This European Standard specifies the minimum coverage to be provided by motorcyclists’ chest protectors. This European Standard contains the requirements for the performance of the protectors under impact and details of the test methods, requirements for sizing, ergonomic requirements, and requirements for innocuousness, labelling and the provision of information.

If the product is only intended to protect against lofted stones (commonly used in Motocross riding) readers are invited to refer to EN 14021:2003 instead.
