Besides JIS R3106, which is related to flat glass, there are other solar measurement-related JIS standards: JIS A5759 regarding films for glazing used in construction and JIS K5602 regarding paint films. %PDF-1.4 Please contact us to check the availability of these products in your country. 0 Calculation of the visible transmittance, visible reflectance, solar transmittance, and solar reflectance was conducted using the solar transmittance measurement software shown in Fig. Commercial spreadsheet software was used to calculate normal emittance. Though calculations based on JIS standards can also be performed by commercial spreadsheet software, calculation results can be obtained more easily by using dedicated software such as the Solar Transmittance Measurement Software shown in Fig. %�쏢 To determine normal emittance, specular reflectance (ρn(λ)) measurement is conducted in the infrared region 2000 to 400 cm-1 using an IR spectrophotometer equipped with a specular reflectance measurement attachment. SRI is defined to be zero for a clean black roof (with a solar reflectance of 0.05 and a thermal emittance of 0.90) and 100 for a clean white roof (with a solar reflectance of 0.80 and a thermal emittance of 0.90) (Akbari and Levinson, 2008).

Table 2 shows the visible transmittance, visible reflectance, solar transmittance, solar reflectance, and normal emittance of each calculated sample. E1980 Practice for Calculating Solar Reflectance Index of Horizontal and Low-Sloped Opaque Surfaces. Also, if the measurement wavelength of 50 μm (200 cm-1) cannot be attained, the specular reflectance value at the measured upper limit wavelength is used as the value for longer wavelengths. Solar Reflectance. Close to parallel beam of light incident from the normal direction, Close to parallel beam of light incident from the radiation slit at an angle not exceeding 15°, Irradiation at an angle not exceeding 15°, The air layer is used as the standard sample, and its spectral transmittance is taken to be 1, Specular reflector of reflectance specified by the absolute reflectance measurement method (sample 1), or specular reflector of reflectance specified by comparison with the sample 1, Aluminum-coated mirror with certified absolute reflectance.
