Glass Plate Analysis in Accordance with JIS R3106

Introduction

The methods for determining visible light transmittance, or simply visible transmittance, visible reflectance, solar transmittance, solar reflectance and solar energy absorbance, and normal emittance and their respective methods of calculation are specified in JIS R3106 “Testing Method on Transmittance, Reflectance and Emittance of Flat Glasses and Evaluation of Solar Gain Coefficient”. Of these indices, which express the characteristics of plate glass, solar transmittance and its determination was introduced in Application News A396. The remaining plate glass indices are introduced here.
