1.1 This specification covers performance requirements for helmets manufactured for use by infants and toddlers as passengers or operators of nonmotorized vehicles intended for their use. 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 as noted. 1.3 Partial utilization of this standard is prohibited. Any statement of compliance with this specification must be a certification that the product meets all of the requirements of this specification in their entirety. A product that fails to meet any one of the requirements of this specification is considered to have failed this standard, and should not be sold with any indication that it meets parts of this standard. 1.4 Headgear that complies with this and other standards may proclaim uses as described in those standards as certified by the manufacturer. 1.5 This standard is subject to revision at any time by ASTM.
