(1) uhlolo lwemihla ngemihla
a. Umhloli, amaxesha kunye neerekhodi
Umqhubi okanye abasebenzi abamiselweyo baya kuhlola inkangeleko rhoqo kwikhonkco lokuphakamisa yonke imihla yokusebenza, kwaye kuya kubakho irekhodi "yohlobo lokuhlolwa kwendawo yemihla ngemihla yesling" (jonga iSihlomelo) kwindawo leyo, ebonisa ukuba isling ingasetyenziswa ngokuqhelekileyo.
b. Ukuhlolwa okubonakalayo
Jonga ngokubonakalayo imbonakalo ukuze ubone iimpawu zokuguguleka okukhulu, ukuguquka okanye umonakalo wangaphandle. Ukuba kufunyenwe iziphene kuhlolo, qinisekisa ukuba ingasetyenziswa kwakhona ngokwendlela yokuhlola eqhelekileyo.
(2) Ukuhlolwa rhoqo
a. Umhloli, amaxesha kunye neerekhodi
Abasebenzi abatyunjiweyo baya kuqhuba uhlolo olupheleleyo kwitsheyini ngokweempawu zesiphene ezicetywayo luhlolo oluqhelekileyo, baze benze iirekhodi zokuvavanya ukuba itsheyini ingaqhubeka nokusetyenziswa na.
b. Amanqaku okujonga
i） Nokuba iimpawu zangaphandle ezifana nophawu lwetyathanga lokuphakamisa kunye nomthwalo wokugqibela wokusebenza zicacile na;
ii) Izihlanganisi eziphezulu nezisezantsi (ikhonkco eliphambili, ikhonkco eliphakathi, izihlanganisi kunye neehoko) zekhonkco lokuphakamisa zikhubazekile, zinqunyulwe kwaye ziqhekekile, ezidlula iimfuno ezisemgangathweni kwaye azinakusetyenziswa;
iii) Ukuguquka kwekhonkco lekhonkco: ikhonkco lekhonkco lijijekile, ligobile kwaye lide, kwaye alinakusetyenziswa xa lidlula iimfuno ezisemgangathweni;
iv) Ukwaphuka kweekhonkco: i-notch, i-notch, i-gouge kunye nokwaphuka kwekhonkco elingaphandle kwecandelo elithe tye akunakusetyenziswa xa kudlule iimfuno ezisemgangathweni;
v) Ukuguqulwa kwehoki: ukuguqulwa "kokuvula" kunye nokugqwethwa kokuvuleka kwehoki kudlula iimfuno ezisemgangathweni kwaye akunakusetyenziswa;
vi) Iintanda: iintanda ezibonakaliswe ngokujonga ngamehlo okanye nge-NDT azinakusetyenziswa.
a. ukuguqulwa:
ubude obungaphandle > 3%
ubude obungaphakathi > 5%
b. ukunxiba:
