ECE Regulation No. 16 sets forth the uniform provisions concerning the approval and installation of seat belts in motor vehicles. This regulation is crucial for ensuring that seat belts are designed, constructed, and installed to provide maximum safety for vehicle occupants. Properly installed seat belts reduce the risk of injury or death in the event of a collision by restraining occupants and preventing them from being thrown around or out of the vehicle.

The regulation specifies the technical standards for the design, construction, and performance of seat belts. These standards ensure that seat belts are strong, durable, and capable of withstanding significant impact forces. The regulation mandates that seat belts must be tested under various conditions to ensure they meet the required safety performance criteria. This includes tests for the belt's tensile strength, durability, and retraction capability.

The regulation also outlines the requirements for the proper installation of seat belts in vehicles. Seat belts must be securely anchored to the vehicle's structure, positioned to provide effective restraint, and easily accessible for use by all occupants. The installation process must ensure that seat belts do not interfere with the operation of other vehicle systems and that they are comfortable and convenient for occupants to use.

The TAT Lab in Iran is authorized to perform testing and certification for compliance with ECE Regulation No. 16. This includes conducting all necessary tests to ensure that seat belts and their installation meet the specified standards for safety, performance, and durability. TAT Lab utilizes advanced testing equipment and methodologies to perform these tests accurately and efficiently. By performing these tests, TAT Lab helps enhance vehicle safety in Iran by ensuring that seat belts are properly designed, constructed, and installed to provide maximum protection for vehicle occupants in the event of a collision.
