Proposal to establish quality criteria for applied brake torque datasets at 250 Hz sampling rate by calculating rising criterion, maximum criterion, and stability criterion for each brake event. Rising criterion measures time to reach ninety per cent of nominal brake torque and overshoot at brake event start. Maximum criterion calculates maximum brake torque weighted by nominal specific kinetic energy. Stability criterion reports average brake torque and root mean squared error weighted by nominal specific kinetic energy. Results show variation across laboratories. Further investigation necessary for different brake types, threshold definition for failed brake events, and inclusion of method and criteria reporting in event based file.
