Compliance-Überblick

Dieser Überblick ist derzeit nur auf Englisch verfügbar.

Geltungsbereich und Anwendbarkeit

This standard applies to the design, classification, and installation of traffic safety signs set up in China's inland navigable waters. It covers various infrastructures including riparian-based signs on riverbanks, bridge signs on over-water structures, and wading signs on in-water constructions. It is mandatory for all maritime safety administrations, bridge constructors, and waterway facility managers operating in Chinese inland waters.

Technische Anforderungen

The standard classifies inland waterway signs into riparian-based, bridge, and wading signs based on their installation locations. Riparian-based signs are further divided into main and auxiliary signs, functioning as warning, prohibition, mandatory, and informational signs. The standard specifies the shapes, dimensions, and color schemes for each category, ensuring visual consistency across different waterway grades. Manufacturers must strictly adhere to the specified color ranges and geometric proportions for sign production. For bridge signs, the standard details requirements for bridge warning signs (Type A and Type B) and bridge informational signs, such as real-time clearance height scales and bridge name plates. It specifies the use of red and white 45-degree stripes to mark navigable spans clearly. These bridge markings are critical for preventing vessel collisions with underwater piers and superstructures. The standard also outlines requirements for wading signs, including warning piles and real-time clearance/water depth scales. Additionally, it introduces specifications for changeable-message signs used in high-traffic or hazardous waterways to display dynamic navigational information, weather conditions, and real-time bridge clearances. The color coding for these dynamic displays must align with the static sign categories (e.g., yellow for warnings, red for prohibitions).

Prüfverfahren

While primarily a design and installation standard, compliance involves verifying the colorimetric properties of sign materials against the chromaticity coordinates specified in Appendix A. This includes testing surface colors and retroreflective materials. Additionally, the physical dimensions and structural integrity of sign panels and supports must be verified against the specified geometric grids and load requirements. Manufacturers must ensure retroreflective films meet the performance criteria outlined in referenced standards like GB/T 18833.

Häufige Fragen

What products and facilities are regulated under GB 13851-2022?

GB 13851-2022 applies to traffic safety signs installed in China's inland navigable waters. It covers riparian-based signs, bridge signs, and wading signs used to regulate and guide maritime traffic.

Are there any significant updates from the previous GB 13851-2019 version?

The 2022 version introduces new terms and categories, including real-time navigation clearance height and specific signs for wading structures. It also adds new warning signs for fog and high winds, and details requirements for bridge and wading signs.

How does GB 13851-2022 relate to other standards?

The standard references several national standards, such as GB 2893 for safety colors and GB 50139 for inland navigation standards. While it shares conceptual similarities with international maritime signage, it specifies unique design codes and dimensional requirements tailored to China's inland waterway classifications.
