Foreword

This standard replaces GB/T 5433-1985 "daily glass transmittance measurement method." This standard and GB/T 5433-1985 differences. --- Measuring range. Determination of visible light transmission originally colorless glass daily, daily modified light transmittance of the glass products Determination. --- Original light transmittance T (%) = I/I0 × 100 (400nm ~ 700nm, 7 points) after the average value, is modified τ Vp = 780nm 380nm τ (λ) Vp (λ) SD65 (λ) Δλ 780nm 380nm Vp (λ) SD65 (λ) Δλ (380nm ~ 780nm, 10nm wavelength interval value superposition). --- The thickness of the sample (2 ± 0.15) mm to (2 ± 0.1) mm. --- Requested by the sample surface with a surface roughness finish instead represented. --- Removed the sample plane parallelism 0.04mm requirements. Appendix A of this standard is a normative appendix. The standard proposed by China National Light Industry Council. This standard by the National Standardization Technical Committee household glass. This standard was drafted. Donghua University, the National Optical glass enamels Quality Supervision and Inspection Center. The main drafters of this standard. Yang Jianrong, Wangxian Ying. This standard replaces the standards previously issued as follows. --- GB/T 5433-1985. Daily glass light transmittance ratio measurement method

3 Terms and Definitions

The following terms and definitions apply to this standard. 3.1 On the human visual system to produce bright colors and feeling of electromagnetic radiation, electromagnetic radiation known as visible. The wavelength range is generally taken 380nm ~ 780nm. 3.2 τ (λ) Glass spectral transmittance τ (λ), with a wavelength of [lambda], the ratio of the transmission spectrum of the glass flux and the incident spectral flux. 3.3 τ Vp Light transmittance τ Vp under D65 light source, through the glass of the ratio of luminous flux and the incident flux. Glass light transmittance (τ Vp) Mathematics Expressions such as formula (1). τ Vp = 780nm 380nm τ (λ) Vp (λ) SD65 (λ) dλ 780nm 380nm Vp (λ) SD65 (λ) dλ (1) Where. --- [lambda] the wavelength in nanometers (nm); τ (λ) --- the spectral transmittance of the glass; Vp (λ) --- Visual Spectrum luminous efficiency function; SD65 (λ) relative spectral power --- standard illuminant D65 light source distribution.
