新版《汽车侧面碰撞的乘员保护》国标发布，“新”在哪里？

Core Viewpoint - The newly released national standard for "Passenger Protection in Side Collisions" aims to significantly enhance the safety of vehicle occupants during side impact accidents, reflecting advancements in vehicle design and materials since the previous standard was established in 2006 [1][2][3]. Group 1: New Standard Implementation - The new standard will be mandatory and is set to take effect on July 1, 2026, marking a significant regulatory update in vehicle safety standards [3]. - The standard introduces a comprehensive safety system that spans from collision protection to accident rescue, indicating a holistic approach to vehicle safety [2]. Group 2: Technical Upgrades - The new standard includes stricter assessment criteria and evaluation systems, which necessitate upgrades to core testing equipment used in collision experiments, such as the mobile deformable barrier, which has increased in weight from 950 kg to 1400 kg to better simulate average vehicle characteristics [4][5]. - Enhanced requirements for the mobile deformable barrier's performance and structure have been established to more accurately reflect modern vehicle designs [5]. Group 3: Enhanced Safety Measures - The new standard mandates the use of advanced crash test dummies equipped with sensors to capture critical data on the impact experienced by occupants, focusing on areas most susceptible to injury, such as the ribs and pelvis [5][6]. - Specific requirements for electric vehicles have been introduced, including ensuring that batteries do not shift position during a collision and that they do not catch fire or explode within 30 minutes post-collision [7]. Group 4: Broader Coverage - The scope of the new standard has been expanded to include all passenger cars with fewer than nine seats and light trucks with a maximum design gross weight of less than 3.5 tons, thereby increasing the number of vehicles subject to these safety regulations [5][6]. - China has established a comprehensive passive safety standard system for vehicles, with over 30 existing and upcoming national standards that align closely with international standards, positioning the country as a leader in passive safety measures [8].
