GB-XF1000  Bacterial Filtration Efficiency (BFE) Detector

 

  Mask Bacterial Filtration Efficiency (BFE) Detector

 

Standards:

YY0469-2004,YY/T 0969-2013,ASTMF2100,ASTMF2101,EN14683

 

Function:

To test the meaterial/product tensile strength, extensibility at break, peel force, peeling strength and heat-sealing strength,tear, punch, compressed, bending, shearing

 

Application:

It is used to test the percentage of materials containing bacteria suspended particles at the specified flow rate. The dual gas path simultaneous comparison sampling method is used to improve the accuracy of sampling, which is suitable for the performance testing of bacterial filtration efficiency of medical surgical  by metrological inspection departments, scientific research institutes, medical mask manufacturers and other relevant departments.
