1 Scope
This part of GB/T 2893 establishes the safety identification colours and design principles for safety signs to be used in workplaces and in public areas for the purpose of accident prevention, fire protection, health hazard information and emergency evacuation. It also establishes the basic principles to be applied when developing standards containing safety signs.
This part is applicable to workplaces and all locations and all sectors where safety-related questions may be posed. However, it is not applicable to the signalling used for guiding rail, road, river, maritime and air traffic and, generally speaking, to those sectors subject to a regulation which may differ.

3 Terms and Definitions
For the purposes of this part of GB/T 2893, terms and definitions established by GB/T 15565 and the following terms and definitions apply:
3.1
Coefficient of retroreflection
R′
<Plane retroreflecting surface> luminous intensity (I) of a plane retroreflecting material in the direction of observation divided by the product of the illuminance (E⊥) of the retroreflecting surface on a plane perpendicular to the direction of the incident light and its area (A)
