Emhlabeni wokuhlolwa kwezinto zokwakha, ikakhulukazi ama-coatings nopende, ukuqonda ukumelana nemihuzuko kubalulekile. Yilapho imishini yokuhlola ukuhuzuka (eyaziwa nangokuthi imishini yokuhlola ukugqokwa nomaumshini wokuhlola i-abrasive) ngena. Le mishini iklanyelwe ukuhlola ikhono lempahla lokukwazi ukumelana nokungqubuzana nokuguga, okubalulekile ekuqinisekiseni ukuphila isikhathi eside nokuqina kwemikhiqizo ehlukahlukene.

I-ASTM (Inhlangano YaseMelika Yokuhlola Nezinto Zokusebenza) ithuthukise izindinganiso ezimbalwa zokuqondisa ukuhlolwa kokuhuzuka. Izindinganiso ezimbili eziphawulekayo i-ASTM D2486 ne-ASTM D3450, egxile ezicini ezihlukene zokuhlolwa kokuhuzuka.

Amazinga e-ASTM okungenzeka asebenze kakhulu ekuhlolweni kwakho kokuhuzuka ahlanganisa:

I-ASTM D2486– Leli izinga lokuhlola lokulinganisa ukumelana kukapende nokuguguleka okubangelwa ukukhuhla.

I-ASTM D3450- Lena indlela ejwayelekile yokuhlola izakhiwo eziwashekayo zezingubo zezakhiwo zangaphakathi.

I-ASTM D4213- Lena indlela ejwayelekile yokuhlola ukumelana nokukhuhla kopende ngokuncipha kwesisindo somhuzuko.

I-ASTM D4828- Lena indlela yokuhlola emisiwe yokugezeka okusebenzayo kwezingubo zemvelo.

I-ASTM F1319– Lena indlela yokuhlola ejwayelekile echaza inqubo yokunquma inani lesithombe esidluliswa phezu kwendwangu emhlophe ngokuhlikihla.

I-ASTM D2486 iyindinganiso eyenzelwe ngqo ukukala ukumelana kwezingubo zokukhuhla ukugqwala. Lokhu kuhlola kubaluleke kakhulu ekupendeni nasekufakeni abakhiqizi ngoba kulingisa ukuguga okwenzeka ezinhlelweni zomhlaba wangempela. Ukuhlola kuhilela ukufaka indawo eboshiwe esenzweni sokukhuhla (imvamisa ngento egqamile ecacisiwe) ukuze kunqunywe amandla okunamathela okumelana nomonakalo. Imiphumela inikeza imininingwane ebalulekile ngokuqina kwe-coating, isiza abakhiqizi bathuthukise ukwakheka nokuqinisekisa ukuthi imikhiqizo yabo ihlangabezana nokulindelwe ngabathengi.

Ngakolunye uhlangothi, i-ASTM D3450, iphathelene nokugezeka kwezingubo zezakhiwo zangaphakathi. Leli zinga libalulekile ekuhloleni ukuthi indawo engaphezulu ingahlanzwa kalula kanjani ngaphandle kokulimaza ukunamathela. Ukuhlola kuhilela ukusebenzisa isixazululo esithile sokuhlanza nokukhuhla indawo engaphezulu ukuze kuhlolwe ukumelana kwento enamathelayo ekuhutsheni kanye nekhono layo lokulondoloza ukubukeka kwayo ngokuhamba kwesikhathi. Lokhu kubaluleke kakhulu ezimbotsheni ezisetshenziswa ezindaweni ezinabantu abaningi noma ezindaweni ezidinga ukuhlanzwa njalo, njengamakhishi nezindlu zokugeza.

Kokubili i-ASTM D2486 ne-ASTM D3450 zigcizelela ukubaluleka kokusebenzisa umhloli wokuhuzuka ukuze kwenziwe lokhu kuhlolwa ngokunembile. Le mishini ifakwe izici ezihlukahlukene zokulawula izimo zokuhlola, iqinisekisa imiphumela ethembekile nephindaphindwayo. Ngokusebenzisa iumshini wokuhlola i-abrasive, abakhiqizi bangathola ukuqonda okujulile kokusebenza kwemikhiqizo yabo futhi benze izinqumo ezinolwazi mayelana nokulungiswa kokwakhiwa noma ukuthuthukiswa komkhiqizo.

Ngokungeziwe kulawa mazinga e-ASTM, ukusetshenziswa kwezihloli ze-abrasion akukhawulelwe kumapende nama-coatings. Izimboni ezifana nezezimoto, i-aerospace, nezokwakha nazo zithembele ekuhlolweni kokuhuzuka ukuze zihlole ukuqina kwezinto ezisetshenziswa emikhiqizweni yazo. Isibonelo, le mishini ingasetshenziselwa ukuhlola ukusebenza kwezingubo zokuzivikela ezimotweni noma ukumelana nokugqokwa kwezinto ezifakwa phansi ukuze kuqinisekiswe ukuthi zihlangabezana namazinga emboni kanye nezidingo zabathengi.

I-ASTMamazinga okuhlola umhuzuko, ikakhulukazi i-ASTM D2486 kanye ne-ASTM D3450, zidlala indima ebalulekile ekuhloleni ukuqina kwamapende namajazi. Ukusebenzisa umshini wokuhlola imihuzuko kubalulekile ekwenzeni lezi zivivinyo ngendlela efanele, ukunikeza abakhiqizi idatha abayidingayo ukuze bathuthukise imikhiqizo yabo. Njengoba imboni iqhubeka nokubeka phambili ikhwalithi nokuphila isikhathi eside, ukubaluleka kokuhlolwa kwemihuzuko kuzokhula kuphela, okwenza lawa mazinga nemishini yokuhlola abe amathuluzi abalulekile kusayensi yezinto zokwakha nobunjiniyela.
