適用范圍：This part of ISO 13357 specifies a procedure for the evaluation of the filterability of dry lubricating oils,particularly those designed for hydraulic applications. The procedure only applies to mineral-based oils, sincefluids manufactured from other materials (e.g. fire-resistant fluids) might not be compatible with the specifiedtest membranes. The range of application has been evaluated with oils of viscosity up to ISO viscosity grade(VG) 100, as defined in ISO 3448. Within the range described, the filterability as defined is not dependent onthe viscosity of the oil. The procedure is not suitable for some hydraulic oils on which specific properties havebeen conferred by the use of insoluble/partially soluble additives, or by particularly large molecular species.NOTE Filterability is a prime requirement for lubricating oils used in hydraulic systems because of the fine filters usedin this application.This part of ISO 13357 defines a method for assessing the filterability of dry oils. It is necessary to note thatsome oils exhibit poorer filterability characteristics in the presence of contaminating water. ISO 13357-1applies to the investigation of the effect of water and high temperature on filterability, if an oil is used inapplications where the presence of water in the oil is likely.
