Izindinganiso zokushelela zezicathulo zokuphepha (izicathulo zokuphepha zabasebenzi)
Ngokusho kwesinyathelo se-cen/tc161, imishini yokuzivikela yomuntu siqu, imishini yokuphepha (iso/tc94) kanye ne-SC3 ziyavumelana ngokuhlanganyela ukuthi: indinganiso ye Izicathulo Zokuphepha Kwimishini yokuzivikela yomuntu siqu, i-EN ISO 20345:2004, indlela yokuhlola evimbela ukushelela isebenzisa indinganiso ye-ISO 13287:2006, kanti inombolo ejwayelekile yokuqala iguqulwe yaba yi-EN ISO 20345:2004/a1:2007. Isimo sokuhlola okushelelayo kuleli zinga ukuhlolwa okushelelayo phakathi kokuhlangana kwesisombululo se-sodium dodecyl sulfate kanye nokuhlangana kwe-glycerol kwepuleti lensimbi. Eyokuqala ingamakwa njenge-SRA lapho ukuhlolwa kudlula, kanti eyesibili ingamakwa ngokusebenzisa ukuhlolwa. Ku-SRB, zombili izivivinyo zingamakwa njenge-Src.
Indinganiso ebuyekeziwe iyalela izivivinyo ezimbili ezibalulekile zelebhu ukuhlola ukusebenza kwezicathulo. Eyokuqala ilingisa izindawo eziphansi zokungqubuzana kusetshenziswa isisombululo se-sodium dodecyl sulfate—i-surfactant evamile etholakala kubahlanzi bezimboni—ukuze imele izindawo ezibushelelezi, ezingcoliswe insipho. Izicathulo ezidlula lolu vivinyo zithola isigaba se-SRA. Ukuhlolwa kwesibili kusebenzisa ipuleti lensimbi elimbozwe nge-glycerol ukuphindaphinda izingozi ezifana nokuchitheka kwamafutha noma amafutha; amamodeli anqoba le nselele athola isitifiketi se-SRB. Imikhiqizo eyanelisa kokubili ukuhlolwa okuqinile ifinyelela isilinganiso se-SRC esiphezulu, okubonisa ukumelana okuphelele kokushelela kuzo zonke izimo eziyingozi ezahlukahlukene.
Lokhu kulungiswa kwezindinganiso kulungisa igebe elibalulekile ekuphepheni emsebenzini. Izehlakalo zokushelela nokuwa zihlala ziyimbangela ehamba phambili yokulimala kwezimboni, ikakhulukazi emikhakheni efana nokwakha, ukukhiqiza, kanye nokucubungula ukudla lapho izindawo zivame ukudalulwa khona oketshezini noma ezintweni zokugcoba. Ngokudinga ukuhlolwa okuqondile nokuphindaphindekayo ngaphansi kwezimo ezilawulwayo, uhlaka olusha luqinisekisa Izicathulo Zokuphepha inikeza ukubamba okuthembekile lapho abasebenzi behamba ezindaweni ezinobungozi obukhulu. Abakhiqizi manje kumele baklame izithende zangaphandle ezigcina zibambekile ezindaweni ezimanzi eziphathwe ngamakhemikhali kanye nezindawo ezinamafutha eziqinile—intuthuko ebalulekile kwezobuchwepheshe kusukela ekuhlolweni kwangaphambilini kwesimo esisodwa.
Uhlelo lokulebula lwe-SRA/SRB/SRC luvumela abaqashi ukuthi bakhethe izicathulo ezenzelwe izingozi ezithile zomsebenzi, kuyilapho abasebenzi bethola ukubonakala okucacile ngamakhono okuvikela. Njengoba izintambo zokuhlinzeka zomhlaba wonke zamukela lezi zindinganiso ezihlangene, kulindeleke ukuthi ukuhambisana kwamazwe ngamazwe ekulandeleni ukuphepha kuqine, kukhuthaze imikhuba yezimboni ephephile emhlabeni jikelele.
