A 2 Minute Guide to ECE 22.05 (Regulation No.22) for Testing of Crash Helmets

ECE 2205 logo

What is ECE 22.05 (concerning the approval of protective crash helmets)?

The ECE stands for Economic Commission for Europe and the 22 refers to Regulation No.22. The 05 part refers to a specific amendment to the regulation (yawn!). Essentially, they’re rules put in place to make sure crash helmets for sale in Europe protect the head adequately in an accident – and include info. on the tests each helmet must pass to prove they do so. The regs also cover the performance of visors, chin straps and protective chin guards.

ECE 22.05 is the most widely respected and used regulation in the world and is endorsed and used by many countries outside Europe too: as of Nov 2015, that includes most states in Australia.

A quick note on UNECE 22.06

The ECE 22.05 standard is being superceded in 2024 when the new ECE 22.06 regulation comes into force. Till then, you’ll see a mixture of old 22.05 helmets and newer 22.06 on the market. Read more about ECE 22.06 here.

Why do we need Regulation No.22?

The rules are there to make sure if you’re buying a crash helmet to protect you on a motorcycle, then you know the helmet’s giving you at least a minimum level of protection. If there aren’t standards there, manufacturers have a tendency to push out any old tin bowl with a strap on it and claim it’ll save you from headbutting lamp posts, and you won’t have a clue if they’re telling you the truth or not until it’s too late. Regulation 22 tells manufacturers what they have to do in order to produce an effective motorcycle crash helmet and how to prove they’ve complied with the regulations (through testing and labelling). It also gives us buyers/wearers/crashers confidence we’re buying a helmet that offers us at least some protection.

Where can I read about Regulation No. 22?

Funny you should ask. It’s available as a pdf on the UNECE (United Nations Economic Commission for Europe) website. Grab it by clicking this link.

So how do they test the helmets?

They test helmets in a few funky ways under a few even funkier conditions. These include testing for initial impact, rigidity, friction, chin strap strength and  ‘retention’ (making sure the helmet stays in position during impact). But while testing for these, they also subject the lids to various environmental conditions to make sure they carry on protecting wherever we go. That includes subjecting helmets to solvents (!), low and high temperatures, ultraviolet, humidity and moisture. Testing is also supposed to be carried out using the helmet size which is determined to be weakest.

They test the chinstrap to make sure it won’t slip loose, stretch or break under load. They connect the helmet to a test rig that tries to pull the helmet off the head from the back to make sure the chinstrap does its job effectively.

Then they test the visor for scratch and abrasion resistance, refraction, light transmission, opening angle, defects and field of vision. If the manufacturer claims the visor is anti-fog, then they test for that too.

On the helmet itself, they test impact resistance at various points around the helmet including the side, front, rear, crown and chin guard. And they test the reflectiveness of safety stickers too.

And once they’re done testing, they test some more – taking a batch of large and small sized helmets from the first production batch as well as continuously testing throughout the production run.

So you can see, you don’t pass the ECE test easily and unlike the US DOT certification, every helmet has to undergo testing. With DOT, each manufacturer agrees to comply with safety testing but only a selection of lids are chosen to undergo testing to ensure they comply (if they don’t they’re hit with heavy fines).

Helmet labelling

The regs also stipulate what protection each helmet provides and tests/certifies only that protection – such as no chin protection for open faced helmets. It also shows how each helmet and visor should be labelled. For example if a helmet’s approved under regulation 22 it displays a capital E in a circle followed by a number that represents each country (see the pic above). This is followed by a series of other numbers and letters representing specifics of the type approval, approval number and production serial number.

While Regulation 22 ensures motorcycle crash helmets are fit for purpose (and labelled as such) it’s important to realise that this is only one step towards you being able to buy and use a helmet that will protect you in an accident. Crash helmets are always compromised to some extent (what’s effective in a single high speed impact isn’t the same as what’s effective in an impact that has multiple slower speed impacts and includes lots of abrasion for example). It’s also probably true to say that where there’s a helmet testing procedure to be taken (and passed) then a manufacturer’s focus tends to prioritise the passing of the test over other more practical (and effective) ways to protect the rider’s head. But then, that’s one of the drawbacks of imposing any test and arguably a drawback worth risking.

Also, one of the most important factors in reducing head injury is making sure your helmet fits properly (so see our helmet fitting guide).

What about ECE AND DOT Certified Helmets?

Many helmets on sale across the world and are both ECE certified for sale in Europe as well as DOT for the US. But does that mean an ECE helmet’s legal to wear in the states, and vice versa?

It’s a bit of a grey area because if it went to court and you could prove to a judge that they’re identical helmets, you might well be OK.

But the problem lies with the fact that if you got pulled over by the police, they could look at your helmet and expect to see the correct ECE tags and stickers on your helmet. And if it hasn’t got them, that means you’re not wearing a legal helmet.

So you need to wear a helmet with the correct certification and tags relating to the country you’re riding in. Otherwise you could end up with a fine and a confiscated helmet.

P, J & NP labeling and flip-up helmets

When you buy a modular helmet, you probably hope that it’s going to work as a full face helmet when the chin guard’s down. But not all are designed like that – or approved to work as a full face. When they are, they’ll be labelled as both J (open face) and P (protective chin guard) inside the helmet and usually on the label sewn into the chin strap. That’s sometimes called dual homologation.

If it has a chin guard that’s not designed and approved to offer protection, it’ll have the label NP inside.

Finally, SHARP testing supplements the ECE 22.05 testing procedure as they find there’s a wide range in how well crash helmets perform even amongst those which pass Regulation 22, and which is why we focus on helmets that are ECE 22.05 approved and score the highest ratings in the SHARP tests.

    • Hi mate – well as long as it’s a genuine (i.e not fake) helmet, it should have an ece sticker on the rear of the helmet and also a tag inside. After a bit of research, helmets in the Philippines also need an ICC label on the outside of the helmet – so an ICC labelled helmet that’s also ECE and you should be good to go. I don’t know of anywhere you can get a list of ECE approved helmets tbh – but if you look at helmets on sale in reputable European stores, I’d say that’s a good indicator that they’ve been ECE approved.

  1. We sell LS2 HELMETS …. we face few times the helmet is ECER 22.05 test passed but still in a crash the surface of helmet broke , I just want to know when we saw crash test video or some people hitting helmets with hammer not break but in an accident it breaks easily. Most of modular helmet I saw breaks easily in a accident ….. can somebody explain me why it happens ?

    • I guess every accident (and staged youtube video!) is different. If a helmet’s genuine (not a fake) and ECE 22.05 certified, it should be guaranteeing at least a minimum level of protection – which is not to say the shell won’t break under some impacts – whatever the brand.

  2. I have a brand new (still in box ) Suyoka helmet that I bought a few years ago here in Spain. on the strap is shown E9 ECE 22.03.0101 serial number 4076823, trying to find out if this is ok for use in the UK. Thanks for any replies .

    • Thanks for the reply. I asked on a m/bike forum and got Negative replies, I was even told that if another amendment came about that ALL helmets with an 05 would become obsolete !! That would be total rubbish and very costly for you dealers .

      • Interesting. Looking again at your approval number, that should begin 05 (for regulation 22.05) and I just noticed yours starts with 03 (or did you type it wrong?). Sorry if I missed it first time round. How old do you think your helmet is? I believe amendment 05 came in June 2000. Would your helmet be before that? Can’t find any details (yet) of 03 amendment on the UNECE website but they do say there have been several amends since regulation 22 was introduced in 1972. Having said that, even if it was that old I wouldn’t have thought introducing a new series of amendments would make the old illegal (if that’s what they mean by obsolete). Or they may mean dangerous, and they’d probably be right. If it is that old – dude, bin it off and buy a new helmet 🙂

        • It is illegal to sell helmets that pass old regulations but not to use them. Although, if the helmet is that old, the foam inside may have turned solid and it will not dissipate forces as it did before.

          • Kinda. It’ll only be illegal to sell ECE 22.05 helmets in early 2024, so until then it’ll be legal to sell them and wear them – and from Jan 2024 you can still legally wear your old ECE 22.05 helmet anyway as phasing them out isn’t covered by the regulation. Foam does deteriorate of course, but if you bought a new 22.05 helmet at the back end of 2023 for example, it should still be good for many years yet. If you’re concerned about how old your helmet is, the manufacturing date is always stamped inside, usually on a sticker underneath the comfort liner.

  3. For years I had no idea what the various marks meant inside helmets, and thanks to your post you have brought a great deal of clarity.

    Your website is a fabulous resource for riders and the clear impartiality you critique with is welcome.

    Keep up the excellent work!!!!

  4. Sirs I applaud your work in the development of a meaningful standard for motorcycle safety equipment. In particular the reference to the ethnic head shapes and the negatives in designing for specific accident types at the detriment of other protection specifics.

    I now live in Australia and am an active road safety advocate. However, I feel that the powers that be here are intent on developing standards which have additional objectives over and above Road Safety initiatives. I would therefore be greatful of your thoughts on the implementation of a “penetration standard” which to my mind will be gained as a trade off against other positive areas of protection.

    It is my belief that the development of specific standards for the Australian market is a retrograde step with adverse affects. Australia is a multicultural society and as such has a plethora of different ethnic genes. It would therefore be far more appropriate to adopt those standards currently accepted throughout the word as an acceptable standard fircAustealia. This would enable immigrants to select helmets specifically designed for a specific market more suited to themselves.

    My interest is generated as there is currently a movement to develope an Australian Standard for motorcycle protective wear when to my mind standards are presently in use else wear which are perfectly adequate.

    • Cheers Phil – Woah, that’s a biggie. I guess my thoughts are that, as a buyer of a crash helmet, you need to do your research and try on different helmets to make sure it’s a correct fit (I wrote an article on helmet shell sizes and also a helmet fitting guide to try and help people help themselves). I personally think it’s up to the industry to provide the information, and the users to find that information, try the helmets before they buy and that way they’ll get a correctly fitting helmet. There’s lots of information out there if buyers look and if you really want, and with little effort, it’s perfectly possible to buy a helmet that is US and EU standard approved and scores highly in ‘independent’ testing – such as SHARP – whether or not there’s an Australian standard in addition. But as you imply, but there are several countries that piggy back on European or US standards as both, while they have their detractors, are pretty well thought through and monitored. But you know how it is – politicians love to tinker!
