Обзор требований
Этот обзор пока доступен только на английском языке.
Область применения
This standard applies to single-rider unicycles driven directly by cranks with a single pneumatic wheel and saddle, intended for users aged 6 and above. It is not applicable to unicycles designed for road riding, chain-driven mechanisms, or special competitive sports. Manufacturers must verify the wheel diameter categories to determine specific age applicability.
Технические требования
Chapter 5 of this standard is mandatory and specifies comprehensive safety requirements for unicycles. It covers chemical properties of materials, requiring specific migration limits for certain elements in accessible surface coatings and saddle leather for small unicycles, referencing GB 6675. The standard also details mechanical safety aspects, including the prohibition of sharp edges and strict dimensional requirements for protrusions to prevent injury. Manufacturers must ensure all exposed rigid protrusions are properly rounded. Furthermore, it sets forth structural integrity requirements for critical components such as the fork, wheel, saddle, and pedals. This includes specifications for wheel precision, tire-rim compatibility, and the dynamic durability of pedals and crank assemblies under specified load conditions. Additional requirements cover the operational characteristics of quick-release mechanisms, ensuring they are adjustable, clearly marked, and capable of withstanding specified tightening and release forces without permanent deformation.
Методы испытаний
The standard outlines specific testing methodologies to verify compliance, including: - Chemical migration testing for accessible materials. - Sharp edge testing as per GB 6675. - Fork lateral static load strength test to measure permanent deformation. - Wheel static load and fit strength tests to ensure structural integrity. - Impact strength testing for synthetic resin integrally molded wheels. - Dynamic durability testing for pedals and fatigue testing for crank assemblies. Testing must be conducted in controlled environmental conditions with specified instrument precisions.
