JAPANESE INDUSTRIAL STANDARD
JSR3106:1998
Testing method on transmittance, reflectanc
and emittance of flat glasses and evaluation
of solar heat gain coefficient
Introduction This Standards is the Japanese Industrial Standard prepared on the ba-
sis of ISO 9050 Glass in building-determination of light transmittance, solar direct
transmittance, total solar energy transmittance and uitra violet transmittance, and re
lated glazing factors, published as the first edition in 1990, without altering the techni
al contents as to the corresponding parts. A part of the specified values (ultraviolet
radiation transmittance and color rendering properties), however, has not been emn
lo
ployed
1 Scope This Japanese Industrial Standard specifies the testing methods to obtain
the transmittance and reflectance for visible light and the transmittance, reflectance
and absorptance for solar radiation, as well as the emissivity of thermal radiation at or
dinary temperature of the flat glasses() for buildings using the spectrophotometer, and
the method to calculate the solar heat gain coefficient when these flat glasses are used
in the windows of building
Note ( The flat glasses mean those as given in the following. However, such
glasses of diffuse transmitting property as the figured glass and the like
are excluded
a)Those flat glasses which have been manufactured by a continuous
moulding process mainly using the soda lime silicate glass as the ma
terial
b) Those which have been processed with optical thin film of wavelength
selective reflection on the surface of a), i .e, the reflecting glass of the
wavelength region of solar radiation such as
