In this standard, the tristimulus values and chromaticity coordinates of the standard colorimetric system of International Commission on Illumination CIE 1964 and CIE 1931, or CIE 1976 L*a*b* chroma space or dominant wavelength (complementary wavelength) and excitation purity are used to express the results. 1 Subject Content and Application Scope This standard specifies the method for measurement of chromaticity for colour building materials. This standard is applicable to the colorimetric measurement of non-fluorescent colour building materials (e.g. new decorative materials such as ceramic, enamel, paint, glass fiber reinforced plastics, glass, cement and wall paper). 2 Normative References GB 3977 Specification of Colors GB 3978 Standard Illuminants and Illuminating-viewing Conditions GB 3979 Methods for the Measurement of Object Color GB 5698 Glossary of Color Terms GB 7921 Uniform Color Space and Color Difference Formula GB 9087 The White Powdered Standard Plate for Colorimetry and Photometry GSB A 67001 Material Standard of Magnesium Oxide Whiteness 3 Terms and Symbols 3.1 Chroma Refers to the color purity or saturation of object. 3.2 Hue value hab The angle of arctan function of (b*/a*) within 0~360°
