- Ikizamini cyo kugorora kugira ngo harebwe ubushobozi bw'umuyoboro bwo kwihanganira guhindagurika
- Ikizamini cyo kunama kw'imizi (imashini zikoreshwa mu gusukamo amazi) kugira ngo umuyoboro urusheho koroha kandi ugire ubuziranenge.
- Ikizamini cya Hydrostatic kugira ngo hamenyekane ko umuyoboro utonyanga neza

16. Imiterere y'ibyo umuntu asabwa gutanga:
- Nkuko byazinguruwe
- Byasanzwe
- Izungurutse bisanzwe
17. Ikimenyetso:
- Buri muyoboro ugomba kuba wanditseho amakuru akurikira neza:
- Izina cyangwa ikirango cy'umukora
- SANS 719 Icyiciro cya C
- Ingano (umurambararo wo hanze n'ubugari bw'urukuta)
- Umubare w'ubushyuhe cyangwa umubare w'itsinda
- Itariki yakoreweho
- Ibisobanuro birambuye ku cyemezo cy'igenzura n'ikizamini
18. Ibisabwa byihariye:
- Imiyoboro ishobora guhabwa irangi cyangwa imitako yihariye kugira ngo ikoreshwe mu buryo bwihariye (urugero, irangi rya epoxy ririnda ingese).
19. Ibizamini by'inyongera (Niba bikenewe):
- Ikizamini cy'ingaruka za Charpy V-notch
- Ikizamini cy'ubukomere
- Isuzuma ry'imiterere migari
- Isuzuma ry'imiterere y'uturemangingo
20. Kwihanganirana:
-Umurambararo wo hanze
-Ubugari bw'urukuta
Ubunini bw'urukuta rw'umuyoboro, nubwo bwaba buri hagati ya +10% cyangwa -8%, bugomba kuba bumwe mu gaciro katanzwe mu nkingi kuva kuri 3 kugeza kuri 6 z'imbonerahamwe iri hepfo, keretse iyo ubwumvikane hagati y'uwakoze n'uwaguze.
-Kugororoka
Gutandukana kw'umuyoboro uvuye ku murongo ugororotse ntibigomba kurenza 0.2% by'uburebure bw'umuyoboro.
Ubusembwa ubwo aribwo bwose butari buzengurutse (usibye ubwo buterwa no kugwa), bw'imiyoboro y'inyuma irenga mm 500 ntibugomba kurenza 1% by'umurambararo w'inyuma (ni ukuvuga uburebure ntarengwa bwa 2%) cyangwa mm 6, icyo ari cyo cyose kiri munsi yayo.
Menya ko uru rupapuro rw'amakuru arambuye rutanga amakuru arambuye yerekeyeImiyoboro ya SANS 719 Grade CIbisabwa byihariye bishobora gutandukana bitewe n'umushinga n'ibipimo nyabyo by'umuyoboro ukenewe.
