The provisions contained in the following standards constitute the provisions of this standard through reference in this standard. When this standard is published, the versions shown are valid. All parties who can use this standard are advised to discuss the possibility of using the new versions of the following standards. AN R/2681-14 Building Glass Visible Light Transmittance, Direct Solar Transmittance, Total Solar Energy Transmittance, Ultraviolet Rejection Ratio Changes to the relevant glass parameters (neg15 () 9050: 1990) 3 Definitions
This standard uses the following definitions.
3.1 Transmittance
The ratio of the amount of solar radiation to the amount of radiation transmitted under specific geometric and spectral conditions. 3.2 Air quality (ratio) irmuss (rutio) The ratio of the air quality above the observer to the air quality directly above the observer when the observer is standing at sea level in a standard atmosphere.
3.3 Solar indirect transmittance solarindirccttransmittncc The ratio of the energy re-radiated into the vehicle after being absorbed by the safety glass material to the solar energy absorbed by it. 3.4 Operational convention AcanentinnA
Operational convention A1 stipulates that the range of the exposure distance of F-type ultraviolet light is 300--400m. The air quality is 1.5. 35 Operational convention Convention B
The calculation method of the H stipulates that the wavelength range of the external radiation V is 3(i(mm~38mal, the air quality is 1.4 state resistance to radiation ratio
4.1 Measuring instrument
This method requires the use of a scanning spectrophotometer with an integrating sphere to measure the spectral transmittance of the glass material. Its leakage range exceeds the range of the solar radiation to the earth's night sky (to 300m-~2500m below). 1) The calculation results of the method will be detailed and the technical differences will be different. Therefore, in practice, the applicable date of the application should be clearly stated.
