ECE Regulation No. 11 establishes uniform provisions for the approval of vehicles with regard to door locks and door retention components. This regulation is crucial for ensuring that vehicle doors remain securely closed during normal driving conditions as well as in the event of a collision, thereby enhancing the overall safety of occupants.

This regulation specifies various technical requirements for the construction, installation, and performance of door locks and door retention components. These components must be capable of withstanding specific forces and must continue to function under different environmental conditions. The objective is to prevent accidental door opening, which could result in occupants being ejected from the vehicle or injured by the door itself.

The test procedures are clearly defined in this regulation to ensure compliance. These include both static and dynamic tests that simulate real-world conditions. Manufacturers are required to conduct these tests to demonstrate that their vehicles meet the required standards. The regulation also includes provisions for the maintenance and inspection of these components to ensure continued compliance throughout the vehicle's service life.

ECE Regulation No. 11 is part of a broader framework of safety standards developed by the United Nations Economic Commission for Europe (UNECE) to promote vehicle safety across member countries. By complying with this regulation, manufacturers help reduce the risk of injury and fatalities associated with door-related incidents, thereby contributing to safer road travel for all users.
