When a motorcyclist goes into a shop to buy a helmet and starts reading the stickers and labels on the helmets for sale, he or she is likely to have some questions. This is because in spite of interest and lip service to international harmonization, there are still numerous performance standards for motorcycle helmets.
Some are government standards and others issued by private organizations. These standards differ in many ways but are similar in that they measure a helmet’s ability to absorb impact. The effectiveness of the retention system that keeps the helmet on the head is also tested as are accessories such as face shields.

<o:p></o:p>
It is critical to note that helmets have been continually shown to be effective in reducing head injury, regardless of what standard they might meet. The only noteworthy exception is the novelty helmet worn in protest of mandatory helmet use laws. These “helmets” do not meet any standard and cannot be expected to provide meaningful head protection.
<o:p></o:p>
In the United States, there have historically been two helmet standards applicable to motorcycle helmets. The FMVSS 218 or DOT is the mandatory U.S. government standard that all motorcycle helmets must meet to be legal for sale and use on public roads and highways.
<o:p></o:p>
This standard was first issued in 1974 and was updated in 1980 and again in 1988. Much work has been done toward another update in the near future. The second standard is issued by the Snell Memorial Foundation (http://www.smf.org/), a private organization that issues its own motorcycle helmet standard.
<o:p></o:p>
A third helmet standard from the Economic Community of Europe (http://www.unece.org/) (ECE) is actually the most commonly used internationally, the ECE 22.05, required by over 50 countries worldwide. While helmet standards all have the goal of regulating helmet performance for protection of riders’ heads, some performance requirements conflict between standards.
<o:p></o:p>
A major benefit for U.S. riders is that the ECE 22.05 standard does not directly conflict with the DOT standard. Limited testing shows that ECE qualified helmets will also meet the demands of FMVSS 218. Of course, not all DOT helmets will meet ECE 22.05 because the European standard does require testing at higher velocities than DOT.
<o:p></o:p>
Another advantage of the ECE 22.05 standard is the requirement for mandatory batch testing of helmets before they are released to the riding public. What this means to the consumer is the quality of the helmet in meeting the ECE 22.05 standard is assured by a mandatory sample testing of every production of helmets before they leave the factory, not with random testing performed after thousands of helmets with unknown quality are delivered to the dealers.
<o:p></o:p>
No one helmet designed to a particular standard or standards can provide the maximum protection in all types of crashes and no helmet can protect the wearer against all foreseeable impacts. Helmets can be designed to provide additional protection, for example, full-face helmets compared to the open-face types, but added protection comes with a weight penalty.
<o:p></o:p>
How much weight are you willing to wear? If you reject helmets with less coverage, you will end up with a helmet that covers most of your head and weighs about three pounds. By choosing a helmet meeting a high performance standard such as ECE 22.05, you can minimize that weight while maximizing protection.
<o:p></o:p>
Summary <o:p></o:p>
If you’re not comfortable with a helmet that only meets the US Government DOT standard, what do you look for? Historically, American riders have looked for a Snell label but the world is getting smaller and we now have other viable alternatives. The ECE 22.05 standard is used in over 50 European countries, including Germany, a country known for taking a hard line on personal protection. <o:p></o:p>
Helmets certified to the ECE 22.05 standard are approved for competition events by AMA, CCS, FIM, Formula-USA and WERA and are chosen by nearly every professional motorcycle racers competing in world championship road racing, motocross and off road events, including the ultimate sport of Moto GP. Helmets that are certified to both DOT and ECE 22.05 offer the highest level of realistic protection with the added benefit of light weight for day-long comfort and rider performance.

<o:p>I hope this helps us in understanding better the difference between ECE, DOT & Snell approved helmets. :)</o:p>
