Iso 4406 particle count code#
(2) the ISO Solid Contaminant Code (SAE J1165) and (3) the National Aerospace Standard Code (NAS 1638). We offer three types of automatic particle counting tests: (1) ISO 4406, presently the most commonly used code to express the cleanliness of hydraulic fluids. ISO 4406 classification is based on particle sizes >4 µm, >6 µm and. The processes used to determine oil cleanliness and cleanliness classes are defined under ISO 4406 and SAE 4059. After the particles are counted, the oil is classified according to cleanliness. For the total mass of particles by filtration, consider ASTM D4898. Here, laser sensors are used to determine the number and size of the particles. If you are interested in the total volume of sediment consider ASTM D2273, FTM 3101 or ASTM D91. Optical microscopy helps to identify the types of particles in cases of high automatic particle counts. Automatic optical particle counting is the best choice for most samples – it usually yields accurate results and gives an in-depth breakdown of particle sizes in the sample. Commonly known as the ISO Code, ISO 4406 reports data in the form of X/Y/Z, where X, Y, and Z are integers whose values correspond to the number concentration of particles larger than 4, 6, and 14 m (c). Related tests offered by Petro-Lube: We offer optical microscopy tests (ARP 598B, WQTM 611, ASTM F312, FTM 3013, FTM-3009) and Automatic Optical Particle Counting (ISO 4406, ASTM D6786, FTM 3012, SAE J1165, SAE 749) to determine the cleanliness of fluids. ISO 4406 provides a standardized method of reporting particle count data. 3 Code Particle Count (2, 5 and 15 micron) Size: Count: Scale >2. The ISO code number refers to the number of particles per 1 ml of oil in larger than each size range. Either one looks at 5 and 15 micron particles or 2, 5 and 15 micron particles. Using an Automatic Optical Particle Counter as per the method, the number of particles in each size category is determined and reported along with the ISO Cleanliness Code. The ISO 4406 code specifies either two or three size ranges for particles.
Iso 4406 particle count software#
The automated microscopic particle count with integrated image analysis software newly installed in the. The first number relates to particles >4 µm, the middle number to particles >6 µm and the number on the right to large particles >14 µm. In this method, the concentration of particles in 3 size categories (≥ 4 µm, ≥ 6 µm and ≥14 µm) is determined and used to establish the ISO Cleanliness Code rating. The purity class according to ISO 4406/1999 is indicated as a composite number, such as 21/18/13. ISO 4406 Table 1 in ISO 4406 provides scale values as a function of particle concentration (particles/mL). The most commonly used standard is ISO 4406 Hydraulic fluid power-fluids-method for coding the level of contamination by solid particles. The ISO Cleanliness Code is a standardized system developed to give a comparative value of the number of particles in a fluid. values associated with concentration at chosen particle sizes. The most common standard used to rate cleanliness is the ISO 4406.

NOTE 5All particle counts are per milliliter. These codes are written in the form of x/y/z, where x, y and z are ISO Codes equivalent to the cumulative counts, per mL, for particle size bands 4 m (c), 6 m (c), and 14 m (c) respectively. (WDA is a vital tool in failure and warranty issues). DiscussionResults are expressed by ISO Codes as specified by ISO 4406. FW/PQ, DR Ferrography and Wear Debris Analysis are probably wiser choices. Contamination of these fluids, from environmental debris, microbial growth, wear, fluid degradation or other sources, may decrease system efficiency, damage components and potentially cause system failure. Diesel engine oil is black and requires different techniques to the tried and trusted laser counting methods. Home page Petroleum Lab Testing Equipment. The number of particles is then converted to what is referred to as the ISO Code or.
According to the ISO 4406:99 standard, the ISO particle count is a measure of the number of particles greater than 4, 6, and 14 microns in every milliliter of fluid.

The particle counter can monitor oil parti. When we speak in terms of cleanliness, we often refer to the ISO particle count of the oil. Hydraulic systems use pressurized hydraulic fluids to transmit power. Oil particle counter KR-170 is a special oil pollution analyzer for measuring the particle size and distribution of oil particle particles in oil monitoring.
