Applicability depends on product scope, certification route, competent authority notices and transition rules. Requst for the translation or verify source before using this record in a compliance decision.
Compliance overview
Scope and applicability
This standard applies to the design, production, inspection, and installation of retro-reflective devices and markings used on motor vehicles. It covers four main product categories: retro-reflectors, retro-reflective markings (both sheeting and reflector types), rear marking plates, and warning triangles. It is mandatory for manufacturers producing visibility-enhancing safety components for the Chinese automotive market. The standard also specifies the equipment and installation requirements for these devices on various vehicle types, including trucks, trailers, and slow-moving vehicles.
Technical requirements
The standard specifies comprehensive physical and optical requirements for vehicle reflective devices. For general requirements, it mandates strict criteria for appearance, shape, dimensions, and color (both day and night chromaticity). It defines specific photometric performance limits, including the coefficient of luminous intensity for reflectors and warning triangles, and the coefficient of retro-reflection for retro-reflective sheeting and marking plates. Manufacturers must ensure uniform luminance across the reflective surfaces without obvious dark spots. Environmental durability and material robustness are heavily emphasized. The devices must withstand rigorous testing conditions, demonstrating resistance to water, solvents (fuel and lubricants), extreme temperatures, salt spray corrosion, and impact. For instance, retro-reflective sheeting must maintain structural integrity and adhesion performance (with specific peel strength requirements) after exposure to harsh elements. Materials must not exhibit cracking, peeling, or significant photometric degradation after environmental exposure. The standard also details specific structural and functional requirements tailored to each device type. Warning triangles must possess structural stability, wind resistance, and shape visibility. Rear marking plates are categorized for slow-moving, heavy, and long vehicles, with specific material compositions (e.g., fluorescent materials combined with retro-reflective sheeting) and robustness criteria. Additionally, it provides extensive guidelines on the installation and layout of these markings on vehicles, ensuring proper contour outlining and visibility for specific vehicle categories like tank trucks and flatbed trailers.
Testing methods
The standard outlines a series of rigorous evaluation procedures to verify compliance. Photometric testing is conducted using specialized equipment to measure luminous intensity and retro-reflective coefficients at various observation and illumination angles. Colorimetric testing evaluates both daytime and nighttime color coordinates under standard illuminants. Environmental tests include water immersion, solvent exposure (using n-heptane and toluene mixtures), high/low-temperature chamber exposure, and salt spray corrosion testing. Additionally, mechanical tests such as impact resistance (using steel ball drop methods), bending, and high-pressure washing are specified to verify the physical durability of the materials and devices.
FAQs
What products are regulated under GB 11564-2024?
This standard regulates retro-reflective devices and markings for motor vehicles, including retro-reflectors, retro-reflective markings (both sheeting and reflector types), rear marking plates, and warning triangles.
Are there any updates from the previous version of GB 11564?
The 2024 version is a significant consolidation that replaces four previous standards (GB 11564-2008, GB 19151-2003, GB 23254-2009, and GB 25990-2010). It introduces new requirements for reflector-type markings, updates photometric and colorimetric performance criteria, and adds post-test photometric re-evaluations for several environmental tests.
When does GB 11564-2024 take effect for new vehicle models?
For new type approvals of devices, the standard is effective from July 1, 2025. For new vehicle type approvals, it applies from the 13th month after implementation. Existing approved vehicle types and devices must comply by the 37th month.
