ABSTRACT This specification establishes a minimum outer diameter for Bicycle Grips and End Closures applied to tubular handlebars mounted on bicycles designed for cyclists who are 12 years of age or younger. It specifies testing requirements for the durability of the ends of the Bicycle Grips and End Closures for all bicycles where the tubular handlebar end axes are oriented within 60 degrees of parallel to the axle axis of the steering wheel. This specification applies to the "BMX" and "Mountain" style tubular handlebars, but not to the "Drop" (also known as road race) style. The following characteristics are covered by this specification: Bicycle Grip outer diameter; Bicycle Grip or End Closure diameter or both; and Bicycle Grip or End Closure retention or both. This specification is not intended to dictate the design, materials, or construction of Bicycle Grips and End Closures. SIGNIFICANCE AND USE 6.1 These tests are intended to address the Bicycle Grip with regard to steering control, durability and potential reduction in injury during an accident. SCOPE 1.1 This specification establishes a minimum outer diameter for the Bicycle Grip or End Closure, and the method for determining if the grip or End Closure meets the diameter. 1.2 This specification checks the following characteristics: 1.2.1 Bicycle Grip outer diameter, 1.2.2 Bicycle Grip or End Closure diameter or both, and 1.2.3 Bicycle Grip or End Closure retention or both. 1.3 This specification establishes testing requirements for the durability of Bicycle Grips and End Closures. It represents a performance standard and is not intended to dictate the design, materials, or construction of those closures. 1.4 Units—The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
