(4) ). Abstract. In this paper, the standard test methods at low temperature of rubber suspension components of railway vehicle are investigated and reviewed. In order to connect the TKR(Trans-Korean Railway)-TSR(Trans-Siberian Railway), it is necessary to evaluate the performance of rubber suspenion components of railway vehicle. In the current Korean Standard, the test method at low temperature of railway vehilce components and the test method of rubber bellows of air spring are specified. But, the specified test temperature is higher than the the operating temperature of TSR railway. So, the in-depth research for the test method and performance evaluation technique of rubber suspension component at low temperature is necessary and current KS code should be adjusted.
