15、ions apply throughout this specification.3.1 Filtration RatioFiltration ratio is the ratio of number of particles greater than a given size (x) in the fluidentering the filter element to the number of particles greater than the same size in the fluid leaving the filterelement. The minimum filtration

16、 ratio is the lowest filtration ratio reported for any one of the ten time intervalsincluded in the multi-pass method for evaluating filter performance per ISO 16889, as modified in 5.6.2. (Thefiltration ratio reported for each time interval is determined by averaging the particle counts for the tim

17、einterval.) The filtration ratio as used herein applies to the use of medium test dust in accordance with ISO12103-1 A-3.3.2 Dirt Holding CapacityThe apparent dirt holding capacity is the actual weight (grams) of the contaminantinjected into the filter test system before the terminal pressure drop i

18、s reached. The retained dirt holdingcapacity is the mass of specific particulate contaminants effectively retained by the filter elements whenterminal pressure drop is reached.3.3 Rated FlowThe rated flow is the flow at which the element is tested for efficiency and dirt capacity. Unlessotherwise in

19、dicated, the rated flow specified in the applicable specification sheet is the maximumrecommended flow rate when using a fluid of the specified viscosity.3.4 Terminal Pressure DropTerminal pressure drop is the maximum specified pressure drop permitted acrossthe filter element to achieve the apparent

20、 dirt holding capacity of the element under test condition.3.5 Pressure DropPressure drop is the differential pressure across a filter element as measured underspecified conditions.4.
