Kaping pisanan, iki minangka standar topeng, dudu merek topeng tartamtu, dudu model topeng tartamtu, dudu fungsi topeng tartamtu, nanging standar topeng, sing dadi standar!

Definisi
kinerja Filter- panyaring dievaluasi kanggo ngukur pangurangan konsentrasi aerosol tartamtu ing udara sing ngliwati saringan.
Agen tes- aerosol sing diasilake sajrone tes kinerja panyaring.
Total Inward Leakage (TIL)- jumlah aerosol tartamtu sing mlebu ing facepiece respirator sing dites liwat penetrasi filter lan bocor faceseal, nalika sing nganggo nindakake serangkaian latihan ing kamar uji.
Inward leakage (IL)- jumlah aerosol tartamtu sing mlebu ing facepiece respirator sing dites, nalika wong sing nganggo ambegan normal sajrone 3 menit ing kamar tes.Ukuran aerosol tes (diameter median count) kira-kira 0,5 mikro meter.
Penurunan tekanan- udhara resistance kena nalika obah liwat medium, kayata saringan respirator.
Adhedhasar tabel ing ndhuwur, cukup kanggo nimbang China KN95, AS/NZ P2, Korea 1st Class, lan Japan DS FFRs minangka "setara" karo US NIOSH N95 lan respirator FFP2 Eropa, kanggo nyaring partikel non-lenga kayata sing diasilake. saka kobongan liar, polusi udara PM 2.5, letusan gunung berapi, utawa bioaerosol (contone virus).Nanging, sadurunge milih respirator, pangguna kudu takon karo peraturan lan syarat perlindungan ambegan lokal utawa priksa karo panguwasa kesehatan masarakat lokal kanggo pandhuan pilihan.
