respirator bacterial filter tester
The main performance indexes of the respirator bacterial filter tester not only meet the requirements of test instrument b.1.1.1 in Appendix B of technical requirements for medical surgical masks (yy0469-2011), but also meet the requirements of ASTM f2100, ASTM f2101 and European en14683, On this basis, the innovative improvement is carried out, and the method of double gas path simultaneous comparison sampling is adopted to improve the accuracy of sampling, which is applicable to the performance test of the bacterial filtration efficiency of the mask by the metrological verification department, scientific research institutes, mask manufacturers and other relevant departments.
Executive standard: Q / 0212 zrb003-2011 bacterial filtration efficiency (BFE) tester for medical surgical masks
