Champ d’application

This standard applies to the design, production, and installation of safety signs and safety markings in production, business, and public places where safety risks exist. It is mandatory for all manufacturing facilities, construction sites, and public venues within China. It explicitly excludes traffic signs used in railway, road, inland river shipping, maritime, and air transportation. Additionally, it covers the basic identification colors and symbols for industrial pipelines transporting gases and liquids.

Exigences techniques

The standard specifies the color representation for safety information, strictly defining four safety colours (red, yellow, blue, green) and two contrast colors (black, white) with specific chromaticity boundaries. It defines four primary types of safety signs: warning signs (triangles), prohibition signs (circles with a diagonal line), mandatory action signs (circles), and informational signs (squares). Manufacturers must follow strict geometric proportions and graphical symbol designs provided in the standard's normative appendix. For textual auxiliary signs, the standard mandates the use of specific font types (Heiti for Chinese) and capitalization rules for English text. It also dictates material quality, requiring signs to be made of durable, non-flammable materials, with insulation properties required in electric shock hazard zones. Facilities must select sign dimensions based on observation distance and install them at specific angles to ensure visibility. A major component of this standard is the inclusion of industrial pipeline identification requirements. It assigns eight basic identification colors to specific substances (e.g., water, steam, acids, flammable liquids) and mandates the use of identification symbols indicating substance names and flow direction. Pipelines containing hazardous chemicals must be marked with specific yellow and black hazard bands.

Méthodes d’essai

The standard references specific colorimetric boundaries and provides color sample comparisons using systems like RAL, Munsell, and NCS to verify that the manufactured safety colours fall within the acceptable chromaticity zones. Visual inspection protocols are also outlined to verify geometric design accuracy, sign legibility at various distances, and material durability under environmental conditions.

Questions fréquentes

What products and facilities are regulated under GB 2894-2025?

GB 2894-2025 applies to the design, production, and installation of safety signs in production, business, and public places with safety risks. It does not apply to traffic signs used in railway, road, inland river, maritime, or air transportation.

Are there any significant updates from the previous versions of GB 2894?

This version integrates three previous standards (GB 2893-2008, GB 2894-2008, and GB 7231-2003) into a single comprehensive document. It adds 37 new graphical signs, updates 34 existing signs, and introduces specific requirements for industrial pipeline identification and safety signs in poorly lit environments.

How does GB 2894-2025 differ from international ISO standards?

The standard references international guidelines such as ISO 3864-1 and ISO 7010 for design principles and registered safety signs. However, manufacturers must strictly adhere to the specific graphical symbols, color coordinates, and Chinese text auxiliary rules defined in GB 2894-2025 for the Chinese market.

The summary above provides a high-level overview of GB 2894-2025. To ensure complete compliance for your products and facilities entering the Chinese market, a precise and professional translation of the full technical specifications is essential.
