The method involves determining pressure drop of volumes of a main air pipeline (5) in a railway vehicle (6) associated to supplementary volumes of pipe and hose lines. The pipeline is evaluated as sealed during comparison of a smaller resultant pressure d...

The process involves feeding flow rate into a main air pipe by a pressure controller (1). A pressure drop is measured in the pipe over a measurement period by a pressure sensor (6). A ratio between relationship of exhausting leakage flow volume to the pipe...
