Approved by the State Bureau of Technical Supervision on May 19, 1995 and implemented on May 1, 1996. 2 Eye-catching
GB/T15566-1995
Signs should be placed in places where people can see them most easily. Ensure that the sign is of sufficient size and has a clear contrast with the background.
5.3 Convenience
5.3.1 From the perspective of convenience, the information required by people when they first arrive in a new environment or encounter an emergency should be examined according to the normal flow of personnel. 5.3.2 Guide signs and prompt signs should be used in combination. Guide signs should be used when far away from the target. Prompt signs should be used at the mouth of the sign for easy identification.
5.4 Coordination
5.4.1 Signs should Coordinate with the surrounding environment. The material, color (for public information graphic signs) and setting style of the sign should be selected according to the surrounding environment, so that the sign can increase the beauty of the environment after it is set. 5.4.2 The signs in the same place should be coordinated with each other, and the height, size, material and color (for public information graphic signs) of the signs set in different places should be kept uniform as much as possible. 6 Setting requirements
6.1 Setting method
The setting methods generally used for graphic signs are: attachment (such as nail hanging, pasting, inlaying, etc.), hanging, placement, pole (on objects such as sign poles or brackets), and other setting methods. 6.2 Readability
6.2.1 The offset distance of the sign should be as small as possible. For the observer at the maximum observation distance, the end shift angle should not exceed 15\ (see Figure 1). If the conditions are limited and this requirement cannot be met, the size of the sign should be appropriately increased. 6.2.2 The observation angle of the sign should be as close to 90° as possible. For the observer at the maximum observation distance, the viewing angle should not be less than 75° (see Figure 1).
6.2.3 There should be no fixed obstacles (such as billboards, etc.) that hinder people's reading in front of or near the sign. And try to avoid being blocked by other temporary objects.
6.2.4 The sign band should not be set on movable objects such as doors, windows, and shelves, so as to avoid people from not being able to see the sign after the object moves.

6.3.1 The sign should be set in a bright place to ensure that people can recognize the sign normally. If the expected bright place cannot be found near the location where the sign should be set, consider adding auxiliary light sources or using light boxes. 6.3.2 After the signs made of various materials with specified colors are illuminated by light sources, the colors of the signs should still comply with the provisions of the relevant safety color standards.
6.4 Proper installation
GB/T15566-1995
Try to display the necessary information with appropriate signs to avoid omission and excessive installation. 6.5 Installation location
6.5.1 Guidance signs should be installed at a location that is convenient for people to choose the target direction, and arranged according to the best route to the target. If the target is far away, it can be appropriately installed densely. The signs should be installed at all the designated places. 6.5.2 Warning signs should be installed above or on the side of the facilities and units to be explained, or in a place close to the facilities and units that can attract public attention.
6.5.3 Environmental information signs should be installed at the entrance or the most conspicuous place in a certain place. 6.5.4 Warning signs should be installed in a conspicuous position near the equipment or place to be explained (prohibition, warning, instruction). 6.6 Installation height*
6. 6.1 The installation height of the sign of the attached type is: a
Approximately the same as the height of the human eye level;
Slightly higher than the height of the human body;
Other obviously higher positions, but should meet the requirements of Articles 6.2.1 and 6.2.2; d The installation height of the upper information sign can be determined according to the objective conditions of the site. 6.6.2 The lower edge of the sign of the hanging type should not be less than 2m from the ground. Road traffic signs should be installed according to the specified clearance height.
6.6.3 The lower edge of the sign of the style installation should be about 2m from the ground. If it is confirmed that the location of the sign will not cause harm to the human body due to its setting height, its setting height can be roughly consistent with the height of human eyes or other appropriate setting heights can be selected. Note: The setting height of the 21 "11\ sign shall comply with the provisions of Article 6.10.1 of CB1563C Fire Safety Sign Setting Requirements. 6.7 Direction of Graphic Signs
6.7.1 When setting graphic signs with directionality, avoid conflicts between their direction and the direction of the actual scene (see Figure 2). The mirror of the sign can be used
GB/T15566--1995
6.7.2 If the graphic sign in the guide sign contains a directional feature, its direction should be consistent with the direction indicated by the arrow (see Figure 3 (a)). If it is inconsistent, the direction of the graphic sign should be changed (such as using its mirror image, see Figure 3 (b)). 6.7.3 When setting a prohibition sign, the negative straight bar in the sign should be at a 45° central angle to the waterline.
