I-International Organisation for Standardization (ISO) iyi-ejensi enkulu kunazo zonke emhlabeni engeyona ekahulumeni ekhethekile yokulinganisa amazinga futhi iyinhlangano ebaluleke kakhulu emkhakheni wokulinganisa amazinga ngamazwe. Umgomo we-ISO ukukhuthaza ukulinganisa kanye nemisebenzi ehlobene nayo emhlabeni wonke, ukuze kube lula ukushintshana kwemikhiqizo nezinsizakalo emhlabeni wonke, kanye nokuthuthukisa ukubambisana kwamazwe ngamazwe olwazini, isayensi, ubuchwepheshe kanye nemisebenzi yezomnotho. Phakathi kwazo, imikhiqizo yokudla ye-ISO/TC34 (ukudla), ukupakishwa kwe-ISO/TC122 (ukupakishwa) kanye nezitsha zensimbi ze-ISO/TC52 Light gauge (izitsha zensimbi ezigoqwe ngodonga oluncane) amakomidi amathathu obuchwepheshe bokulinganisa amazinga afaka amazinga omhlaba wonke ahlobene nokuhlolwa kwekhwalithi yokudla okusemathinini kanye nokupakishwa. Izindinganiso ezifanele yilezi: 1SO/TR11761:1992 “Ukuhlukaniswa kosayizi wethini lamathini ayindilinga anezikhala eziphezulu ezitsheni zensimbi ezinodonga oluncane ngokohlobo lwesakhiwo”, ISO/TR11762:1992 “Amathini ayindilinga avulekayo phezulu ezitsheni zensimbi ezinodonga oluncane ezinemikhiqizo yoketshezi oluphefumulayo ngokohlobo lwesakhiwo Ukuhlukaniswa kosayizi wethini ngohlobo” ISO/TR11776:1992 “Ukudla okusemathinini okunomthamo olinganiselwe wamathini avulekile angewona ayindilinga ezitsheni zensimbi ezinodonga oluncane” IsO1842:1991 “Ukunqunywa kwenani le-pH lemikhiqizo yezithelo nemifino”, njll.
