On January 30, 2024, MIIT (Ministry of Industry and Information Technology) issued a notification seeking opinions on the following two mandatory national standards, with a deadline for comments set on March 30, 2024:

1.      The Requirements of Safety in the Event of Rear-End Collision for Passenger Cars (Draft for Comments)

This standard is the revision of its 2006 version, aiming to upgrade and enhance safety requirements for rear-end collisions in automobiles. The objective is to establish a more scientifically-based assessment framework with improved metrics. This adaptation addresses the evolving demands for safety performance in fuel and electrical systems during rear-end collisions, ultimately reducing the risk of post-collision fire incidents.

The standard outlines technical requirements and testing methods for passenger car rear-end collision safety, applicable to M1-class vehicles. While referencing UN Regulation NO.34, several modifications have been made, including:

l  Test speed: The standard specifies a test speed of (50±2) km/h, as opposed to the "35～38 km/h" specified in UN Regulation NO.34.

l  Mass of the moving vehicle and collision device: The standard sets it at 1400 kg±20 kg, whereas UN Regulation NO.34 specifies 1100 kg±20 kg.

l  Crash test dummy: The standard places a Hybrid III 50th percentile dummy in the driver's position, restrained by a seatbelt, unlike UN Regulation NO.34, which does not require the placement of a dummy.

l  Pendulum test: The standard eliminates the pendulum test, while UN Regulation NO.34 allows for its use.

2.      The Protection of the Occupants in the Event of a Lateral Collision (Draft for Comments)

This standard is the revision of its 2006 version, with the goal of upgrading technical requirements for occupant protection in the event of a side collision. It aims to establish a more scientifically-based assessment framework, enhance vehicle side-impact performance, and reduce injuries to occupants in traffic accidents.

The standard specifies technical requirements and testing methods for occupant protection in the event of a lateral collision, applicable to M1-class and N1-class vehicles, as well as multi-purpose trucks. While referencing UN Regulation NO.95, modifications have been made, including:

l  Applicability: The standard applies to M1-class and N1-class vehicles, as well as multi-purpose trucks, while UN Regulation NO.95 is applicable to M1 and N1 vehicles with a maximum allowable total mass less than 3500 kg, and M1-class vehicles with a maximum allowable total mass greater than 3500 kg when the lowest seat point is no more than 700 mm from the ground.

l  Mass of the mobile test device: The standard sets it at 1400 kg±20 kg, while UN Regulation NO.95 specifies 950 kg±20 kg.

l  Type of honeycomb aluminum barrier: The standard adopts the AE-MDB V3.9 honeycomb aluminum barrier, in contrast to the EEVC 2000 honeycomb aluminum barrier used in UN Regulation NO.95.

l  Use of crash test dummies: The standard places a WorldSID 50th percentile dummy or ES2-re dummy in the front seat for side impacts, while UN Regulation NO.95 places an ES2 dummy in the same scenario.
