Yuav ua li cas xaiv lub npog ntsej muag?
Nkag siab ASTM F 2100-19 / EN14683: 2019 STANDARDS
Xaiv lub npog ntsej muag tsim nyog rau ib txoj haujlwm tshwj xeeb yog ib qho tseem ceeb ntawm koj Cov Khoom Siv Tiv Thaiv Tus Kheej (PPE) raws tu qauv. Txawm hais tias lub npog ntsej muag yuav zoo sib xws, txhua lub npog ntsej muag muaj qhov sib txawv tseem ceeb cuam tshuam rau qhov zoo thiab qib ntawm kev pom. Kev nkag siab txog qib ASTM kev ua tau zoo ntawm txhua lub ntsej muag lub ntsej muag tuaj yeem pab ua kom cov txheej txheem xaiv tau yooj yim dua thiab xyuas kom meej tias koj lub npog ntsej muag yuav muab kev pom zoo.
Cov ntaub ntawv npog ntsej muag kho mob tau them raws li ASTM cov lus qhia tshwj xeeb raug xaiv los ua ib lossis ntau dua
raws li qib kev ua tau zoo raws li qhov cuam tshuam kev ua tau zoo ntawm cov khoom siv

SynthritlC Ntshav * sawv cev rau lub npog ntsej muag tiv thaiv kev nkag mus los ntawm cov ntshav hluavtaws hauv siab (mmHg). Nws ntsuas lub peev xwm ntawm lub npog ntsej muag cov ntaub ntawv tsim kho kom txo qis cov kua dej nkag mus los ntawm cov khoom thiab muaj feem cuam tshuam nrog tus neeg hnav. Qhov siab dua cov kua tsis kam (filtration), qhov kev tiv thaiv zoo dua.
BFE (Bacterial Filtration Efficiency) sawv cev rau feem pua ntawm aerosol particulates lim ntawm qhov loj ntawm 3 microns.
PFE (sub-micron Particulate Filtration Efficiency) sawv cev rau feem pua ntawm cov submicron particulates lim ntawm 0.1 micron. PFE yog qhov ntsuas ntawm qhov ua tau zoo ntawm lub npog ntsej muag hauv kev lim cov khoom dhau los ntawm nws. Qhov loj ntawm cov khoom lim dej yog qhov tseem ceeb.
DELTA P (Differential Pressure) sawv cev rau lub siab poob thoob plaws lub npog ntsej muag lossis tiv thaiv huab cua ntws hauv
mmH2O/cm2. Qhov no txiav txim siab ua tsis taus pa ib qho siab dua Delta P, qhov tsawg dua qhov ua pa, tab sis qhov pom zoo dua.
Flammability ntsuas cov nplaim taws kis ntawm cov khoom siv npog ntsej muag.
