DRK-1000 Mask Bacterial Filtration Efficiency (BFE) Ntes

Lub ntsiab kev ua tau zoo ntawm DRK-1000 daim npog qhov ncauj kab mob pom kev ua haujlwm zoo (BFE) tsis tsuas yog ua tau raws li qhov yuav tsum tau ua ntawm cov cuab yeej ntsuas B.1.1.1 hauv Cov Ntawv Ntxiv B ntawm "Kev Kho Mob Lub Ncauj Ncauj Kev Kho Mob" YY0469-2011, B.1.1.1 Test Method of Bacterial Filtration Efficiency (BFE) Test Method, Thiab nws kuj ua tau raws li cov kev cai ntawm ASTMF2100, ASTMF2101, European EN14683 cov qauv, thiab ntawm lub hauv paus no, kev txhim kho tshiab tau ua. Txoj kev siv roj av dual ib txhij ua piv txwv yog siv los txhim kho qhov tseeb ntawm cov qauv. Nws yog tsim rau cov chaw kuaj xyuas metrological. , Cov koom haum tshawb fawb tshawb fawb, cov tuam txhab daim npog ntsej muag thiab lwm lub koom haum cuam tshuam los ntsuas qhov ua tau zoo ntawm daim npog ntsej muag cov kab mob pom kev ua haujlwm zoo.
