The Cabin Strength Test for Commercial Vehicles (ECE R29) is a specialized assessment designed to evaluate the structural integrity and safety of the vehicle cabin under critical crash conditions. In this test, the cabin is subjected to simulated high-impact forces and pressures to assess its strength and stability.

The importance of this test lies in its critical role in protecting occupants and enhancing road safety. It helps prevent dangerous cabin deformations during accidents and is recognized globally as a mandatory standard for heavy vehicle manufacturers.

The results of this test indicate the cabin’s resistance to crashes, its ability to maintain a safe survival space for occupants, and the structural stability under critical conditions. These results serve as the basis for issuing internationally recognized safety certifications for heavy vehicles.

As the only authorized and accredited center in Iran, TAT Laboratory conducts this specialized test using the most advanced equipment available internationally. By issuing internationally recognized safety certificates, the laboratory significantly supports domestic manufacturers in improving the safety standards of their products and plays a key role in enhancing the quality of Iranian heavy vehicles. Conducting this test is considered a vital step toward ensuring the safety of heavy vehicles and reducing road fatalities.
