For undated references, the latest version (including all modification orders) applies to this document. GB/T 5700-2008 Lighting Measurement Methods. GB/T8424.1 Textiles - Tests for Color Fastness - General Principles for the Determination of Surface Color - FZ/T01047 Standard Light Source Conditions for Visual Evaluation of Textile Color Fastness - Terms and Definitions -3. The terms and definitions defined in GB/T 5700-2008, FZ/T 01047, and the following apply to this document. 3.1 Appearance inspection refers to the process of evaluating the appearance quality of an object using sensory or instrumental methods under certain lighting conditions, comparing standard materials and requirements. 3.2 Illuminance. The illuminance at a point on the surface is the quotient of the luminous flux incident on the surface containing that point pided by the area of that surface, expressed in lux (1x). [GB/T 5700-2008, Definition 3.1] 3.3 Related Color Temperature When the chromaticity point of the light source is not on the trajectory of the complete radiator (blackbody), and the chromaticity of the light source is closest to that of the complete radiator (blackbody) at a certain temperature, the absolute temperature of the complete radiator (blackbody) is called the relevant color temperature of the light source, in Kelvin (K). [GB/T 5700-2008, Definition 3.5] 3.4- General color rendering index The general color rendering index determines the degree to which the color of an object perceived under a given light source corresponds to the color of the same object perceived under a standard light source under specified observation conditions
