Ezweni lokuhlolwa kwezinto zokwakha, ikakhulukazi upende kanye nezingubo, ukuqonda ukumelana nokuklwebheka kubalulekile. Yilapho imishini yokuhlola ukuklwebheka (eyaziwa nangokuthi imishini yokuhlola ukugqokwa nomaumshini wokuhlola obukhali) zingena. Le mishini iklanyelwe ukuhlola ikhono lento yokumela ukungqubuzana nokuguguleka, okubalulekile ekuqinisekiseni ukuthi imikhiqizo ehlukahlukene ihlala isikhathi eside futhi ihlala isikhathi eside.

I-ASTM (i-American Society for Testing and Materials) ithuthukise amazinga amaningana okuqondisa ukuhlolwa kokuhuzuka. Izindinganiso ezimbili eziphawulekayo yi-ASTM D2486 kanye ne-ASTM D3450, ezigxile ezicini ezahlukene zokuhlolwa kokuhuzuka.

Izindinganiso ze-ASTM ezingase zisebenze kakhulu ekuhlolweni kwakho kokuklwebheka zifaka:

I-ASTM D2486– Lena indinganiso yokuhlola yokulinganisa ukumelana kopende ekugugulekeni okubangelwa ukukhuhla.

I-ASTM D3450– Lena yindlela ejwayelekile yokuhlola izakhiwo zokugezwa kwezingubo zangaphakathi.

I-ASTM D4213– Lena indlela ejwayelekile yokuhlola ukumelana nokukhuhla kwamapende ngokunciphisa isisindo ngokuhuzuka.

I-ASTM D4828– Lena yindlela yokuhlola ejwayelekile yokugeza okusebenzayo kwezimbozo eziphilayo.

I-ASTM F1319– Lena indlela yokuhlola ejwayelekile echaza inqubo yokunquma inani lesithombe esidluliselwe ebusweni bendwangu emhlophe ngokuhlikihla.

I-ASTM D2486 iyindinganiso eyenzelwe ngqo ukukala ukumelana kwezimbozo ekugqwaleni. Lokhu kuhlolwa kubaluleke kakhulu kubakhiqizi bokupenda nokumboza ngoba kulingisa ukuguguleka okwenzeka ezisetshenzisweni zangempela. Ukuhlolwa kuhilela ukufaka ubuso obumboziwe esenzweni sokukhuhla (ngokuvamile ngezinto ezihluphayo ezithile) ukuze kutholakale ikhono lembozo lokumelana nomonakalo. Imiphumela inikeza ukuqonda okubalulekile ngokuqina kwembozo, kusiza abakhiqizi ukuthuthukisa ukwakheka nokuqinisekisa ukuthi imikhiqizo yabo ihlangabezana nokulindelwe ngabathengi.

Ngakolunye uhlangothi, i-ASTM D3450 ibhekana nokugezwa kahle kwezimbozo zezakhiwo zangaphakathi. Leli zinga libalulekile ekuhloleni ukuthi indawo ingahlanzwa kalula kangakanani ngaphandle kokulimaza ingubo. Ukuhlola kuhilela ukusebenzisa ikhambi elithile lokuhlanza nokuhlikihla indawo ukuze kuhlolwe ukumelana kwengubo ekugugulekeni kanye nekhono layo lokugcina ukubukeka kwayo ngokuhamba kwesikhathi. Lokhu kubaluleke kakhulu ngezimbozo ezisetshenziswa ezindaweni ezinabantu abaningi noma ezindaweni ezidinga ukuhlanzwa njalo, njengekhishi nezindlu zangasese.

Kokubili i-ASTM D2486 kanye ne-ASTM D3450 kugcizelela ukubaluleka kokusebenzisa isihloli sokuklwebheka ukuze kwenziwe lokhu kuhlolwa ngokunembile. Le mishini ifakwe izici ezahlukahlukene zokulawula izimo zokuhlola, iqinisekisa imiphumela ethembekile nephindaphindwayo. Ngokusebenzisa i-umshini wokuhlola obukhali, abakhiqizi bangathola ukuqonda okujulile kokusebenza kwemikhiqizo yabo futhi benze izinqumo ezinolwazi mayelana nokulungiswa kokwakheka noma ukuthuthukiswa komkhiqizo.

Ngaphezu kwalezi zindinganiso ze-ASTM, ukusetshenziswa kwezihloli zokuhuzuka akugcini nje ngopende kanye nopende. Izimboni ezifana nezimoto, izindiza, kanye nokwakha nazo zithembele ekuhlolweni kokuhuzuka ukuze zihlole ukuqina kwezinto ezisetshenziswa emikhiqizweni yazo. Isibonelo, le mishini ingasetshenziswa ukuhlola ukusebenza kokuhuzuka okuvikelayo ezimotweni noma ukumelana nokuguguleka kwezinto zokwakha phansi ukuqinisekisa ukuthi ziyahlangabezana nezindinganiso zemboni kanye nezidingo zabathengi.

I-ASTMamazinga okuhlola ukuklwebheka, ikakhulukazi i-ASTM D2486 kanye ne-ASTM D3450, zidlala indima ebalulekile ekuhloleni ukuqina kwamapende kanye nopende. Ukusebenzisa umshini wokuhlola ukuklwebheka kubalulekile ekwenzeni lezi zivivinyo ngempumelelo, kuhlinzekwe abakhiqizi ngemininingwane abayidingayo ukuze bathuthukise imikhiqizo yabo. Njengoba imboni iqhubeka nokubeka phambili ikhwalithi kanye nokuphila isikhathi eside, ukubaluleka kokuhlolwa kokuklwebheka kuzokwanda kuphela, okwenza lezi zindinganiso kanye nemishini yokuhlola ibe ngamathuluzi abalulekile kwisayensi yezinto zokwakha kanye nobunjiniyela.
