Ivugurura ry’amahame mpuzamahanga riyobowe n’Ubushinwa mu bijyanye n’ibyuma byashyizwe ahagaragara ku mugaragaro

Iri hame ryatanzwe kugira ngo rivugururwe mu 2022 mu nama ngarukamwaka ya Komite Nto ya ISO/TC17/SC12 Steel/Continuously Rolled Flat Products, kandi ryatangijwe ku mugaragaro muri Werurwe 2023. Itsinda ry’abakozi ryateguye ryamaze imyaka ibiri n’igice, aho inama imwe y’itsinda ry’abakozi n’inama ebyiri ngarukamwaka zabereye mu biganiro bikomeye, kandi muri Mata 2025, icyiciro cya gatandatu cy’ivugururwa rya ISO 4997:2025 “Structural Grade Cold Rolled Carbon Thin Steel Plate” cyatangijwe.

Iri hame ni irindi vugurura mpuzamahanga ryayobowe n'Ubushinwa nyuma y'uko Ubushinwa bufashe umwanya wa Perezida wa ISO/TC17/SC12. Ishyirwa ahagaragara rya ISO 4997:2025 ni irindi terambere mu kwitabira k'Ubushinwa mu mirimo mpuzamahanga yo gupima ibyuma n'imirongo nyuma ya ISO 8353:2024.

Ibikoresho by'icyuma gikonje cya karuboni n'ibicuruzwa byashyizwe mu cyuma gikonjeshwa n'icyuma cya carbon byihaye intego yo kunoza imbaraga no kugabanya ubugari, bityo bikagabanya uburemere bw'ibicuruzwa, kugera ku ntego nyamukuru yo kuzigama ingufu no kugabanya imyuka ihumanya, no kugera ku gitekerezo cy'umusaruro w'icyuma "icyatsi kibisi". Verisiyo yo mu 2015 y'ihame ry'imbaraga z'umusaruro zikoreshwa cyane ku isoko rya 280MPa ntabwo yagenwe. Byongeye kandi, ibikubiye mu ihame, nko gukaraba kw'ubuso n'uburemere bw'itsinda, ntibihura n'ibikenewe by'umusaruro ugezweho. Kugira ngo hongerwe uburyo iri tegeko rikoreshwa, Ikigo cy'Ubushakashatsi ku Mabwiriza y'Inganda z'Ibyuma cyashyizeho Anshan Iron & Steel Co. gusaba umushinga mushya mpuzamahanga w'akazi kuri iki gicuruzwa. Mu ivugurura, ibisabwa mu ikoranabuhanga ku rwego rushya byagenwe nyuma yo kugisha inama impuguke zo mu Buyapani, mu Budage no mu Bwongereza inshuro nyinshi, bihatira kuzuza ibisabwa mu gukora no kugenzura muri buri gihugu no kwagura uburyo bwo gushyira mu bikorwa ibipimo ngenderwaho. Ishyirwa ahagaragara rya ISO 4997:2025 “Structural Grade Cold-Rolled Carbon Thin Steel Plate” rishyira amanota n’amahame mashya yakozweho ubushakashatsi n’iterambere n’Ubushinwa ku isi.
