Inxalenye yokuhluza imaski yesiqingatha (8228-2 FFP2)
Ukuqulunqwa kwezinto
Umaleko ongaphezulu yi-45g yelaphu elingalukwanga.Uluhlu lwesibini luyi-45g FFP2 izinto zokucoca.Umaleko ongaphakathi yi-220g ye-acupuncture cotton.
Imaski ehluza isiqingatha yesuntswana ibufanele ubuso kwaye iyilelwe ukukhusela umntu ozinxibileyo izingcolisi ezinobungozi emoyeni.Banikezela ngokulinganisela kokuhluza kunye nokuphefumla.Ezi maski zineentsinga eziphotheneyo zokucoca iintsholongwane ezisemoyeni, kwaye zingena kufutshane nobuso.Imiphetho yenza itywina elilungileyo emlonyeni nasempumlweni.
Uvavanyo olufanelekileyo yenye yeendlela zokuvavanya imaski.
Uvavanyo olufanelekileyo
Uvavanyo lokufaneleka kwesiphefumlo luyenziwa ukufumanisa ukuba isiphefumlo sibungena kakuhle kangakanani na ubuso bomntu osinxibileyo okanye ukuvuza kwangaphakathi kwamasuntswana.Kuvavanyo lwe-quantitative fit, indlela eqhelekileyo kukulinganisa ugxininiso lwenombolo yesuntswana ngaphakathi nangaphandle kwendawo yokuphefumla ngelixa umntu onxibileyo esenza uthotho lwemithambo;ngokufuthi isodiyam chloride okanye amanye amasuntswana akhululwa ngaphandle isiphefumlo ukuqinisekisa ukuba amasuntswana quantifiable ukugqobhoza ukungena facepiece.Ukulungelelaniswa kwendawo yokuphefumla kuchazwa yinto efanelekileyo, umlinganiselo woxinaniso lwamasuntswana angaphandle kwendawo yokuphefumla ukuya kuloo ngaphakathi kwendawo yobuso yesiphefumlo.Uvavanyo olufanelekileyo lulinganisa ukuvuza kwangaphakathi ngokupheleleyo-ukuvuza kweentsinjana ngetywina lobuso, iivalvu, kunye neegaskets, kunye nokungena ngesihluzo.Kwi-EU, into efanelekileyo ihlengahlengiswa ngexesha lokuphefumla kunye nokukhupha umoya ukumisela ukuvuza okupheleleyo kwangaphakathi (EU EN 149 + A1, 2009).Kwi-EU (i-EU EN 149 + A1, 2009) kunye neTshayina (i-China National Standard Standard GB 2626-2006, 2006), iimvavanyo zokuvuza zangaphakathi zizonke ziyafuneka njengenxalenye yenkqubo yesiqinisekiso sokuphefumula.E-USA, uvavanyo lokufaneleka kwesiphefumlo luxanduva lomqeshi, kwaye aluyonxalenye yenkqubo yoqinisekiso lwesiphefumlo.
Yintoni uphawu lweCE?
I-CE luphawu lwesiqinisekiso ngaphakathi kwi-European Union.Iimveliso ezinophawu lwe-CE zihlangabezana nazo zonke iimfuno malunga nempilo, ukhuseleko kunye nokusingqongileyo.I-CE imele i-Conformité Européenne, eguqulelwa ngokuthe ngqo ithetha ngokuhambelana nemigaqo yaseYurophu.
Iimveliso ezinophawu lwe-CE zinokuthengiswa kwaye zisetyenziswe naphi na ngaphakathi kwi-European Economic Area (EEA).Ukumakishwa kwe-CE sisiqinisekiso somvelisi sokuba imaski ihambelana nomthetho wangoku we-EU.
