The BS 950-1-1967 standard defines the specification of artificial daylight lighting equipment for Color assessment, with an emphasis on the lighting requirements for Color Matching and Color Identification. This standard aims to ensure that the lighting effect of natural daylight is simulated in an artificial environment for accurate Color comparison and determination. The standard specifies key parameters such as light source type, Light spectrum distribution, color temperature, and light intensity of the illuminator to ensure that it meets the scientific and reliability of Color assessment. By following this standard, users can perform Color matching and quality control under stable and consistent lighting conditions, avoiding Color errors caused by differences in environment light. This standard is widely used in Color inspection and control of products in Spinning & Weaving, Coating, Plastic and other industries.
