I-GB/T 6728-2025 ithatha indawo yohlelo luka-2017 lwezingxenye ezingenalutho ezakhiwe ngendlela ebandayo eShayina, yethula izidingo ezibuyekeziwe zokwenziwa, ukulawulwa kwekhwalithi, kanye nokuhambisana nezindinganiso.
Amaphrojekthi aphesheya adinga ukuhlolwa kokulingana kwezinto ezibonakalayo nezindinganiso ezisetshenziswa kabanzi njenge-EN 10219 kanye ne-ASTM A500. Lo mhlahlandlela unikeza idatha yokubhekisela yobunjiniyela engalandwa, ukuqhathanisa ibanga lensimbi, kanye nezilinganiso zokuhlola ubuchwepheshe.
· Imibhalo Yezinkomba Zobunjiniyela
Ukuze kube lula ukubuyekezwa kokuhambisana nobuchwepheshe kanye nokuhlolwa komklamo, indinganiso esemthethweni yensimbi yesakhiwo iyatholakala ukuze ihlolwe ubunjiniyela ezinhlotsheni eziningi zezilimi:
