Cermet icyuma ntigikeneye gusa gukomera no gukomera cyane nkibikoresho fatizo, ahubwo inashyira mubikorwa byimazeyo ibipimo ngenderwaho bijyanye nuburyo bukurikira bwo kubyara umusaruro wo gusya inshuro ebyiri, gusya ahantu hamwe no gutambuka ku nkombe, kugirango bitange ubumenyi kandi buhanitse- ibicuruzwa byiza.ibicuruzwa.
Twese tuzi ko urwego rwukuri rwicyuma rushobora kumenyekana uhereye ku cyitegererezo cya ISO, none rero uyu munsi tuzabanza kumenyekanisha ibirimo bijyanye nukuri kurwego rwa ISO ihinduka.
Kurugero, icyitegererezo cyicyuma cyavuzwe haruguru ni TPGH110304L10PK C3
Inyuguti ya gatatu G isobanura neza, ni ugusya-urwego rusobanutse kurambirana.
