Brake discs are very complex components in regards of their composition, design, properties and their manufacturing processes. Therefore, a working group is established to work on friction relevant disc specifications. Sub-tasks and correlating sub-teams were already defined. In a first step, a general chapter in regards of nomenclature is prepared, as well as a screening of already existing standards from public domains is carried out. A special focus is given to NVH-relevant items to prepare best-practice recommendations for Eigenfrequency and damping determinations. At Eurobrake 2022, recent work progress of this relevant working group is presented and discussed.
