Blinds and shutters - Thermal and visual comfort - Test and calculation methods

Asnjë informacion i shtuar.

This European Standard defines test and calculation methods for the determination of the reflection and transmission characteristics to be used to determine the thermal and visual comfort performance classes of external blinds, internal blinds and shutters, as specified in EN 14501. This European Standard also specifies the method to determine opacity characteristics of dim-out/black-out external blinds, internal blinds and shutters, as specified in EN 14501. This European Standard applies to the whole range of shutters, awnings and blinds defined in EN 12216, described as solar protection devices in this European Standard. Some of the characteristics (e.g. gtot) are not applicable when products are not parallel to the glazing (e.g. folding-arm awnings). NOTE Informative Annex D presents an approach for the determination of characteristics in case of projectable products. Products using fluorescent or retroreflecting materials are outside the scope of this European Standard.
