Champ d’application

This standard is applicable to the production, distribution, usage, and supervision of geographical name signs in China. It covers signs for both natural geographical entities (such as seas, water systems, and terrains) and human geographical entities (including residential areas, administrative regions, and facilities). It is mandatory for all manufacturers and suppliers of geographical name signs entering the Chinese market. The standard replaces the previous GB 17733.1-1999 and introduces new categories and technical requirements.

Exigences techniques

The standard specifies comprehensive requirements for geographical name signs, focusing on layout, materials, and durability. Key aspects include: - Layout and Content: The standard mandates specific proportions for text and Pinyin placement, such as the upper 3/5 area for Chinese characters and the lower 2/5 for Pinyin. It also specifies requirements for minority languages and graphical symbols. - Material and Performance: Signs must meet stringent basic performance criteria, including resistance to salt spray, humidity, high and low temperatures, and weathering. The base materials must possess adequate hardness and impact resistance. - Special Features: For signs with special functionalities like reflective, long-afterglow luminescent, and LED features, the standard sets specific performance benchmarks. For instance, LED signs must meet minimum brightness levels and electrical safety standards, including insulation resistance and withstand voltage. - Safety and Installation: The standard outlines requirements for support structures, ensuring they are corrosion-resistant and securely installed. Manufacturers must ensure that signs do not pose any physical or environmental hazards.

Méthodes d’essai

The standard details various testing methods to verify compliance: - Environmental Resistance Tests: Including salt spray corrosion, humidity and heat, high temperature, and low temperature tests to ensure durability under harsh conditions. - Weathering Test: Utilizing a xenon lamp weathering tester to simulate prolonged exposure to sunlight and rain. - Radiation Test: Measuring α, β, and γ radiation levels to ensure they do not exceed twice the background reading. - Impact Resistance Test: Using a drop ball impact tester to assess the structural integrity of the signs. - Luminance and Electrical Safety Tests: For LED and luminescent signs, tests measure initial brightness, afterglow luminance, and electrical safety parameters like insulation resistance and withstand voltage.

What products are regulated under GB 17733-2008?

GB 17733-2008 regulates geographical name signs for both natural entities (e.g., seas, rivers, mountains) and human entities (e.g., streets, buildings, administrative regions, facilities). It covers all aspects of their production, installation, and use.

Are there any mandatory clauses in GB 17733-2008?

Yes, the standard specifies six mandatory clauses, primarily related to text requirements (use of standard Chinese characters, minority languages, and Pinyin spelling rules) and the electrical safety performance of LED signs. Compliance with these clauses is essential for market access.

How does GB 17733-2008 differ from the previous GB 17733.1-1999?

The updated standard expands the scope to include a wider range of geographical entities. It also introduces new requirements for LED signs, metal-etched signs, and stele-style signs, along with updated testing methods for environmental resistance and luminance.
