ECE 22.06 Explained: What Helmet Certification Actually Means

For a full sizing guide across our range, visit acquiremag.com.

A helmet that is the right size should feel snug all the way round with no single pressure point, and it should not shift when you turn your head firmly from side to side. A helmet that moves independently of your head on a shake test is not the right fit, regardless of what the size label says.

Once the shell is formed and cured, it moves through finishing: sanding, painting or leather trimming, and fitting the internal padding and retention system. Every stage is checked before the next begins, since a fault caught early is far cheaper to fix than one found at the end.

Any impact, including a helmet dropped from a moderate height, can compress the inner liner in ways that are not visible from outside. A helmet is designed to absorb one significant impact by sacrificing that inner material, so a helmet involved in a crash should always be replaced, not inspected and reused.

ECE 22.06 is the current European standard that motorcycle helmets are tested against, and it replaced the older ECE 22.05 standard with a wider and more demanding set of tests. Helmets are checked for impact absorption at multiple points on the shell, not just the crown, and the standard also tests rotational forces, which earlier standards largely ignored.
