Application Summary AI generated

This standard defines terminology, visual characteristics, and root causes of damage and failure specific to thrust washers used in plain bearings. It is applied in mechanical engineering contexts for failure analysis, quality control, and maintenance diagnostics of rotating machinery, such as automotive transmissions, industrial gearboxes, and hydraulic pumps. The standard provides a common reference for engineers and technicians to identify wear patterns like scoring, pitting, or cracking, and to determine whether failures stem from lubrication issues, misalignment, or material fatigue.
