15. Ukupakisha:
-Eibhanti
-Iicaphu zeplastiki kwiziphelo zombini
-Iphepha lamanzi okanye ikhava yephepha lensimbi
- Ukumakisha: njengoko kufuneka (kubandakanya umvelisi, iBanga, ubungakanani, umgangatho, inombolo ye-SEFRE.)
16. Imeko yokuhambisa:
-Ngqengqeleka
-Iqhelisiwe
-Ngqengqele
17. Ukumakisha:
-Umbhobho ngamnye kufuneka aphawulwe ngokusemthethweni kule ngcaciso ilandelayo:
-Igama lomvelisi okanye uphawu lwentengiso
-I-SANS 719 IBakala C
Ubungakanani (ububanzi bodwa kunye nobubanzi beWall)
-Inombolo ye-shere okanye inombolo ye-batch
-Wahlatho yeMveliso
-Ukuhlolwa kunye neenkcukacha zovavanyo
18. Iimfuno ezizodwa:
-Imibhobho inokubonelelwa ngeengubo ezikhethekileyo okanye izikhonkwane zezicelo ezithile (umz.
19. Uvavanyo olongezelelweyo (ukuba luyafuneka):
- Uvavanyo lwempembelelo ye-charpy v-istch
-Ivavanyo lobunzima
-Imviwo ye-Macrost
-Umviwo kuvavanyo lwamabala
20.UYA:
-Iidayimitha
-Ukuba nobungqingqwa
Ubungqingqwa bodaka bombhobho buya kuthi, buxhomekeke ekunyamezeleni i- nye ye-10% okanye -8%, ibe yenye yamaxabiso afanelekileyo anikezwe kwiikholamu ezi-3 ukuya kwi-6 kwitafile engezantsi, umthengi.
-Ukuzonwabisa
Nakuphi na ukuphambuka kombhobho womqolo othe tye, akuyi kuba ngaphezu kwe-0,2% yobude bombhobho.
Nakuphi na ukujikeleza (ngaphandle kwale nto ibangelwa yi-SAG), imibhobho engaphezulu kwe-500 mm ingabi ngaphezu kwe-500 mm ngaphezulu kwe-1% ye-Ovread 2%) okanye i-6 mm, nokuba yeyiphi na engaphantsi.
Nceda uqaphele ukuba le phepha ledatha eneenkcukacha libonelela ngolwazi olubanzi malungaI-SANS 719 Ibanga C C. Iimfuno ezithile zinokwahluka ngokusekwe kwiprojekthi kunye nenkcazo ngqo yombhobho efunekayo.
