EN 14572 Pedestrian Impact Headform Crash Testing
The EN 14572 standard specifies the method of testing the impact resistance and deformation behavior of vehicle fronts in pedestrian accidents. This test is crucial for ensuring that vehicles are designed to mitigate the severity of injuries caused by impacts with pedestrians. The headform used in this crash testing simulates an adult male's head, providing a standardized approach to assessing potential damage to human skulls during collisions.
The procedure involves placing a specified mass and shape headform on the vehicle’s bonnet (hood) or windscreen at a predetermined speed. The impact is then analyzed for deformation, displacement, and other factors that indicate how much force could be exerted on an actual pedestrian. Compliance with EN 14572 helps manufacturers meet regulatory requirements in Europe and ensures their vehicles are safe and protective.
The test setup typically includes a crash sled, which is equipped to deliver the specified impact velocity onto the vehicle’s front. Sensors within the headform measure its acceleration during the impact. Post-impact analysis focuses on the deformation of the headform as well as the force distribution along the bonnet and windshield.
Failure criteria under EN 14572 are based on both structural integrity and human safety considerations. Structural failure is defined by specific deformation thresholds, while safety considerations involve ensuring that no part of the headform exceeds a certain acceleration limit during impact. Compliance with these standards not only ensures regulatory compliance but also enhances brand reputation by demonstrating a commitment to pedestrian safety.
The EN 14572 standard has been pivotal in reducing pedestrian injury rates and is widely adopted across the automotive industry. By adhering to this standard, manufacturers can ensure that their vehicles are designed with pedestrian safety at the forefront, contributing significantly to road safety initiatives globally.

Quality and Reliability Assurance
The EN 14572 test is integral to the quality assurance process in automotive manufacturing. By incorporating this test into their development pipelines, manufacturers can identify design flaws early on that might lead to pedestrian injury during accidents. This proactive approach not only enhances product reliability but also reduces potential recalls and liability issues.
Compliance with EN 14572 ensures that all vehicles undergo rigorous testing before being released to the market. This standardization process helps in maintaining consistent quality across different models and batches, ensuring uniform performance and safety standards.
The detailed analysis provided by this test also aids in continuous improvement efforts within R&D departments. Engineers can use the insights gained from these tests to refine materials, design strategies, and overall vehicle structures aimed at enhancing pedestrian protection. This iterative process ensures that each new model iteration is safer than its predecessors.
In summary, EN 14572 plays a vital role in the quality assurance framework by providing a clear set of guidelines for testing and evaluation. It serves as an essential tool for manufacturers to ensure their products meet stringent safety standards before reaching consumers.
