(Ubushinwa) YYP116-2 Igipimo cy’Ubusugire bw’Ikinyakanada (Canadian Standard Freeness Testing)
Igipimo cy’Ubusugire bw’Ibintu mu gihugu cya Kanada gikoreshwa mu kumenya igipimo cyo kuyungurura amazi mu bisigazwa by’amazi bitandukanye, kandi kigaragazwa n’igitekerezo cy’ubusugire bw’ibintu (CSF). Igipimo cyo kuyungurura kigaragaza uko insinga zimeze nyuma yo gusya cyangwa gusya neza. Igikoresho gisanzwe cyo gupima ubusugire bw’ibintu gikoreshwa cyane mu gikorwa cyo gusya mu nganda zikora impapuro, gushyiraho ikoranabuhanga ryo gukora impapuro n’igerageza ritandukanye ryo gusya ry’ibigo by’ubushakashatsi bya siyansi.
Ni igikoresho cy'ingenzi cyo gupima mu gucukura no gukora impapuro. Iki gikoresho gitanga agaciro k'igerageza gakwiriye mu kugenzura umusaruro w'udusimba tw'ibiti byashongeshejwe. Gishobora kandi gukoreshwa cyane mu guhindura amazi mu gucukura ibinyabutabire bitandukanye mu gihe cyo gukubita no gutunganya. Kigaragaza imiterere y'ubuso bw'udusimba n'imiterere y'ubwivumbure.
Ubusugire bw’ibipimo bya Kanada bivuga ko hakurikijwe amabwiriza yashyizweho, hakoreshejwe uburyo bwo gupima imikorere y’amazi yo mu mazi ya 1000 mL, ingano yayo ikaba (0.3 + 0.0005) %, ubushyuhe bukaba 20 °C, ingano (mL) y’amazi asohoka mu muyoboro wo ku ruhande rw’igikoresho bivuze agaciro ka CFS. Igikoresho gikozwe mu byuma bidashonga, kandi kimara igihe kirekire.
Igipimo cy’ubudahangarwa kigizwe n’icyumba cyo kuyungurura n’umuyoboro wo gupima ugenda uhuza neza, ugashyirwa ku gice gihamye. Icyumba cyo kuyungurura amazi gikozwe mu cyuma kitagira umugozi. Munsi ya silinda, hari isahani y’icyuma kitagira umugozi n’igipfundikizo cyo hasi gifunga umwuka, gifatanye n’ikibabi cya Loose-leaf ku ruhande rumwe rw’umwobo uzengurutse kandi gifatanye neza ku rundi ruhande. Umupfundikizo wo hejuru urafunze, iyo ufunguye umupfundikizo wo hasi, impumuro y’amazi irasohoka.
Silinda n'umuyoboro w'icyuma ufata icyuma bishyigikiwe n'udupira tubiri tw'icyuma dukozwe mu buryo bwa mashini ku gice cy'icyuma.
