ECE Regulation No. 11 sets forth the uniform provisions concerning the approval of vehicles with regard to their door latches and door retention components. This regulation is crucial in ensuring that the doors of vehicles remain securely closed during normal driving conditions as well as in the event of a collision, thus enhancing the overall safety of the occupants.

The regulation specifies various technical requirements for the construction, installation, and performance of door latches and door retention components. These components must be able to withstand specific forces and remain functional under different environmental conditions. The aim is to prevent accidental door openings that could lead to passengers being ejected from the vehicle or injured by the door itself.

Testing procedures are clearly defined within the regulation to ensure compliance. These include static and dynamic tests that simulate real-world conditions. Manufacturers must 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 over the vehicle's lifetime.

ECE Regulation No. 11 is part of a broader framework of safety standards developed by the UNECE (United Nations Economic Commission for Europe) to promote vehicle safety across member countries. By adhering to this regulation, manufacturers contribute to reducing the risk of injuries and fatalities resulting from door-related incidents, thus promoting safer road travel for all users.
