Standard Specification for Helmets Used in Recreational Bicycling or Roller Skating
ABSTRACT
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. Helmets shall be impacted with anvils centered on or above the prescribed test line. The test anvils can be oriented in any horizontal, centered position. One each hot, cold, wet, and ambient helmet shall be impacted using the flat and hemispherical anvils only. The curbstone anvil shall be used to impact one time each of the second set of four samples, one conditioned under each of the four conditioning environments. The peak acceleration of the impulse during the impact shall be measured. The ambient helmet shall be subjected to the positional stability (roll-off) test, while the hot, cold, and wet helmets shall be subjected to the dynamic strength retention test.
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 F1446, 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.
1.4 This standard is subject to revision at any time by ASTM. It must be reviewed every five years and if not revised either reapproved or withdrawn. References to the standard must include the version date. No references to a version that has been replaced or withdrawn shall be placed on any product or its packaging manufactured more than 24 months after the effective revision or withdrawal date. Go to astm.org to verify the latest version of this standard.
Note 1: The current edition of this standard was approved on June 1, 2018.
1.5 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.
