In 1966 an HMS Stationary Office publication titled, The Jost Report: Lubrication (Tribology) Education and Research began defining the term "tribology" as the science and technology of interacting surfaces in relative motion and of associated subjects and practices. Since then, this term has been adopted universally to integrate the various subjects of lubrication, friction and wear.
Today the American Society for Testing and Materials (ASTM) defines the term "tribology" as the science and technology concerned with interacting surfaces in relative motion, including friction, lubrication, wear and erosion.
The terms "condition monitoring," "oil analysis," and "trend analysis" have been used for about 60 years in monitoring wear rates and contamination levels in machinery in order to facilitate the predictive and preventative maintenance of the equipment. In recent years, condition monitoring has become an important part of all maintenance operations. Because of new technology, it has become extremely accurate in identifying specific wear mechanisms, contamination levels, and oil degradation characteristics within operating machinery.
Condition monitoring can be classified into three main categories:
- Metals analysis: detects wear rates, inorganic contaminants, and inorganic additive levels.
- Physical properties testing: detects contamination from glycol, water, fuel, combustion by-products, particulates, acidity, basicity, residues and viscosity.
- Wear particle analysis: characterizes wear mechanisms, concentration of wear particles, and some contaminates.
Note of Caution:
In the last three decades, there has been a push by private oil analysis companies to perform testing for enormous fleet and plant applications. As a caution, OilMedic advises you that these companies or laboratories may be using modified American Society for Testing and Materials (ASTM) testing methods or tests developed for rapid oil analysis by the laboratory. These programs provide users valuable trending data; however, they may MISREPRESENT their data as being conducted by strict ASTM methods when in fact it was not.
The following is a summary of OilMedic's condition monitoring program's benefits:
- Increases the used value at trade-in by using OilMedic's program history as proof of proper maintenance.
- Detect engine problems early so they can be repaired before they become major expenses.
- Prevent wasting money on early oil changes or repairing engine components needlessly by monitoring both the positive and negative operating parameters.
- Allows you to monitor maintenance practices to verify that maintenance is being done on time.
- Manage your budgets by forecasting the cost of repairs or loss of use downtime.
- Develop a complete profile and history of your investment's performance and to help in evaluating a replacement purchase.
- Assess whether your investment will last the length of time required due to abnormal wear trends.
- Allows a shortened repair cycle, since troubleshooting can be reduced allowing service to go right to the problem.
- Allows you to schedule maintenance downtime.
