適用范圍：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. It states the properties that shall be taken into account when comparing products. It also specifies the corresponding parameters and classifications to quantify the following properties: — for the thermal comfort: — the solar factor (total solar energy transmittance); — the secondary heat transfer factor; — the direct solar transmittance; — for the visual comfort: — the opacity control; — the night privacy; — the visual contact with the outside; — the glare control; — the daylight utilisation; — the rendering of colours. NOTE For other purposes, more detailed methods using different parameters can be used. Some of the characteristics (e.g. gtot) are not applicable when products are not parallel to the glazing (e.g. folding-arm awnings). This European Standard is not applicable to the products using fluorescent materials.
