Foreword
This standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T .20100-2006 "stainless steel fiber sintered filter felt".
This standard and GB/T .20100-2006 standard compared to the main changes are as follows.
--- increase the provisions of the CY, DY, GY series of filter felt and marking method;
--- increase CY, GY, DY series of products bubble point pressure, porosity, pollution capacity, thickness and other technical indicators;
--- increase 60,80,100μm product specifications;
--- delete the definition of filtration efficiency and indicators;
The definition and index of breaking strength are removed.
This standard is proposed and centralized by the National Committee for Standardization and Standardization of Particle Characterization and Screening (SAC/TC168).

3 terms and definitions
3.1
Filter than filterratio
The ratio of the number of contaminant particles in a unit size greater than a given size [X (c)] is expressed in βX (c), see
Formula (1).
βX (c) =
Nu
Nd
(1)
Where.
Nu --- filter felt upstream oil volume per unit volume greater than X microns;
Nd - the number of particles in the unit volume of the downstream oil of the filter felt greater than X microns.
Note 1. βX (c) indicates the filtration capacity of the filter felt for particles larger than the size of X.
Note 2. The lower scale "(c)" of βX (c) indicates that βX is measured and calculated using an automatic particle counter calibrated in accordance with ISO /IEC 15854. Without the next footer, table
The betaX is measured and calculated using a particle counting device calibrated by other methods.
3.2
Filtering accuracy filter-rating
When the filter ratio of the filter felt βX (c) ≥ 20, the corresponding particle size [X (c)] value for the filter felt filter accuracy.
3.3
Permeability airpermeability
At a pressure gradient, the unit time gas passes through the volume value of the felt per unit area.
3.4
Bubble point pressure bubble-pointpressure
The minimum pressure required to pass the gas through the first bubble produced by the liquid impregnated filter felt.
