FMVSS 216 Roof Crush NVH Testing
The Federal Motor Vehicle Safety Standard (FMVSS) 216 specifies requirements for roof crush resistance in passenger cars, sport utility vehicles, and vans manufactured after September 1, 1971. The purpose of this standard is to ensure that the structural integrity of a vehicle's roof can withstand significant forces without collapsing during an accident. Roof crush testing under FMVSS 216 is crucial for ensuring safety compliance in the automotive industry.
The test involves applying a specified load vertically to the roof using hydraulic equipment until failure occurs or up to a maximum load of 5,000 pounds (approximately 22 kN). The specimen preparation includes mounting the vehicle's roof on a rigid frame with specific boundary conditions. The loading is applied at a rate that simulates real-world crash scenarios.
The testing procedure must adhere strictly to FMVSS 216 requirements, which dictate precise load application rates and environmental controls for temperature and humidity. The test apparatus typically includes hydraulic presses capable of applying the required forces accurately while measuring deflection and stress distribution in real-time. Post-test inspections involve examining the roof structure's integrity and assessing any deformation or damage.
The FMVSS 216 test results are critical for ensuring that vehicles meet safety standards and can be trusted by consumers. Compliance with this standard is mandatory, and non-compliance could result in significant financial penalties and reputational damage for manufacturers.

Scope and Methodology
The scope of FMVSS 216 Roof Crush NVH Testing encompasses the structural integrity testing of vehicle roofs under specified loading conditions. The methodology involves mounting a representative section of the roof on a rigid frame, applying a vertical load to simulate real-world crash scenarios, and monitoring deformation and stress distribution throughout the test.
The testing process begins with specimen preparation, which includes ensuring that the roof is free from any defects or imperfections that could affect the outcome of the test. The boundary conditions are carefully set up to ensure accurate loading and measurement.
- Specimen Preparation: Ensuring the roof section is clean, free of cracks, and undamaged before testing.
- Loading Equipment: Utilizing hydraulic presses capable of applying loads up to 5,000 pounds (approximately 22 kN).
- Data Acquisition: Continuous monitoring of deflection, stress, and strain using high-precision sensors.
The loading rate is critical in simulating real-world conditions accurately. Our laboratory uses advanced software to control the loading rate and ensure it adheres strictly to FMVSS 216 specifications. Post-test inspections involve a comprehensive examination of the roof structure for any signs of failure or damage. Any deviations from expected results are documented, providing valuable insights into potential areas for improvement.
The testing environment is controlled to maintain consistent temperature and humidity levels, ensuring that test conditions are as close to real-world scenarios as possible. This attention to detail ensures accurate and reliable test results.
