I-DRK227 Isihloli sokungena kwegazi sokwenziwa semaski yokuhlinzwa

Izinkomba zobuchwepheshe:

1. Idivayisi yokulungisa isampula egqagqene ingalingisa isimo sangempela sokusetshenziswa kwemaski, ibeke eceleni indawo yokuhlola ngaphandle kokucekela phansi isampula, futhi isabalalise igazi lokwenziwa endaweni eqondiwe yesampula.

2. Umshini okhethekile womjovo wokucindezela okungaguquki ungakhipha umthamo othile wegazi lokwenziwa ngesikhathi esilawulwayo.

3. Ingakwazi ukulingisa ngokugcwele ijubane lomjovo elihambisana nesilinganiso somfutho wegazi womzimba womuntu ongu-10.6kpa, 16kPa kanye no-21.3kpa.

4. Ipuleti eligxilile eliqondiwe lisethelwe ukuvimba ingxenye yomkhawulo wengcindezi ephezulu yokugeleza koketshezi olujovwe futhi ivumele kuphela ingxenye egelezayo ukuthi ifuthwe kusampula, okwandisa ukunemba nokuphindaphinda kwesivinini soketshezi esifuthwe kusampula.

[ Samazinga] :

Izidingo zobuchwepheshe zomshini wokuphefumula wezokwelapha, ukusebenza kwesithiyo sokungena kwegazi sokwenziwa esingu-5.5

I-YY/T 0691-2008 isisetshenziswa sokuvikela i-pathogen esithathelwanayo ukumelana nemaski yezokwelapha endleleni yokwenziwa yokuhlola ukungena kwegazi (ivolumu egxilile, umjovo ovundlile)

Ubuchwepheshe bemaski bezokwelapha be-YY 0469-2011 budinga idivayisi yokuhlola ukungena kwegazi

I-ISO 22609:2004 imishini yokuvikela igciwane elithathelwanayo indlela yokuhlola imaskhi yezokwelapha ukumelana nokungena kwegazi okokwenziwa (ivolumu engashintshi, umjovo ovundlile)

I-ASTM f1862-07 Indlela Yokuhlola Ejwayelekile Yokumelana Nemaski Yobuso Bezokwelapha ezocitshwa Ngegazi Lokwenziwa (Ukuqagelwa Okuvundlile Kwevolumu Egxilile ngeVelocity Yokwazi)

Imingcele yezobuchwepheshe
