适用范围：This European Standard specifies the test methods for evaluating: the risks of decay of openable and fixed windows manufactured of different materials through increasedmoisture accumulation as a result of condensation or water vapour diffusion; the influence of deformation on basic performances of openable and fixed windows manufactured ofdifferent materials exposed to different climates 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 watervapour equalization holes); the test procedure is to be used for cross-sections where the danger is givenby the moisture accumulation as a result of the condensation of moisture between the planking and thetimber (see Annex A (informative), Figure A.1). Test method 2.1 and 2.2: For designs with high resistance to water vapour diffusion (normally designswithout water vapour equalization holes); the test procedure is to be used for cross-sections where thedanger is given by the condensation of the moisture between the surface of the inner profile and the innersurface of the outer profile by having a different water vapour diffusion (see Annex 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 crosssectionswhere they are sensitive to the function through deformation as a result of climatic loading.This European Standard defines the test procedures which are to be used in dependence of the potential riskof the design.This European Standard is relevant to initial type testing, i. e. to developments or changes in designs. It is notrelevant to routine quality control or to proven designs.NOTE Designs are included in Annex A (informative). Annex B (normative) is the survey of general design criteriawhere tests are not necessary.
