What is Bypass Filtration?
Written for Modern Contract Solutions Magazine in 2014, this article provides a overview of bypass oil filtration and how it differs from conventional full-flow oil filters (Author: Bill Butler, B.A., B.Sc., President, Oil Recycling Technologies Ltd.)
Oil – How Clean Does It Have To Be?
This article explains the importance of clean oil and how dirty oil negatively affects the health and life of machinery over time (Mike Sondalini & Don Irvine, Lubrication & Fluid Power, January-February, 2004)
Understanding ISO Particle Counts
ISO codes are a unit of measuring the cleanliness of hydraulic and other non-combustion oils. This document illustrates how an ISO code is assigned to a sample once a particle count is obtained by the spectrometer in the lab, based on the volume of dirt it counts in 3 different size categories contained in 1 ml of fluid.
Recommended ISO Cleanliness Levels for Non-Combustion Oils
Rates of mechanical wear are affected by oil pressure and the volume and size of particulate it contains. Some components with fine tolerances such as servo valves, require super clean oil to function properly. The type of component and the operating pressure of the oil, will determine how clean the oil should be to minimize mechanical wear and maximize the life of the equipment.
Where does your hydraulic oil fall on the ISO oil cleanliness scale?
The volume of dirt in non-combustion oils such as hydraulic oil is measured and assigned a cleanliness code. In 1964 the NAS scale was created and counted 5 different categories of particle sizes per 100 ml of fluid. The NAS method has since been replaced by ISO. Since 1991 the International Standards Organization (ISO) 4406, assigns a 3 digit code, by counting the number of particles >4, >6, >14 microns in size per 1 ml of fluid, providing a much more concise measurement of solid contamination. For example, new unused hydraulic oil should not contain more than 10,000 particles 4 microns in size or greater, per 1 ml of oil. Once you test your oil, you can see where it falls on the cleanliness scale.
Common Types of Mechanical Wear in Industrial Equipment
With the aid of oil sample analysis, one can identify common types and potential sources of mechanical wear in Industrial equipment.
Wear Metal Origins In Mobile Equipment
The presence of sub-micron metals helps identify the source of mechanical wear. Oil from a variety of components on mobile equipment can be tested to detect premature wear and problems before a failure takes place.
Potential Source of Spectrometry Metals
Laboratory testing can identify the concentration (ppm) of wear metals and sources of contamination (soot, water, glycol) present in oil.
