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
GB 811-2022 is a mandatory national standard that applies to safety helmets worn by drivers and passengers of motorcycles and electric bicycles. It categorizes helmets into Class A (for motorcycles and e-bikes) and Class B (exclusively for e-bikes), further divided by shape into full-face, 3/4, and 1/2 helmets. This standard does not apply to bicycle, skateboard, or roller skate helmets, nor does it cover professional industrial safety helmets. Manufacturers exporting these vehicles or accessories to the Chinese market must ensure compliance.
Technical requirements
The standard rigorously defines the structural and performance criteria for helmets. Structurally, it mandates specific configurations for the shell, protective padding, comfort padding, retention system, and goggles based on the helmet class and type. The shell must feature streamlined designs, specific reflective material areas, and strict limits on internal and external protrusions to prevent secondary injuries. Manufacturers must ensure the retention system is highly robust and features quick-release mechanisms that prevent accidental opening. Performance requirements are comprehensive, covering critical safety aspects. The standard sets strict limits on mass based on helmet type to reduce neck fatigue. It defines minimum field of vision angles to ensure operational safety. For goggles, it specifies requirements for impact strength, minimum luminous transmittance (visible light transmission), and newly introduced abrasion resistance with specific haze limits. The core protective capabilities are heavily regulated through collision energy absorption and penetration resistance criteria. Helmets must pass impact tests where peak acceleration and impact duration are strictly limited to protect the wearer's head. Additionally, the standard introduces novel assessments for shear force of surface protrusions and surface friction, ensuring the helmet exterior does not snag on asphalt during an accident. Helmets must also pass stiffness and retention system stability tests to ensure structural integrity under dynamic loads.
Testing methods
GB 811-2022 outlines specific testing procedures using standardized metal headforms (sizes A, E, J, M, O). Key tests include the collision energy absorption test (dropping a helmet-equipped headform onto flat and hemispherical anvils), penetration resistance test (dropping a steel cone), and retention system strength test (applying dynamic loads to the chin strap). New procedures include the shear force test (sliding a weighted carriage with a blade over the helmet) and surface friction test (using an abrasive carriage). Tests are conducted under various environmental pre-conditioning, including high temperature, low temperature, and water immersion.
FAQs
What products are regulated under GB 811-2022?
GB 811-2022 applies to helmets for motorcycle and electric bicycle users. It classifies helmets into Class A (for motorcycle and e-bike users) and Class B (exclusively for e-bike users). It does not apply to bicycle, skateboard, or roller skate helmets, nor professional safety helmets.
Are there any updates from the previous version of GB 811?
The 2022 version expands the scope to include electric bicycle helmets, introduces new testing for shear force of protrusions, surface friction, and goggle abrasion resistance. It also updates headform dimensions and adds specific helmet category identification marks.
How does GB 811-2022 differ from international helmet standards?
While both aim to reduce head injuries, GB 811-2022 is a mandatory Chinese national standard with specific classifications (A/B classes and 1/2/3 types) tailored to local vehicle regulations. It includes unique testing procedures, such as specific stiffness and shear force tests, which may differ from general ISO or ECE standards.
