ATD Aluminum Honeycomb Energy Absorber

Neck Certification

ATD’s or crash test dummies are used worldwide for the evaluation of automotive safety restraint systems in crash testing. The dummies are regulated test devices per the Hybrid Ill in the USA Code of Federal Regulations (Part 572, Subpart E) and also per the European ECE Regulations. Considered to have excellent bio fidelity and instrumentation capability, the ATD or crash test dummy can also be used in many non-automotive applications such as wheelchairs, medical and sport equipment.

To ensure certified performance, ATD’s certification requires neck extension/flexion tests. Aluminum Honeycomb energy absorbers are used to create the pulse for neck flexion extension tests.
