Application Summary AI generated
GB/T 20151-2026 specifies the CIE system of physical photometry, defining standard procedures for measuring light quantities such as luminous flux, illuminance, and luminance. It is applied in metrology laboratories, lighting product testing, and optical instrument calibration to ensure consistent photometric measurements across industries like automotive lighting, display manufacturing, and general illumination. This standard is critical for compliance testing and quality control of light sources and optical sensors.
