ABOUT SNELL MEMORIAL FOUNDATION

Though the name William "Pete" Snell may not be familiar, anyone who enjoys motorcycling, automotive racing, skiing, horseback riding, bicycling, in-line skating and/or skateboarding, they should know about the Snell Memorial Foundation.

As a memorial to Pete, a group of scientists, physicians, racing colleagues and friends teamed together in a dedicated effort to promote research, education, testing and development of standards geared to improve the effectiveness of automotive racing helmets. Through their work, the Snell Memorial Foundation was established in 1957. The Foundation has a Board of Directors that oversee the Foundation's operations. The board is comprised of Medical Doctors and Ph. Ded research scientists and engineers, all of which have distinguished themselves in the areas of safety and/or head injury.

Today, Snell is known for its ongoing work in setting, maintaining and continually upgrading the most authoritative helmet standards in the U.S. and throughout the world. Snell tests thousands of helmets each year and maintains its objectivity by remaining independent of helmet manufacturers, as well as local and national governments. Its state-of-the-art testing facility is located in North Highlands California, just outside Sacarmento.

Helmets meeting Snell Standards provide the highest level of protection available. Snell Standards significantly surpass those set by the U.S. Department of Transportation (DOT), the American National Standards Institute (ANSI), the American Society of Testing Materials (ASTM) and the U.S. Consumer Products Safety Commission's 16 CFR Part 1203.

In order to continuously monitor the quality of helmets being sold to the public, Snell purchases and tests samples of currently certified helmets from the marketplace. These helmets are tested only in Snell labs by Snell technicians. Should a currently certified helmet fail, the helmet manufacturer must take corrective action to Snell's satisfaction.

To take advantage of technical and research development and to provide the highest degree of safety to consumers, Snell Standards are updated about every five years. Updates are based on new Scientific Research and available manufacturing technology.
The Snell safety helmet standards are recognized in the U.S. and worldwide through support of the following organizations:

SNELL是要求帽子本身強度.....
但是DOT是要求帽子吸收衝擊的能力.......
