Particle count oil analysis
Particle counting is not intended to identify the type of particulate matter. Other techniques such as atomic emission spectrometry and analytical ferrography were created. How the particle count is performed. As with all oil analysis tests, it is vital that sampling ensures that, in the sample bottle, we have what is actually inside the system. When to use Particle Counting Analysis . Particle counting is probably one of the best tests there is for maintaining system cleanliness. The point of contention lies with whether or not particle count is an appropriate test for all fluid types and systems. Particles in oil accelerate the ageing of oil and shorten its service life. Particularly when checking hydraulic, turbine and other low-viscosity oils, the pollution level is determined based on ISO 4406 by counting the size and number of particles in the laboratory with help from automatic particle counters (APC). This article will answer the following questions. Is my lube oil contaminated? Why do lubricating oils become contaminated? Is my oil filter working and which oil filter should I use? What is a ISO4406, ISO4407, NAS1638 or SAE4059 Particle count? What sizes of particles are tested in ISO 4406 Analysis? How small are the particles my filter removes?
Understanding ISO Codes Though particle counting is reported as an actual count of the number of particles (of a given size, per ml of fluid), most specifications and limits simply refer to ISO codes.
Particle counts are determined cumulatively (i.e. > 4 μm, > 6 μm and > 14 μm) and coded Fluid testing in lab settings is recommended for oil aging parameters,. Our comprehensive range of services, including oil, hydraulic fluid, fuel, debris and filter analysis, is tailored to your specific requirements so you always have By noting the requirements of the standard, particle counts can be accurately converted to contamination levels. Page 2. 68. ISO Cleanliness Code. Hydraulic Fluid Wear Rate monitors and tracks metal wear particles, contaminants and oil additive Monitoring your components. When S·O·S oil analysis identifies an increase in the concentration of of tests that includes Particle Count. Fighting an unseen This monitoring can be conducted with oil particle counting and measurements of moistness, viscosity, acidity and temperature. By using instruments such as a The scanning process verifies the automatic particle count to identify samples needing special preparation. This provides confirmation of automatic counter results,.

Particles in lubricating and hydraulic oils are detrimental as they increase wear, clog filters, and accelerate oil degradation. Particle analysis assesses the Particle Count Analysis: Industry Standard Test for determining solid contamination levels in oil—Given as a 3-digit ISO Code Reading based on actual counts at This edition of Oil Analysis 101 focuses on particle counting and related standards. Considered by many to be the single most important test for used oil analysis, whether you are conducting onsite particle counting, or relying on a commercial lab, there can be no doubt that a host of problems can be quickly and easily determined by monitoring the number and size-distribution of particles in an oil sample.
of the In-service Oil Analysis Handbook. It has been a few years since the publication of the first edition of Spectro Scientific’s In-Service Oil Analysis Handbook. Our original goal was to compile a comprehensive reference book of common in-service oil analysis techniques to help readers understand and choose the right technique and
ISO-3 Particle Count Analysis. Bureau Veritas includes particle count measurements and evaluations for six (6) different micron ranges, including particulates sized at or below 4µm. Filter manufacturers, OEMs and fluid analysis customers are recognizing the vital importance of particle measurements in this smaller range. Particle count – Particle counts measure the relative cleanliness of a fluid. This can be performed at different particle sizes from 4 microns all the way up to 70 microns. The most common cleanliness method is the ISO code system that measures the number of particles at 4, 6 and 14 microns. Particle Count Particle Count now comes into play; it can quantify particles from one micron to greater than 200 microns in size. So it can detect additional signs of abnormal wear and dirty oil that Spectrographic Analysis may not catch. But it counts all particles, both metal and nonmetal, and can’t distinguish between the two. Laser light blocking particle counters, or optical particle counters (OPC’s) are the traditional instruments used for in-service oil analysis. A light source, typically a laser, passes through a sample. The reason why we test particle count is because some particles in the oil can cause damage to the machine, particularly hydraulic equipment. Particles can cause scratching of the machined surfaces and, as a result, cause more wear. The damage compounds until you have major failures.
Our Lube Oil Analysis monitors the health of oil-lubricated equipment with a comprehensive testing slate: Wear, Oxidation and Physical Particle Count. Particle
Understanding ISO Codes Though particle counting is reported as an actual count of the number of particles (of a given size, per ml of fluid), most specifications and limits simply refer to ISO codes. The unit of measure for particle count data is “particles per milliliter of sample.” The particle counters used in laboratories incorporate much more than a milliliter of sample. During the testing process, approximately 100 milliliters of sample are taken into the instrument. The numbers of particles are counted based on this value.
A particle counter is an instrument that detects and counts physical particles. Recorded video is then analyzed by computer software to measure particle types, installed on the equipment, operated in a laboratory as part of an oil analysis 5.1 This test method is intended for use in analytical laboratories including onsite in-service oil analysis laboratories. 5.2 Hard particles in lubricating or fluid power
