On a two-wheeler, a crash Helmet is undoubtedly the most crucial equipment in terms of passive safety. Active safety is just as vital, and well-engineered modern motorcycles with rider aids like ABS and traction control go a long way toward improving the rider's safety net. However, in the unfortunate event of an accident, your safety equipment will be the only thing standing between you and physical injury. A helmet, which protects the rider by covering the most essential portion of his or her body, the head, in the terrible case of a crash, is the single most crucial piece of safety equipment. There are now technical certificates that must be carried by helmets sold in specific countries and continents to verify that they meet specified minimum quality and safety requirements. As of now, there are three widely used helmet safety standards in the globe. The first is DOT (Department of Transportation) certification from the United States. This certification is required for every helmet used on the road in the United States. The ECE (United Nations Economic Commission for Europe) standard is a certification that is recognized by well over 50 countries, as well as the majority of racing organizations around the world. In addition to these two government-regulated certificates, the Snell Memorial Foundation — a private non-profit testing organization – offers an optional Snell certification. In the UK, you can get SHARP certification, while in Australia, you can get CRASH certification. Because the last two certifications aren't as well-known as the first three, we'll focus on what DOT, ECE, and Snell helmet certifications involve in this post. We'll go over the exams that helmets seeking for these certifications must pass in detail. We'll also go through the distinctions between the testing methodologies used by the DOT, ECE, and Snell helmet certifications. So, let's get started!
To begin with, while the test methodologies for all three certifications differ slightly, there are numerous similarities as well. For example, while being crash tested, test helmets are frequently secured to a head form in all three tests. These head shapes are essentially dummies, similar to the crash test dummies used in automobile crash testing. The shape of these head forms varies depending on the testing organization, but they are all equipped with scientific tools to precisely assess the damage done when they are struck.
Helmet Certification by the Department of Transportation
The United Nations of America's Department of Transportation (DOT) standard is unique. Although the certification is widely acknowledged internationally as a sign of trust for helmet safety, it is overseen and enforced by the country's National Highway Traffic Safety Administration (NHTSA). Helmets that comply with DOT standards must meet strict manufacturing quality requirements, as well as pass stringent crash, penetration, and retention system testing. The test helmets competing for DOT certification are designed to drop from a pre-determined height on two distinct types of surfaces, or anvils. The resulting G-force replicates a crash situation when the vehicle collides, and the impact is measured using scientific instruments. The crash test is carried out twice on each test helmet by the DOT to replicate many hits during a single crash. In addition to a crash test, a penetration test is carried out using a hard, pointed object to guarantee that sharp objects do not breach the helmet's shell. The helmet's straps are also evaluated for strength and capacity to keep the helmet in place after a collision. After all, no amount of strength in a helmet shell can help the rider if it flies off after an accident. helmets with DOT certification should also provide a peripheral view of at least 105 degrees from the Helmet's center. Any protrusion on the helmet'ssurface must be no more than 5mm.
The DOT test technique involves dropping the test helmet from a fixed height of 1.83 meters, generating a G-force equivalent of 400G, then crashing it into flat and spherical anvils. A pointed striker is dropped upon the helmet for the penetration test to see if it can pierce through the shell and the EPS lining. The helmet fails the test if the striker makes any contact with the head form or does any other harm to it. The helmet's retention straps are put to the test in the retention system test. The load on the straps begins at 22.7 kilograms, is applied for 30 seconds, and then gradually increases to 136 kilograms for 120 seconds. To pass the test, the retention system must not displace more than a given amount.
A key feature of the DOT certification, and one that is frequently criticized, is that a helmet manufacturer does not need to obtain DOT certification from the NHTSA in order to sell their products on the market. The system is based on the notion of self-certification, in which manufacturers test and identify their helmets as DOT certified without the involvement or oversight of the government. The NHTSA then selects helmets on the market at random and tests them for conformity with DOT criteria. If a helmet on the market fails the DOT test, the entire batch must be recalled. For each substandard helmet, the penalty might be as high as US$ 5000. Because the stakes are so high, genuine helmet manufacturers put their products through rigorous testing before releasing them on the market with DOT certification. However, there is a flaw with this system in that if a manufacturer distributes a defective model without sufficient testing, the certified helmets on the market constitute a risk to individuals who wear them. Buyers of such helmets are at risk until the fault in the helmet is identified and corrected.
Helmet Certification by ECE
The ECE helmet safety standard is the most widely used worldwide, taking its name from the United Nations' Economic Commission of Europe. This accreditation is required in over 50 nations for helmets sold within their borders. Not only that, but the ECE certification is recognized by organizations such as the AMA, WERA, FIM, CCS, Formula USA, MotoGP, and others for practically all competitive motorsport events. While the basic process for testing helmets under ECE criteria is comparable to that used by the DOT, it is frequently seen as more demanding than the American equivalent. Its acceptance in well-known motorsport is another reason why many helmet buyers prefer it to DOT.
One significant distinction between DOT and ECE certification is that DOT simulates two collisions in the same location on the helmet, but ECE only does so once. A DOT-certified helmet, on the other hand, is often assumed to pass the ECE test, and vice versa. However, many people believe that ECE testing is the most up-to-date and comprehensive. The additional testing that ECE certified helmets must pass in order to rECEive certification are likely one element that contributes to its perceived ‘added' legitimacy. An ECE certified helmet must additionally undergo abrasion resistance testing in addition to the tests stated above as part of the DOT standard. The material of the chin strap is tested for slippage, and the retention mechanism is subjected to a higher load of over 300 kg. The visor is treated as an integral part of the helmet under ECE rules, and the shell of the helmet is tested for deformation under a weight of 68 kg.
Certification for Snell helmets
The Snell Memorial Foundation is a private, non-profit, independent organization that works to improve rider or driver safety by facilitating the creation and testing of better, safer helmets. Unlike ECE and DOT, which are government bodies for helmet certification, the Snell Memorial Foundation is a private, non-profit, independent organization that works to improve rider or driver safety by facilitating the creation and testing of better, safer helmets. The Snell Certification is named after William "Pete" Snell, a well-known race car driver who died from brain injuries after a mishap. Pete was wearing a helmet that passed current safety standards, yet it wasn't enough to keep him alive. Every five years, the Snell specifications for helmet safety are modified. Snell, M2015 are the most latest ones, and they are fairly similar to the M2010 guidelines.
In general, Snell is thought to be a better helmet safety standard since helmets that receive the certification must pass a broader set of tests that are deemed more rigorous, though not more effective in the event of a crash. Because Snell is a non-profit organization, helmet manufacturers can choose to be certified, as opposed to DOT or Z, which are both mandated. Another significant difference in the Snell Memorial Foundation's operation is that it not only examines helmets after they are manufactured, but also assists manufacturers with testing during the manufacturing process.
Generally speaking, Snell is supposed to be a superior helmet safety specification, as the helmets receiving the certification have to undergo a wider range of tests, which are considered more rigorous, if not more effective in the case of a crash. Since Snell is a non-profit organization, the certification is voluntary for helmet makers, unlike DOT or Z, which are mandatory. Another big difference in the functioning of the Snell Memorial Foundation is that it not only tests helmets post production, but also helps manufacturers with testing during the design and prototyping process to create better, safer helmets.
