Inqaku 5.2.2 lomgangatho we-ASTM F1740-96(2007) libonisa ukuba ubomi benkonzo ende kakhulu yentambo yiminyaka eyi-10.IKomiti ye-ASTM icebisa ukuba intambo yokhuseleko kufuneka itshintshwe nokuba ayizange isetyenziswe emva kweminyaka elishumi yokugcina.
Xa sikhupha intambo yokhuseleko ukuze sisebenze ngokubonakalayo kwaye siyisebenzise kwiimeko ezimdaka, ezinelanga kunye nemvula, ukuze ikwazi ukubaleka ngokukhawuleza kwiipuli, iintambo zokuxhuzula kunye nokuhla ngokukhawuleza, ziya kuba yintoni iziphumo zolu setyenziso?Intambo yilaphu.Ukugoba, ukugquma, ukusetyenziswa kwindawo erhabaxa kunye nomjikelo wokulayisha/wokothula konke kuya kubangela ukunxitywa kwefayibha, ngaloo ndlela kucuthwe amandla okusebenzisa intambo.Nangona kunjalo, akucaci ukuba kutheni i-micro-ukulimala kweentambo iya kuqokelelana kwi-macro-damage, kwaye isizathu sokuba amandla okusebenzisa iintambo ngokucacileyo ancitshisiwe.
UBruce Smith, umbhali-mbhali we-On Rope, waqokelela waza waqhekeza iintambo zesampulu ezingaphezu kwe-100 zokuhlola umqolomba.Ngokusetyenziswa kweentambo, iisampulu zihlelwa "njengentsha", "ukusetyenziswa okuqhelekileyo" okanye "ukuxhatshazwa".Iintambo “ezintsha” zilahlekelwa yi-1.5% ukuya kwi-2% yamandla minyaka le ngokwe-avareji, ngelixa iintambo “zokusetyenziswa ngokuqhelekileyo” zilahlekelwa yi-3% ukuya kwi-4% yamandla minyaka le.USmith ugqibe kwelokuba "ukugcinwa kakuhle kweentambo kubaluleke kakhulu kunobomi benkonzo yeentambo."Mingaphi iminyaka intambo yokhuseleko ichithiweyo?
Uvavanyo lukaSmith lungqina ukuba xa lusetyenziswa kancinci, intambo yokuhlangula ilahlekelwa yi-1.5% ukuya kwi-2% yamandla minyaka le ngokomndilili.Xa isetyenziswa rhoqo, ilahlekelwa yi-3% ukuya kwi-5% yamandla minyaka yonke ngokomndilili.Olu lwazi lunokukunceda ukuba uqikelele ilahleko yamandla entambo oyisebenzisayo, kodwa ayinakukuxelela ngokuthe ngqo ukuba kufuneka ucime intambo.Nangona unokuqikelela ilahleko yamandla entambo, kufuneka ukwazi kwakhona ukuba yintoni ilahleko yamandla evumelekileyo phambi kokuba intsontelo isuswe.Ukusukela namhlanje, akukho mgangatho unokusixelela ukuba yomelele kangakanani na intambo yokhuseleko esetyenzisiweyo.
Ukongeza kokuphulukana nobomi beshelufu namandla, esinye isizathu sokuphelisa iintambo kukuba iintambo zonakele okanye iintambo ziye zonakaliswa ngendlela ekrokrisayo.Ukuhlolwa kwangethuba kunokufumanisa umonakalo, kwaye amalungu eqela anokunika ingxelo kwangethuba ukuba intambo ibethwe ngumthwalo wempembelelo, ibethwe ngamatye okanye umhlaba phakathi kwe-stretcher kunye nodonga.Ukuba uthatha isigqibo sokuphelisa intambo, yihlukanise kwaye ujonge ngaphakathi kwendawo eyonakalisiweyo, ukuze ukwazi ngakumbi malunga nobungakanani besikhumba sentambo sonakaliswe kwaye singakwazi ukukhusela intambo yentambo.Kwiimeko ezininzi, undoqo wentambo awusayi konakaliswa.
Kwakhona, ukuba uyathandabuza malunga nokuthembeka kwentambo yokhuseleko, yisuse.Iindleko zokutshintshwa kwezixhobo azibizi ngokwaneleyo ukubeka ubomi babahlanguli emngciphekweni.
