Impact energy attenuation
How the helmet manages an impact.
A technician positions the helmet on the impact-test equipment. This method examines how the helmet construction manages impact energy under controlled test conditions.

A closer look at how
helmets are evaluated.
Helmet testing is not a single moment. It is a sequence of controlled procedures, each focused on a different part of performance.
These films show impact, conditioning, retention and stability equipment in use.
Inside the test lab
Four methods.
Four different questions.
Each setup focuses on a specific part of the helmet, so parents can understand what the test is designed to examine.
Environmental conditioning
Prepare the sample for what comes next.
The helmet is placed in a water-conditioning chamber before further evaluation.
Dynamic strength of retention
Examine the restraint system under load.
The retention system is mounted on a rig for testing under a controlled dynamic load.
Positional stability
Check whether the helmet stays in position.
The fitted helmet is placed on a stability rig. The method examines whether it remains correctly positioned when a defined force is applied.
What to look for
Safety is more than a single test.
Impact is only one part.
Conditioning, retention strength and positional stability each examine a different part of helmet performance.
Fit still matters.
A helmet must be selected and adjusted for the individual rider. Use the size and fit guidance on the product page.
Check the exact product.
Current specifications and applicable certification information belong to the specific helmet you are considering.
