ASTM F1447-02

Standard Specification for Helmets Used in Recreational Bicycling or Roller Skating

SCOPE
1.1 This specification covers performance requirements for helmets manufactured for use by recreational bicyclists or roller skaters. This specification recognizes the desirability of lightweight construction and ventilation; however, it is a performance standard and is not intended to restrict design.
1.2 All testing and requirements of this specification shall be in accordance with Test Methods F 1446, except where noted herein.
1.3 Partial utilization of this specification is prohibited. Any statement of compliance with this specification shall be a certification that the product meets all of the requirements of the specification in its entirety. A product that fails to meet any one of the requirements of this specification is considered to have failed the standard and should not be sold with any indication that it meets parts of the standard.
