Oil analysis (OA) is the laboratory analysis of a lubricant's properties, suspended contaminants, and wear debris. ''OA'' is performed during routine predictive maintenance to provide meaningful and accurate information on lubricant and machine condition. By tracking oil analysis sample results over the life of a particular machine, trends can be established which can help eliminate costly repairs. The study of wear in machinery is called tribology. Tribologists often perform or interpret oil analysis data. OA can be divided into three categories: # analysis of oil properties including those of the base oil and its additives, # analysis of contaminants, # analysis of wear debris from machinery, ==Oil sampling== Oil sampling is a procedure for collecting a volume of fluid from lubricated or hydraulic machinery for the purpose of oil analysis. Much like collecting forensic evidence at a crime scene, when collecting an oil sample, it is important to ensure that procedures are used to minimize disturbance of the sample during and after the sampling process. Oil samples are typically drawn into a small, clean bottle which is sealed and sent to a laboratory for analysis. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Oil analysis」の詳細全文を読む スポンサード リンク
