Scope of Application: Applicable to interior rearview mirrors, exterior rearview mirrors (main, wide-angle, and blind-spot), and permissible Camera-Monitor Systems (CMS) for M1-category (passenger cars) and N1-category (light commercial vehicles) vehicles.
Field of View Requirements: Interior rearview mirrors require a horizontal field of view of ≥20° and a vertical field of view of ≥8°; exterior rearview mirrors must ensure lateral coverage of at least 2.5 meters to the rear-side (at a specific distance from the vehicle's rear), with no significant distortion and blind-spot obstruction limited to ≤15%.
Reflectivity Specifications: Interior rearview mirror reflectivity ≥80%; main exterior rearview mirror reflectivity typically 40%–80%; convex wide-angle exterior rearview mirror reflectivity may be as low as ≥4% (balancing anti-glare properties with visibility).
Optical Performance: Mirror surfaces must not exhibit significant color shift, blurring, or distortion; flat mirrors are used for interior rearview mirrors (providing true-to-scale imaging), while convex or dual-curvature mirrors are used for exterior rearview mirrors (expanding the field of view but requiring a warning label stating "objects are closer than they appear").
Mechanical and Environmental Reliability: Must pass tests for vibration, temperature extremes (-30°C to +70°C), damp heat, weather resistance, UV resistance, and mirror surface impact resistance; electric adjustment and heating functions must be stable and reliable.
Electronic Rear-view Mirror Systems (CMS): Included for the first time in GB 15084-2022; requirements include image latency ≤60ms, point light source recognition (e.g., vehicle lights), automatic brightness adjustment, fault redundancy, anti-glare capabilities, and IP-rated protection (e.g., IP67), with no flickering or latency-induced visual discomfort.
Installation and Structural Safety: Secure mounting, absence of sharp edges (pedestrian protection), and clearly defined limits for adjustment mechanisms; exterior mirrors must not cause additional injury during a collision (e.g., breakaway design).
Certification Requirements: As a safety-critical component, it must obtain CCC certification (if listed in the mandatory certification catalog) and comply with the GB 15084-2022 standards during vehicle type-approval testing.
