ISO code (ISO )? The primary difference is in the way the particle size is specified and measured. ISO uses particle counter calibrated to ISO 11171, whereas ISO used ISO 4402 counter calibration. ISO 4402 measured a particle for its long chord dimension, but the new ISO 11171 measures a particle by an actual equivalent diameter as measured by Scanning Electron ...

الحصول على السعر· ISO 4406 provides a standardized method of reporting particle count data. 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 µm(c). For hydraulic, engine, and aerospace appliions involving petroleumbased fluids, particle size is .
الحصول على السعرISO codes (fuel contamination) ISO standard 4406:1999 is used to measure contamination in fuel, as well as in hydraulic systems (see page 6).The only difference is that particle counts are usually expressed as per millilitre, rather than per 100ml, so the raw counts are generally 100 times lower. 22 20 000 40 000 21 10 000 20 000 20 5 000 10 000 19 2 500 5 000 18 1 300 2 500 17 640 1300 16 320 ...

Though particle counting is reported as an actual count of the number of particles (of a given size, per ml of fluid), most specifiions and limits simply refer to ISO codes. The ISO codes, according to the ISO 4406:1999 standard, relate to only three different ranges of particles, ≥4 µm/≥6 µm/≥14 µm.
