Ukudla okusemathinini okune-asidi ephansi kubhekisela ekudleni okusemathinini okunenani le-PH elingaphezu kuka-4.6 kanye nomsebenzi wamanzi ongaphezu kuka-0.85 ngemva kokuba okuqukethwe kufinyelele ekulinganeni. Imikhiqizo enjalo kumele ihlanzwe ngendlela enenani lokuhlanza elingaphezu kuka-4.0, njengokuhlanza okushisa, izinga lokushisa ngokuvamile lidinga ukuhlanza ekushiseni okuphezulu kanye nokucindezela okuphezulu (kanye nokushisa okuhlala njalo isikhathi esithile) ngaphezu kuka-100 °C. Ukudla okusemathinini okunenani le-pH elingaphansi kuka-4.6 kungukudla okusemathinini okune-asidi. Uma kuhlanza ngokushisa, izinga lokushisa ngokuvamile lidinga ukufinyelela ku-100 °C ethangini lamanzi. Uma i-monomer esemathinini ingagoqwa ngesikhathi sokuhlanza, izinga lokushisa lamanzi lingaba ngaphansi kuka-100 °C, futhi kusetshenziswa lokho okubizwa ngokuthi izinga lokushisa eliphansi. Indlela yokuhlanza eqhubekayo. Amapentshisi avamile asemathinini, ama-citrus asemathinini, amaphayinaphu asemathinini, njll. angokudla okusemathinini okune-asidi, futhi zonke izinhlobo zezilwane ezisemathinini, izinkukhu, imikhiqizo yasemanzini kanye nemifino esemathinini (njengobhontshisi oluhlaza osemathinini, ubhontshisi obanzi osemathinini, njll.) angokudla okusemathinini okune-asidi ephansi. Amazwe amaningi nezifunda emhlabeni wonke anezindinganiso noma imithethonqubo yokucaciswa kokukhiqizwa kokudla okusemathinini. Ngo-2007, izwe lami lakhipha i-GB/T20938 2007 ethi "Umkhuba Omuhle Wokudla Okusemathinini", echaza imigomo nezincazelo zamabhizinisi okudla okusemathinini, indawo yefektri, indawo yokusebenzela kanye nezindawo, imishini namathuluzi, ukuphathwa kwabasebenzi nokuqeqeshwa, ukulawulwa kwezinto ezibonakalayo nokuphathwa kwazo, ukulawulwa kwenqubo yokucubungula, ukuphathwa kwekhwalithi, ukuphathwa kwenhlanzeko, ukugcinwa nokuthutha komkhiqizo oqediwe, imibhalo namarekhodi, ukuphathwa kwezikhalazo kanye nokukhunjulwa komkhiqizo. Ngaphezu kwalokho, izidingo zobuchwepheshe zesistimu yokubulala amagciwane yokudla okusemathinini okune-asidi ephansi zichazwe ngokukhethekile.
