事关汽车门把手安全，强制性国家标准发布

Core Viewpoint - The mandatory national standard for automotive door handle safety, titled "Technical Requirements for Automotive Door Handles" (GB 48001-2026), will be implemented starting January 1, 2027, to enhance vehicle safety in response to advancements in electrification technology [2][3]. Summary by Sections Standard Overview - The standard was approved by the National Market Supervision Administration and the National Standardization Management Committee on January 28, 2026, and aims to regulate the design of automotive door handles to improve safety [2]. Background of Development - The development of this standard is driven by the evolution of electric vehicle technology and the need for enhanced safety features in critical components like door handles [3]. Development Process - The standard's formulation involved collaboration among over 40 domestic vehicle manufacturers, parts suppliers, and testing organizations, with multiple rounds of discussions among industry experts to finalize the draft [4]. Scope of the Standard - The standard applies to M1 and N1 class vehicles and multipurpose trucks, with provisions for other vehicle types to follow suit [8]. Safety Requirements for Exterior Door Handles - Each vehicle door (excluding the tailgate) must be equipped with a mechanical release for the exterior door handle, ensuring it can be opened in emergencies, such as after an irreversible constraint or thermal runaway of the battery [11]. - The exterior door handle must be located within a specified shadow area to ensure accessibility [13]. - The design must allow for sufficient hand operation space to facilitate the mechanical release function [15]. Technical Requirements for Exterior Door Handles - The exterior door handle must withstand a force of at least 500N without breaking or detaching, and it should allow the door to be opened without tools after testing [19]. Safety Requirements for Interior Door Handles - Each vehicle door must have at least one mechanical release interior door handle that can independently open the corresponding door [20]. - The installation location of the interior door handle must be visible and accessible, with specific distance requirements from the door edge [20]. Marking and Instruction Requirements for Interior Door Handles - Interior door handles must have permanent markings that are easily identifiable and visible in low-light conditions, along with clear operational instructions nearby [21]. Technical Requirements for Interior Door Handles - Similar to exterior handles, the interior door handles must also be tested to ensure they can be operated without tools [22].
