Intego y'ibanze ya gupima umunyu no kwirinda amazi yanduye kuriUMUYOBORO WA SMLGusiga muri EN877 ni ugusuzuma uburyo igitambaro kirwanya ingese mu buryo burambye (aside, alkali, umunyu), ingese zikomoka ku mashanyarazi, na mikorobe hakoreshejwe kwigana ibidukikije bikomeye kandi bihumanya (amazi y’imyunyu ngugu n’amazi mabi y’ibinyabutabire/ibinyabuzima).Iri suzuma rigaragaza ubushobozi bw'igitambaro cyo kurinda neza icyuma gikozwe mu cyuma cyashongeshejwe kwangirika mu gihe cyose cy'igishushanyo cy'umuyoboro. Ibi byemeza ko igitambaro gikomeza kuba cyiza kandi gifatana neza nyuma yo gukoreshwa igihe kirekire.
Isuzuma mu buryo butaziguye ubushobozi bw'igitambaro cyo kubungabunga urukuta rw'imbere rw'umuyoboro no kwemeza ko amazi asohoka neza. Iri suzuma rigira uruhare runini mu kugenzura ubuziranenge bw'ibicuruzwa no kubona icyemezo gisanzwe.
Ubudahangarwa bwo gusukurwa n'umunyu
Ibizamini bigomba gukorwa hakurikijwe EN IS0 9227 kandi nyuma y’igihe cy’ikizamini nibura amasaha 350, ingero zigomba kozwa n’amazi adasukuye kugira ngo haveho ibisigazwa by’umunyu. Hanyuma, ibisigazwa bigomba gusuzumwa ako kanya kugira ngo harebwe ko hari uduheri cyangwa ingese.
Uburyo bwo gupima:Ikizamini cyo gutera umunyu gikoresha umuti udafite umunyu udasanzweUmuti wa NaCl wa 5% mu masaha 350Nyuma y'igihe cyo gukora ikizamini kirangiye, oza n'amazi adafite umunyu kugira ngo ukureho umunyu usigaye, hanyuma uhitegenzura imbere mu gipfundikizo kugira ngo urebe niba hari ingese n'imyoboUrwego rw'umwobo w'ingufu ntirurenga Icyiciro cya 3, nk'uko bivugwa muri ISO 4628-2, kandi urwego rw'ingufu ntirurenga Icyiciro cya 2, nk'uko bivugwa muri ISO 4628-3.
Ingano y'umwobo w'umucanga: Icyiciro cya 3 cyangwa hejuru nk'uko byavuzwe muri ISO4628-2; Ingano y'ingufu: Icyiciro cya 2 cyangwa hejuru nk'uko byavuzwe muri ISO4628-3
Ubudahangarwa ku mazi yanduye
Ingero zigomba kwinjizwa mu mazi kugira ngo30d mu mazi yanduye ku bushyuhe bwa (23 + 3)°Chamwe n'imiterere yatanzwe mu mbonerahamwe ya 8.
Uburyo bwo gupima:Igihe cyo kwibiza mu mazi kirangiye, ingero zigomba kozwa n'amazi adafunguye hanyuma zikamishwa. Zigomba guhita zisuzumwa kugira ngo zirebe niba zarangiritse cyangwa zangiritse. Nyuma yoAmasaha 24 ku bushyuhe bw'ikirere bwa (23±3)°Cingero zigomba kongera gusuzumwa.
Nta gutakaza uburyo bwo gufatana cyangwa ingese byemerwa.
