Bacterial Filtration Efficiency (BFE) tester
The main performance indexes of the mask bacterial filtration efficiency (BFE) tester not only meet the requirements of the test instrument of appendix B bacterial filtration efficiency (BFE) in YY0469-2004, but also meet the requirements of ASTM F2100, ASTM F2101, European EN14683 of the American Institute of Testing Materials. On this basis, innovative improvements have been made to improve the accuracy of the sampling by using the double-air simultaneous sampling method,applicable to metrology departments, research institutes, mask manufacturers and other related.
The main performance indicators not only meet the requirements of the B Bacterial Filtration Efficiency (BFE) test method in Appendix B of the Technical Requirements for Medical Surgical Masks (YY0469-2004) B.1.1 test instrument, but also meet the requirements of the ASTM F2100, ASTM F2101, European EN14683 standards of the American Society of Test Materials. On this basis, innovative improvements have been made to improve the accuracy of the sampling by using the double-air simultaneous sampling method. It is suitable for the performance test of bacterial filtration efficiency of masks by metrological verification departments, scientific research institutes, mask manufacturers and other relevant departments.
