INTERNATIONAL ISO STANDARD 4406 INTERNATIONAL STANDARD ISO 4406 Hydraulic fluid power — Fluids — Method for coding the level of contamination by solid particles Transmissions hydrauliques — Fluides — Méthode de codification du niveau de pollution particulaire solide
Understanding ISO Cleanliness Codes - Donaldson The ISO cleanliness codes are derived from International Standard ISO 4406:2017 ISO codes show 3 sets of separated numbers These numbers refer to ranges depicting the number of particles 'larger than' 4 micron, 6 micron and 14 micron per 1mL respectively
iso 4406 cLEANLINESS CODES - Precision Filtration Products The International Organization for Standardization created the ISO standard 4406 to quantify particulate contamination levels per milliliter of fluid at three diameter sizes: 4µ [c], 6µ [c], and 14µ [c]
ISO 4406 - HYDAC Technology Corporation onents Each 3-digit ISO code corresponds to a specific component and recommended micro rating These ISO codes and micron ratings can be used universally (ISO 16889) when comparing the realistic performance of various filter
