Figure 1- Example of a construction of an adhesive backed polymeric film (interior grade) 5 Properties of adhesive backed polymeric films 5.1 General The properties of adhesive backed polymeric films are wide ranging. Their specific performance characteristics are given below: 5.1.1 Performance characteristics The performance characteristics and the properties of adhesive backed polymeric film are described in relation to their class, i.e. where they can be used, and to their type, i.e. the performance of the glass that will be modified. The class of film is given in Table 1 and Figure 2 and their property modifications are given in Table 2, where surface 1 is always towards the external environment. SIST EN 15752-1:2014

Class D adhesive backed polymeric film is normally an internal film used within the cavity of an insulating glass unit.

B5 – An adhesive backed polymeric film designed to be applied on surface 2 of single glazing, surface 4 of double glazing, or surface 6 of triple glazing, generally known as an internal film, in order to modify the appearance of the glass pane to a decorative product. EXAMPLE 2
D1248 – An adhesive backed polymeric film designed to be applied to surface 2 of double glazing or surface 2 and / or surface 4 of triple glazing in order to modify the solar control, emissivity, privacy and EMI shielding of the glazing. 5.1.2 Test specimens The performance characteristics shall not be determined for the adhesive backed polymeric film alone, unless otherwise specified in this standard; performance characteristics shall be determined using test samples consisting of the adhesive backed polymeric film applied to clear, monolithic, uncoated float glass of nominal thickness of 4 mm. The glass shall be monolithic soda lime silicate and shall be in accordance with EN 572-1 and EN 572-2. One or more tests may be conducted on glass meeting these requirements but with a different thickness; these tests shall only be accepted if the same tests have been completed and reported in accordance with this standard for 4 mm thick glass. The adhesive backed polymeric film shall be applied to the glass substrate in accordance with the original manufacturer’s recommendations. Measurement of the properties of test specimens shall be made after the cure time has elapsed. The adhesive backed polymeric manufacturer should supply cure time requirements. Test specimens shall be representative of normal production material. Where the film shall be installed to a glass substrate in order to perform the test, the installation method shall be representative of the normal method used to install the adhesive backed polymeric film to the glass substrate. 5.2 Solar-optical properties 5.2.1 General Almost all adhesive backed polymeric films can be characterized directly for solar-optical properties. Properties specific to different types of adhesive backed polymeric films are considered in 5.3 to 5.12. The spectrophotometric properties shall be determined in accordance with EN 410 on a sample that is made up of adhesive backed polymeric film applied to clear monolithic float glass of 4 mm thickness, in accordance with the requirements in 5.1.2. If repeat measurements are required in order to obtain average values, measurements shall be made on separate samples prepared and constructed in identical manner. SIST EN 15752-1:2014

Properties of the adhesive backed polymeric film alone can be determined by calculation in accordance with EN 410 using appropriate software. Hence the performance of the filmed glass can be calculated by combining the properties of the adhesive backed polymeric film with those of the glass substrate. NOTE 4 Nominal values are given for the adhesive backed polymeric filmed glass. Due to the inherent variations in the manufacturing processes the measured values may vary from the nominal values. 5.2.2 Glare reduction Glare reduction is the % reduction in visible light transmittance of glazing, given by: Glare Reduction =
VgVfVg100τττ−× where τVg = visible light transmittance through 4 mm clear glass, i.e. 0,89 τVf = visible light transmittance through 4 mm clear glass with adhesive backed polymeric film Visible light transmittances, τv, shall be determined in accordance with EN 410 and in accordance with the requirements in 5.2.1. 5.2.3 Total Solar Energy Rejected Total Solar Energy Rejection (TSER) is the amount of solar energy that is rejected by the glazing to the outside environment; it is calculated from: TSER = (1-g) × 100 % where g is the total solar energy transmittance determined in accordance with EN 410 and in accordance with the requirements in 5.2.1. 5.2.4 UV Rejection UV rejection (UVR) is the percentage of UV radiation that is not transmitted by the glazing and is calculated from: UVR % = 100

(1 – τUV) where τUV is the Ultra-Violet radiation transmittance determined in accordance with EN 410 and in accordance with the requirements in 5.2.1. 5.3 Solar control film 5.3.1 General The purpose of adhesive backed polymeric solar control film applied to glass is reduction of the g value of the glass substrate to which it has been applied. 5.3.2 Measurement Determination of the g value and other solar-optical characteristics shall be determined in accordance with EN 410 and in accordance with the requirements in 5.2.
