DRK227 Umvavanyi wokungena kwegazi owenziweyo kwimaski yotyando

Iimpawu zobugcisa:

1. Isixhobo sokulungisa isampula esikhuphayo sinokufanisa imeko yokusetyenziswa kwangempela yemaski, sibeke eceleni indawo ekujoliswe kuyo ngaphandle kokutshabalalisa isampuli, kwaye sisasaze igazi lokwenziwa kwindawo ekujoliswe kuyo kwisampuli.

2. Isixhobo esikhethekileyo sokutofa ngoxinzelelo olusisigxina sinokukhupha umthamo othile wegazi lokwenziwa ngexesha elilawulwayo.

3. Iyakwazi ukulinganisa ngokupheleleyo isantya sokutofa esihambelana ne-avareji yoxinzelelo lwegazi lomzimba womntu we-10.6kpa, 16kPa kunye ne-21.3kpa.

4. Ipleyiti ekujoliswe kuyo esisigxina imiselwe ukuvala i-high-pressure edge inxalenye ye-liquid flow flow injected kwaye ivumela kuphela inxalenye yokuhamba ngokuzinzileyo ukuba itshizwe kwisampuli, eyandisa ukuchaneka kunye nokuphindaphinda kwesantya solwelo esifafazwe kwisampuli.

[ Simigangatho] :

Iimfuno zobuchwepheshe zokuphefumula kwezonyango, i-5.5 yokwenziwa komqobo wokungena kwegazi

I-YY/T 0691-2008 isixhobo sokukhusela i-pathogen eyosulelayo kwi-mask yonyango ukuxhathisa kwindlela yokuvavanya ukungena kwegazi (umthamo osisigxina, inaliti ethe tye)

I-YY 0469-2011 iteknoloji yemaski yotyando lwezonyango ifuna isixhobo sovavanyo lokungena kwegazi

I-ISO 22609: 2004 isixhobo sokukhusela i-pathogen eyosulelayo indlela yokuvavanya imaski yonyango yokuchasana nokungena kwegazi elenziweyo (umthamo osisigxina, inaliti ethe tye)

I-ASTM f1862-07 Indlela yoVavanyo oluQhelekileyo lokuNchasa iiMaski zoBuso bezoNyango ukuba zicinywe ngeGazi eliFanelekileyo (Uqikelelo oluthe tyaba lweVolume eFixed kwiVelocity yoLwazi)
