WebAll the particles within 1 milliliter of oil would be categorized into five size ranges: 5-15 microns, 15-25 microns, 25-50 microns, 50-100 microns and greater than 100 microns. A chart was used to classify the oil’s cleanliness with a range of 00 to 12, based on the number of particles in each size range. The lower the number, the cleaner the oil. WebThe particle size of solid biofuels and particle-size distribution are determined for a sample of at least 8 L with sieving methods and sieve series selected according to the standard ISO 3301. It is recommended to use sieves with hole diameters of 3.15, 16, 31.5, 45, 63 and 100 mm, if the measurement aims at the determination of conformity with ISO 17225 series. shippingdavis.com
