Geltungsbereich und Anwendbarkeit

GB 24965.2-2010 applies to yellow flashing warning lights installed on dangerous road sections. It specifies the structure, classification, technical requirements, and testing methods for these traffic safety devices. This standard does not apply to fog lights or temporary safety warning lights, which are covered in other parts of the GB 24965 series. Manufacturers must ensure their products comply with this standard to sell in the Chinese market.

Technische Anforderungen

The standard outlines the structural and classification requirements for yellow flashing warning lights, including components like light sources, control parts, and visors. It categorizes products by their transparent surface size (e.g., ø200mm, ø300mm, ø400mm) and light source type, such as LED or incandescent lamps. Core optical performance requirements are mandatory, including a two-level automatic dimming function for day and night. The standard specifies luminous intensity limits on the geometric axis and a defined light intensity distribution pattern. Additionally, it dictates strict chromaticity requirements to ensure the light remains within a specific yellow coordinate region. Other mandatory clauses cover dynamic visual recognition performance and flashing frequency. The standard sets minimum thresholds for daytime and nighttime dynamic visual recognition distances. The flashing frequency must fall within a defined range, and the light-to-dark time ratio must be equal. Products failing to meet these mandatory optical, visual, and flashing parameters will be considered non-compliant.

Prüfverfahren

Testing procedures involve optical performance evaluations in a standard darkroom to measure luminous intensity and chromaticity coordinates, often referencing GB 4599-2007. Dynamic visual recognition is tested under specific vehicle speeds and weather conditions. Flashing frequency is verified using frequency meters and oscilloscopes. Other tests, such as sealing and environmental adaptability, refer to the methods outlined in GB/T 24965.1-2010.

Häufige Fragen

Which clauses in GB 24965.2-2010 are mandatory?

The clauses regarding optical performance (5.4), dynamic visual recognition performance (5.5), and flashing frequency (5.6) are mandatory. All other clauses are recommended.

What products are regulated under GB 24965.2-2010?

It applies specifically to yellow flashing warning lights installed on dangerous road sections. It does not cover fog lights or temporary safety warning lights.

Does this standard reference other standards?

Yes, it extensively references GB/T 24965.1-2010 for general requirements, GB 14887-2003 for road traffic signal lights, and GB 4599-2007 for testing conditions.
