An Investigation on Standards Creation of Brake friction Materials for Railway Vehicles

철도차량용 제동마찰재 표준규격 제정에 관한 연구

Brake friction materials in railway applications are one of critical elements for acceleration and/or deceleration of vehicle, stop at designated position, and stability of vehicle operation. In this investigation, a comprehensive overview on international standards on brake friction materials, including UIC, JI, and AAR, was conducted to understand the current standards creation trend and collect the related information on brake friction materials with different applications. Moreover, the detailed conditions such as testing conditions and environment, testing items, and materials, were carefully reviewed and compared by each standard. The preliminary results will be used for the creation of Korean railway standards (KRS) on brake shoe materials.
