SHIELD STANDARDS BROKEN DOWN
There are many different eye protection standards internationally, and many of our National standards actually vary from state-to-state. The various standards can be somewhat confusing to the average person, but SHOEI’s passion for quality and safety helps to ensure that all of our shields meet, and even exceed, the most relavent standards for motorcyclists. DOT uses the currently valid Vehicle Equipment Safety Commission Standard 8 (VESC-8), which designates material, lens size, optical properties, strength, field of vision, flammability, cleansing capabilities, labeling, identification, and testing procedures to which all eye protection devices must meet and be used by motorcycle riders and passengers. SHOEI shields also meet/exceed the American National Standard for Occupational & Educational Personal Eye and Face Protection Devices (ANSI Z87.1), which is a requirement specific only to motorcyclists in the state of New York. Additionally, SHOEI shields must also pass the tough SNELL requirements. In order to meet this standard, a small 1 gram lead pellet is shot into the shield at roughly 310 mph and must not penetrate the inside of the helmet.
PRODUCTION AND R&D
All current model SHOEI shields are made from high-strength polycarbonate using a sophisticated 3D injection molding process. Although this method is more expensive, it is necessary to create a 3-dimensional curved shield that is optically correct to eliminate any distortion. Injection molding also allows SHOEI to form the mounting apparatus that work together with SHOEI’s quick-release base plate systems, allowing for quick and easy tool-less shield changes. In contrast, some manufacturers are forced to use turbulent base-plate covers because they cannot produce 3-dimensional shields using the “stamping” method.
CLARITY IN OPTICS
DOT/VESC-8 LIGHT TRANSMITTANCE & OPTIONAL TINTS
The DOT/VESC-8 standard requires a light transmission of at least 80% for shields, so it can be used around the clock without any problems. Tinted shields with a lower light transmission of 50%-80% receive the additional “For Daytime Use Only“ label, and are only suitable for use during the day.
