A Day in the Life: Low-impact testing

by Andrew Redman April 20, 2018

Ever wondered how our helmets are tested?

 As well as using official testing centres for the European EN1078 safety standards test, we’re also able to run our own tests to answer questions on specific issues.

Our 'Day in The Life' video below presents a snapshot of some of the testing that we perform on the Hedkayse helmets to ensure they’re tough enough! 


To test how the Hedkayse One helmet responds to the drops and knocks expected in everyday life, we dropped two beta helmets from a height of 31cm. We also put a traditional expanded polystyrene (EPS) helmet through these drops for comparison.

The units we use to assess the performace of the helmet is g - the unit that represents acceleration due to gravity. When testing helmets this acceleration is technically negative, as it is a measure of how much the helmet is decelerating - how much time it takes to stop. The lower the deceleration, the less force is transferred into the wearer of the helmet.

The helmets received 5 drops each, 10 minutes apart. You can see the results in the table below:

Hit Deceleration (g)
 EPS Helmet Hedkayse Helmet (1) Hedkayse Helmet (2)
1 33.93 40.57 40.21
2 57.81 46.24 41.28
3 65.11 38.56 44.23
4 68.69 41.66 36.76
5 67.64 39.20 41.92

It’s clear that the performance of the EPS degraded over time, and after only 3 of our low hits, we even began to notice some compression of the polystyrene, leading to a flexing of the outer shell. 
In contrast, the Hedkayse helmets barely increased at all over their series of hits.

We’re confident that, unlike a traditional EPS helmet, the Hedkayse helmet is able to stand up to the knocks and bumps of everyday life.
