Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 6886-2008 "sintered stainless steel filter components." This standard compared with GB/T 6886-2008, the main change
As follows.
--- Increase the grade of SG001 (filtration precision 1μm) sintered stainless steel filter element;
--- Increase bubble test aperture requirements;
--- The permeability coefficient is replaced by air permeability, and the original data has been adjusted;
--- Change the breakdown voltage strength to compressive strength;
--- Component model, size and size deviation made the appropriate adjustments.
This standard is proposed by China Nonferrous Metals Industry Association.
This standard by the National Non-ferrous Metal Standardization Technical Committee (SAC/TC243) centralized.
This standard was drafted unit. West Baode Technology Co., Ltd., Northwest Nonferrous Metal Research Institute, Chengdu Yi State Science and Technology Co., Ltd., colored
Metal Technology Economics Research Institute.
The main drafters of this standard. Dongling Feng, Dai Chen, talk Ping, Cao Bailiang, Gao Lin, Wu Yanhua, Zhang Xu, Dou Weying, Xue Cui Cui.
This standard replaces the standards previously issued as.
--- GB/T 6886-1986, GB/T 6886-2001, GB/T 6886-2008.

3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Filtration efficiency filtrationefficiency
ηx
At a given fluid particle concentration and flow rate through the filter element, the filter element is greater than a given size (x) of solid particles
Filter out the percentage.
That is, ηx =
N1-N2
N1 ×
100%
In the formula.
N1 --- filter element upstream unit liquid volume greater than a given size (x) of the number of solid particles;
N2 --- filter element downstream of the unit liquid volume greater than the same size (x) of the number of solid particles.
