The helmet is a safety device and riders must wear it every time they are on a motorcycle. However, are motorcycle owners aware of the different homologations that their helmets can and must have? If you have a motorcycle do not miss this article in order to know the most common regulations on your helmet!
The two most popular helmet homologations worldwide are ECE 22.05 – mainly in Europe – and DOT Helmet Standard – specially used in the USA. Although both have many things in common, they also have some differences and we are going to explain the main aspects of each one.
In order to get the ECE 22.05 homologation the helmets must pass some tests:
- Impact absorption test: It consists in a drop test where the helmet has a head form inside in order to measure the energy transmitted. The acceleration energy must not be more than 275G to pass the test. The impact absorption and rotational forces also must pass some tests.
- Retention system test: It consists in a free-fall drop test of a 10kg weight from a height of .75m. The weight must be attached to the fastened chin strap. In order to pass the test, the displacement must be equal or less than 35mm.
- Chin strap buckle system test: It consists in testing the slippage under loan, abrasion resistance and tension failure load. Furthermore, there are tests for ease of release and durability of quick-release buckle systems.
- Surface of the helmet test: It consists mainly in an abrasion resistance test on the surface of the helmet.
- Rigidity of the shell test: It consists in measuring the grade of deformation of the helmet while load is applied up to 630 Newtons.
Moreover, the peripheral vision must be an arc of 105º from the helmet midline. There are also environmental conditions tests and requirements for retroreflective materials.
In the label we can find the different types of protection:
- /NP: Helmets that have a non-protective removable chin guard.
- /J: Helmets that don’t have a chin guard.
- /P: Helmets with a protective chin guard.
On the other side, there is the DOT Helmet Standard. As we have mentioned, the DOT Helmet Standard is pretty similar to the ECE 22.05 homologation although they have some differences.
The points in common between both regulations are:
- Impact absorption test: Like the ECE 22.05, the DOT Helmet Standard also apply this test through the helmets although is not exactly the same.
- Retention system test: Another point in common between both regulations is the retention system test. The main differences between both is that in the DOT Helmet Standard the weight applied to the fastened chip strap is heavier.
Furthermore, the peripheral vision in both cases must be exactly the same; at least 105º from the helmet midline.
Nevertheless, we can also find differences between both homologations. The most important ones are:
- Penetration resistance test: It consists on dropping a piercing test striker to the helmet from a particular altitude. The striker must not penetrate the helmet and contact the head-form in order to pass the test.
- Countries in which the homologations are accepted: While the ECE 22.05 homologations is accepted in all Europe and other countries such as Australia, Japan or South Africa, the DOT Helmet Standard is the official homologation for the United States.
- Product labelling requirements: Labelling requirement are completely different in both homologations. In the case of the DOT Helmet Standard, the requirements are:
- Producer’s name
- Model number
- “DOT” below the producer’s name
- “FMVSS 218”
- It is necessary to mention the word “Certified”
After reading the article, you should be able to check before buying a helmet if it has the accepted homologation for the country where you will ride your bike. Remember that all Westt’s helmets have the ECE 22.05 homologation. Enjoy the ride!
