13420:2011-07 EN 13420:2011 (E) 7 4.2 Stability A gradient of temperature between the 2 sides of window is created and
40、the window is exposed to this gradient for a specified time and measurement of deformations and functional deformations are carried out. 5 Test facility The test facility is defined in EN 1121. In addition the following test facilities are required: a measuring device for determining the moisture co
41、ntent; an electric hygrometer which is properly calibrated for determining the moisture content of the timber and which has to have an accuracy of 1 %; and a measuring device for determining the deformation with an accuracy of 0,1 mm. 6 Dimensions of the test specimens For the test methods 1 and 2 t
42、he test results are independent of the dimensions. For that reason, the dimension can be agreed upon between the test laboratory and the applicant. In the case of designs sensitive to deformation (test method 3) the largest overall dimension foreseen by the manufacturer is to be tested to ensure the
43、 validity of the test. The test results obtained at the foreseen maximum dimensions of the tested profile system can be extrapolated to smaller width and height without additional testing. 7 Preparation for test The test specimen shall be mounted taking into account the installation instructions as
44、defined and published by the manufacturer. The test specimen shall be fixed in the test rig plumb without any twists or bends, which may influence the test results. The specimen shall be fully operable and shall be opened and closed five times before the test. During the test the windows shall be se
45、cured in a closed and locked position. 8 Test conditions The test conditions subsequently listed shall be used in connection with the test methods in Clause 9.
