ECE Regulation No. 58 sets forth the uniform provisions concerning the approval of rear underrun protective devices (RUPDs) and the rear underrun protection (RUP) of vehicles. This regulation is crucial for enhancing road safety by ensuring that vehicles, particularly commercial vehicles, are equipped with devices that prevent smaller vehicles from sliding under the rear of a larger vehicle in the event of a collision. This helps to reduce the risk of severe injuries or fatalities.

The regulation specifies the technical standards for the design, construction, and performance of rear underrun protective devices. These standards ensure that RUPDs are robust enough to withstand significant impact forces, thereby providing effective protection. The regulation mandates that these devices must be tested under various conditions to ensure they meet the required safety performance criteria.

Testing procedures are rigorously defined to ensure compliance with the regulation. These tests include static and dynamic tests that simulate real-world collision scenarios. Manufacturers must conduct these tests to demonstrate that their RUPDs meet the required standards. The regulation also includes provisions for the durability and reliability of these devices to ensure they function correctly over the vehicle’s lifetime.

The TAT Lab in Iran is authorized to perform testing and certification for compliance with ECE Regulation No. 58. This includes conducting all necessary tests to ensure that rear underrun protective devices meet the specified standards for safety, performance, and durability. TAT Lab uses advanced testing equipment and methodologies to perform these tests accurately and efficiently. By performing these tests, TAT Lab helps enhance road safety in Iran by ensuring that commercial vehicles are equipped with RUPDs that provide effective protection in the event of a rear-end collision.
