Обзор требований
Этот обзор пока доступен только на английском языке.
Область применения
This standard specifies the technical requirements, test methods, and same-type approval criteria for the roof crush resistance of passenger cars. It is applicable to M1 category vehicles and is explicitly not applicable to convertibles. Manufacturers of M1 vehicles must comply with this standard to obtain type approval in China. The standard replaces the previous GB 26134-2010 edition.
Технические требования
The standard outlines the structural integrity requirements for vehicle roofs under static loading conditions. For vehicles with symmetrical body structures, the load is applied to a randomly selected side; for asymmetrical structures, the weaker side is tested. The applied load is specified as 3.0 times the vehicle's kerb mass or 45.0 kN, whichever is smaller. During the test, the displacement of the loading device's lower surface must not exceed 127 mm. Additionally, the standard introduces a new requirement for the resultant force on a headform model, which must not exceed 222 N (with g taken as 9.8 N/kg). This headform force limit is a critical addition in the 2024 revision to enhance occupant protection. The standard also defines specific terms such as sunroof, front windshield trim, raised roof, and altered roof, clarifying their roles in the structural assessment. It includes detailed provisions for same-type approval, considering factors like body structure type, sunroof configuration, and internal dimensions.
Методы испытаний
The testing procedure involves rigidly supporting the vehicle with tires off the ground and adjusting the pitch angle to 0° ± 0.5°. The front outboard seats are adjusted to specific positions, and a three-dimensional H-point device is installed according to GB 11551 to locate the headform model. A rigid rectangular loading plate (1829 mm × 762 mm) is positioned at specific angles (5° forward tilt and 25° outward tilt) relative to the roof. The device applies a downward force at a speed not exceeding 13 mm/s until the required load is reached within 120 seconds. The test measures the loading plate's displacement and the maximum resultant force on the headform model.
Частые вопросы
What products are regulated under GB 26134-2024?
GB 26134-2024 regulates the roof crush resistance of M1 category passenger cars. It does not apply to convertibles.
Are there any updates from the previous version of GB 26134?
Yes, the 2024 version replaces GB 26134-2010. Key updates include the addition of the headform force limit (222 N), changes to the applied load limit, new requirements for vehicle pitch angle during testing, and the addition of same-type approval criteria.
When does GB 26134-2024 take effect?
For new type approvals, the standard is effective from its implementation date (2025-07-01). For previously approved models, it becomes mandatory 25 months after the implementation date.
