Iso 4407 pdf

How do you report the ISO code on used hydraulic oil samples? ISO 4407: In this method, the oil sample is passed through a very fine filter patch to capture particles. An optical microscope is then used to count the particles that are between µm. This method was one of the original methods used for particle counting, but it is extremely time- consuming and is rarely used today. iso 4407: Hydraulic fluid power — Fluid contamination — Determination of particulate contamination by the counting method using an optical microscope Buy this standard.

ISO 4407 was prepared by Technical Committee ISO/ TC 131, Fluid power systems, Subcommittee SC 6, Contamination control and hydraulic fluids. This second edition cancels and replaces the first edition ( ISO 4407: 1991), which has been technically revised. In Tribocare, we utilise the ISO 11500 method to report the ISO Code on Used Hydraulic Oil Samples. This is included in our standard test scope of our UOA program. The operation manual for ME engines recommends testing the oil cleanliness regularly, including a particle count in accordance with ISO 4406. How do you count particles in ISO 4407? ISO 4407 – Oil Cleanliness Oil cleanliness is a measure of the level of particle contaminants in the oil, including both insoluble and hard particles. Acceptable oil cleanliness levels are often determined by Original Equipment Manufacturer ( OEM) recommendations and can be controlled through proactive maintenance methods. ISO 11500: This method, which is the most widely deployed method today, uses an optical particle counter. A laser or white light is focused on a capillary detection zone. As the oil sample passes through the detection zone, the particles create a shadow on a photocell detector.
