scope:
This Japanese Industrial Standard specifies the methods for measuring the colour of reflecting and transmitting objects (hereafter referred to as "colour") according to the CIE 1931 standard colorimetric system (hereafter referred to as "XYZ")1) and the CIE 1964 supplementary standard colorimetric system (hereafter referred to as "X10Y10Z10") 2).
When the colour of fluorescent objects is measured, it shall be in accordance with specification of JIS Z 8717.
The XYZ and X10Y10Z10 shall be applied to cases where it is desirable to obtain a good correlation to the visual colour matching in the centrally-viewed fields of angular subtenses between about 1 and about 4 degrees and in the centrally-viewed fields of angular subtenses greater than about 4 degrees.
The methods for measuring the colour in this Standard conform to the methods for measuring the colour specified in the Publication CIE No. 15 : 2004 Colorimetry, third edition.
Notes 1) The standard colorimetric system recommended by Commission Internationale de 1'Eclairage (CIE) in 1931.
2) The standard colorimetric system recommended by CIE in 1964.
