Scope: This part of GB/T 2893 specifies the relevant requirements and test methods for the chromaticity and photometric properties of safety signs used in workplaces and public places, and provides color for safety colors and contrasting colors specified in GB/T 2893.1-2013. Specifications for photometry and luminosity. The physical requirements achieved by safety signs are mainly related to daylight color and normal lighting environment. This part also includes chromaticity requirements and test methods for safety signs and phosphorescent materials used in non-illuminated environments. This section applies to all places where personal safety concerns are of concern. This section does not apply to the guidance signal transmission of railway, road, inland waterway, sea and air traffic. In short, it does not apply to areas otherwise stipulated in laws and regulations.
