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 M and N category motor vehicles, as well as L category vehicles with at least a partially enclosed driver's cab. It covers the technical requirements, test methods, and installation criteria for indirect vision devices, including traditional mirrors and Camera-Monitor Systems (CMS). It is mandatory for manufacturers designing visibility systems for the Chinese automotive market.
Technical requirements
The standard classifies indirect vision devices into seven classes (I to VII) based on their provided field of vision, such as interior, main exterior, wide-angle, and front-view. For traditional mirrors, it specifies general dimensional limits, edge radius requirements to minimize pedestrian injury, and strict reflectance and curvature radius tolerances to prevent image distortion. For Camera-Monitor Systems (CMS), the standard outlines extensive functional requirements. It mandates criteria for luminance adjustment, directional and lateral uniformity, contrast reproduction, and color fidelity. CMS must also meet strict performance metrics for sharpness, geometric distortion, frame rate, and system latency. Installation requirements dictate the minimum number of devices required per vehicle type, positioning constraints to ensure adequate field of vision, and specific mounting heights. For CMS, it further specifies default and adjustable fields of view, overlay display limits, and electronic system safety protocols to warn drivers of failures.
Testing methods
The standard mandates an impact test using a pendulum and rigid sphere to ensure mirrors and CMS cameras do not shatter or cause excessive protrusion upon collision. It also specifies a bending test for protective housings. For CMS, it references ISO 16505 and ISO 9241-305 for evaluating luminance, contrast, flicker, and point light source detection. Appendices provide detailed procedures for reflectivity measurement, curvature radius calculation, and critical object detection distance determination.
FAQs
What products and vehicles are regulated under GB 15084-2022?
GB 15084-2022 applies to M and N category vehicles, as well as L category vehicles with at least a partially enclosed cab. It regulates both traditional mirrors and Camera-Monitor Systems (CMS).
What are the main updates in GB 15084-2022 compared to the 2013 version?
The 2022 version introduces comprehensive technical and installation requirements for Camera-Monitor Systems (CMS), updates terminology such as critical object and detection distance, and modifies the minimum installation quantities and field of vision requirements for various device classes.
Does GB 15084-2022 align with international standards like ISO?
Yes, the standard references several international standards for CMS testing, including ISO 16505 for ergonomic and performance aspects, ISO 15008 for in-vehicle visual presentation, and ISO 9241-305 for electronic visual display test methods.
