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
