ISO 4210-4 specifies the braking test methods according to ISO 4210-2. This International Standard has been developed in response to demand throughout the world, and the aim has been to ensure that bicycles manufactured in compliance with this International Standard will be as safe as is practically possible. The tests have been designed to ensure the strength and durability of individual parts as well as of the bicycle as a whole, demanding high quality throughout, and consideration of safety aspects from the design stage onwards. The scope has been limited to safety considerations and has specifically avoided standardization of components. If the bicycle is to be used on public roads, national regulations apply and the bicycle can be equipped with a lightning system. Statement of WG regarding the test methods for the braking performance: For the purpose of improvement of repeatability and reproducibility, and considering the applicability to all types of bicycle and the size and influence of the operator, the machine test method reflects today´s state of the art and is preferred to the track test method. Unless there is evidence of improvement of the test track method in the future, make this method informative for the next revision. Users of this International Standard are invited to provide their feedback to the ISO/TC 149/SC 1. The body responsible for this standard is NA 112-06-01 AA "Fahrräder für allgemeine und sportliche Benutzung" ("Cycles for common and athletic use") at DIN.
