This document defines requirements for the testing of lubricated plain journal bearings in test rigs, running under conditions of hydrodynamic or mixed lubrication, during bearing and/or material development. It deals with both static and dynamic loading in solid and multi-layer journal bearings. It is not applicable to the testing of dynamic characteristics of lubricant film in journal bearings applied in calculation of vibration and stability of turbo-rotors.Cross References:ISO 4378 (all parts)ISO 3448ISO 7902-3ISO 4288ISO 7148-2ISO 7905-2ISO 3675ISO 7148-1ISO 7146-1ISO 7146-2ISO 7905-3ISO 4384-1ISO 7902-1ISO 4385ISO 4384-2ISO 7902-2ISO 7905-1ISO 10129ISO 7905-4All current amendments available at time of purchase are included with the purchase of this document.
