This standard covers the safety requirements for all tricycles intended for use by children 8 years and under. While the addition of a push handle does not by itself change the classification of a product from a tricycle to a stroller (or other juvenile product)@ there exist in the marketplace some hybrid products (i.e.@ tricycle/stroller combinations that have canopies@ reclining seats@ and/or restraint systems@ etc.) that are intended and marketed to fulfill both functions. Such products may need to meet the requirements of ASTM F833 (Standard Consumer Safety Performance Specification for Carriages and Strollers) or other applicable standards@ in addition to those of this standard. Purpose The purpose of this standard is to establish nationally recognized safety requirements for tricycles and to provide a basis for common understanding among producers@ distributors@ and users of these products.
