Ukwethulwa komhloli we-mask synthetic wokungena kwegazi ISO 22609-2004

Izici eziyinhloko zokuhlola ukungena kwegazi kwemaski yezokwelapha:

1. Idivayisi yokulungisa isampula egqagqene ingalingisa isimo sangempela sokusetshenziswa kwemaski, ishiye indawo eqondiswe kuyo ukuhlolwa, futhi ingalimazi isampula, futhi yenze igazi lokwenziwa lisabalaliswe endaweni eqondiwe yesampula.

2. Isisetshenziswa esikhethekile somjovo ongaguquki singafafaza umthamo othile wegazi lokwenziwa ngesikhathi esilawulwayo.

3, ingakwazi ukulingisa ngokugcwele umfutho wegazi ojwayelekile womzimba womuntu ongu-10.6kPa, 16kPa, 21.3kPa ohambisana nesivinini sejethi ukuze enze ukuhlolwa.

4, ipuleti eliqondiwe elingaguquki, lingavimba umfutho ophezulu engxenyeni yokugeleza koketshezi lwe-jet, vumela kuphela ingxenye yejethi egelezayo iye kusampula, ikhulise ukunemba nokuphindaphinda kwejubane loketshezi lwejethi kusampula.

Isihloli sokungena kwegazi sokwenziwa kwemaski sihlangabezana namazinga:

I-GB 19083-2010 Izidingo zobuchwepheshe zamamaski okuvikela ezokwelapha, ukusebenza kwesithiyo sokungena kwegazi sokwenziwa esingu-5.5

Indlela yokuhlola yokungena kwegazi lokwenziwa ngamamaski ezokwelapha ukuze kuvikelwe Amagciwane Athathelwanayo (Ivolumu engashintshi, Ijethi Evundlile)

YY 0469-2011 Amamaski okuhlinzwa adinga okokusebenza kokuhlola ukungena kwegazi

I-TS EN ISO 22609-2004 Imaski yezokwelapha ukuze uvikeleke kumagciwane athathelwanayo - Indlela yokuhlola ukumelana nokungena kwegazi okokwenziwa (Ivolumu engaguquki, iJet evundlile)

I-ASTM F1862-07 Indlela Yokuhlola Ejwayelekile Yokumelana Nemaski Obuso Bezokwelapha Ekungeneni Ngegazi Lokwenziwa (Ukuqagela Okuvundlile Kwevolumu Egxilile Ngesivinini Sokwazi)
