적용 범위

GB 11566-2024 establishes the mandatory requirements and test methods for external projections on M1 category vehicles (passenger cars). It specifically applies to vehicle exterior parts located no higher than 2 meters from the ground, no lower than the floor line, and accessible by a 100mm diameter sphere. This standard excludes external indirect vision devices and traction (towing) equipment.

기술 요구 사항

This standard mandates that vehicle exterior surfaces must not feature any sharp outward-facing parts that could increase the risk of injury to pedestrians or cyclists during a collision. General requirements stipulate a minimum radius of curvature of 2.5mm for protruding parts, though exceptions apply for specific materials with a hardness not exceeding Shore 60HA. The standard details specific criteria for components such as decorative trims, headlights, and grilles, requiring certain parts to retract, detach, or deform safely when subjected to specific external forces.\n\nSpecial requirements are outlined for critical exterior elements. For windshield wipers, protective covers must meet specific area and radius criteria. Bumpers and their covers must be designed to reduce scratching risks, with specific curvature rules for rigid surfaces. Door handles, hinges, and front hood edges are restricted in their maximum protrusion heights, and rotating handles must feature return mechanisms or protective casings to prevent snagging.\n\nThe standard also regulates wheels, metal panel edges, and luggage racks, ensuring no sharp protrusions extend beyond the wheel rim or vehicle's outermost edge. Antennas must adhere to strict positioning and height limits, often requiring flexible bases or breaking away safely under force to prevent injury. New to this revision are the requirements for surveillance cameras and monitoring mirrors, which must not protrude more than 50mm beyond the vehicle's extreme outer edge.

시험 방법

The standard outlines geometric and physical testing methods to verify compliance. Measurements involve using a 100mm diameter sphere to determine the nominal line of a panel and measure the projection height of parts. A 30-degree half-angle cone is used to establish the vehicle's floor line. Additionally, force application tests using a flat-end pressure head (up to 50mm in diameter) are specified to evaluate the retraction, detachment, or deformation behavior of components like decorative parts and antenna bases under loads of 100N or 500N.

자주 묻는 질문

What products are regulated under GB 11566-2024?

GB 11566-2024 applies to M1 category vehicles (passenger cars) as defined in GB/T 15089. It regulates the design and external projections of vehicle components like bumpers, grilles, door handles, and antennas to minimize pedestrian injury. It does not apply to indirect vision devices or towing devices.

Are there any major updates in GB 11566-2024 compared to the 2009 version?

The 2024 revision introduces new definitions for front hood, bumper covers, and surveillance cameras/mirrors. It updates requirements for windshield wipers, adds specific technical requirements for bumper covers and surveillance devices, and includes new chapters on same-type approval judgment and standard implementation timelines.

How does GB 11566-2024 test for external projection compliance?

The standard uses specific geometric measurement methods, such as rolling a 100mm diameter sphere along the vehicle's exterior surface to determine contact points and projection heights. It also uses a 30-degree half-angle cone to establish the floor line and applies specific force tests (e.g., 100N or 500N) using a flat-end pressure tool to assess the collapse or bending behavior of decorative parts and antennas.
