BS EN 14021 is a European standard on stone shields for off-road motorcycling that discusses the requirements and test methods for stone shields to protect riders against stones and debris.
BS EN 14021 specifies requirements and test methods for the stone shields to be worn by youths and adults of either sex to provide limited protection against lofted stones and debris while riding motorcycles in motocross and other off-road activities on dirt roads.
BS EN 14021 contains general and performance requirements for the materials utilised and requirements for sizes, shapes, marking and assembly methodology.
Note: BS EN 14021 is not applicable to stone shields for children and for people with chest girth below 75 cm.
BS EN 14021 on the requirements and test methods for stone shields is useful for:
Stone Shields are articulate garments intended for the protection of the chest, optionally shoulders, back and biceps specifically against lofted stones and debris such as those riders often encounter in off-road motorcycling and in allied sports activities where these hazards may exist.
A complete stone shield provides protection to the whole of the torso. The essential part of a stone shield is the breast guard, which may be associated with the shoulder guards, the back guard, and the biceps guards.
BS EN 14021 provides you with guidance on the requirements for breast guards, shoulder guards, biceps guards, back guards, ergonomic requirements, impact performance requirements, test equipment, apparatus, circular probe for surface continuity test, test methods, the information supplied by the manufacturer, etc.
The requirements and test methods provided by BS EN 14021 assist you in improving the performance, quality and strength of the stone shields and ensuring protection for off-road motorcycle riders from the risk of being hit by stones and other flying debris.
With obedience and compliance to BS EN 14021, you can enhance stone shields’ effectiveness and efficacy and manufacture a standardized high-quality product.EN 14021:2003
