Particle Count (Oil Contamination) (ISO 4406 / SAE AS 4059)

The ISO 4406 standard, published by the International Standards Organization (ISO), provides a method for defining the amount of solid particles in the fluid used in a given hydraulic fluid power system.

In our country, this standard has been published by the Turkish Standards Institute (TSE) with the following title: TS ISO 4406 Hydraulic fluid power - Liquids - The method of coding the pollution level of solid particles.

In hydraulic fluid power systems, power is transmitted and controlled by a fluid that is kept under pressure in a closed circuit. However, hydraulic fluid always contains solid particulate contaminants, which cause serious problems and therefore need to be quantified.

Another standard in this regard is the AS 4059 standard, which is an SAE Aerospace Standard. The full name of this standard is: SAE AS 4059 Aviation fluid power - Cleanliness classification for hydraulic fluids. This standard defines cleanliness classes for particulate contamination of hydraulic fluids and includes methods for reporting relevant data.

In the test, analysis, measurement and evaluation studies carried out in our organization, national and international standards and applicable legal regulations are complied with and reliable and impartial results are obtained. These studies are based on the latest technological equipment, trained and experienced staff and modern methods. Among the numerous tests carried out in this context, there are also particle count (oil pollution) (ISO 4406 / SAE AS 4059) services.
