What is certimoov ?

Project description

Certimoov is a test protocol drawn up by scientists to objectively test the protection capacity of equipment. 
As of today, Certimoov starts with tests on motorbike and cycling helmets. A new method was created for this purpose to evaluate helmets under the most realistic conditions possible by taking into account new kinds of impact and advanced  brain injury criteria. The result is shown on this website in the form of a point scale out of 5 for each helmet.

History of certimoov

Why is there a new test method in addition to the existing regulation?

To complete and reinforce current regulations

European regulations test helmets in straight-line impact, in other words perpendicular to the surface the impact takes place on. Furthermore, the criteria for accepting a helmet is based on the translation acceleration registered with a rigid headform which does not faithfully represent the human brain. Moreover,, the acceptance criterion for the regulation is either yes or no: either the helmet is accepted under the regulation or it isn’t.  
Certimoov recreates more realistic impacts (oblique impacts) and integrates the new brain model to measure the effect of a collision on the brain. The Certimoov tests are, more realistic and they enable a precise estimation of the risk of brain injury and classify helmets according to the level of safety, by a points system from 0 to 5.

Advances in biotechnology

Certimoov uses advances to improve its test method. The test bank enables the reproduction of more realistic impacts (for example, in the angle and speed) and a new digital model of the head is used. This model makes it possible to calculate the mechanical response of the brain and enables bioengineers to assess the brain injury risk for each impact.

Encouraging the evolution
of thought

Certimoov’s goal is to inform users and also manufacturers and the authorities about the level of protection afforded by equipment. Thanks to these complete tests, users can employ the criteria of safety in their choice of helmet with clearer and more detailed results than those in the current regulations. Manufacturers can use Certimoov tests to improve the safety level of their helmets even further and can contact Certimoov if they wish to obtain more details about the test method and its results. They can also contact the University of Strasbourg if they wish to evaluate prototypes. The methodology can be included in the internal development of their product.

Understanding the points system

Detailed explanation
of points

In total 6 types of impact are tested: 3 perpendicular impacts and 3 oblique  impacts. Each impact is repeated 3 times, requiring a total of 6 helmets to obtain a final mark. Each impact produces 6 curves which show linear and rotational acceleration versus time.

The details of the notes

Calculating the overall mark

The overall mark is the average of 6 different marks. You can see it on the “helmet cards”. It enables the classification of the helmets from the best to the least positive mark. Five stars are given to the helmet with the best results in the tests, while 0 points denotes the least safe helmet according to the Certimoov method.

These curves are then included in the mechanical modelling of the brain, which lets the bioengineers estimate the risk of injury for each impact and come up with a mark from 0 to 5.

Points to be taken into account

Points of impact tested

The points of impact tested are frontal, lateral and occipital. They represent different kinds of impact which could take place in traffic accidents.

Limitations on jet helmets

NB: Jet helmets might score more points than full-face helmets on this website. This is because Certimoov tests the impact of a collision on the brain and not on the face.
