Ubushinwa buyobowe n’ivugurura ry’ibipimo mpuzamahanga mu bijyanye n’ibyuma n’ibyapa byatangajwe ku mugaragaro

Ibipimo byasabwe gusubirwamo mu 2022 mu nama ngarukamwaka ya ISO / TC17 / SC12 Steel / Gukomeza kuzunguruka ibicuruzwa bya Flat Products Sub-Komite, kandi byatangijwe ku mugaragaro muri Werurwe 2023. Itsinda ry’imirimo yateguye ryamaze imyaka ibiri nigice, aho inama y’itsinda rimwe n’inama ebyiri ngarukamwaka byakozwe mu biganiro bikomeye ISO 4997: Isahani ”yatangijwe.

Iri hame ni irindi vugurura mpuzamahanga riyobowe n'Ubushinwa nyuma yuko Ubushinwa butangiye kuyobora ISO / TC17 / SC12. Isohora rya ISO 4997: 2025 ni iyindi ntera mu Bushinwa mu bikorwa by’ubuziranenge mpuzamahanga mu bijyanye n’ibyuma n’ibyuma nyuma ya ISO 8353: 2024.

Ibyuma bya karubone byubakishijwe icyuma gikonjesha icyuma n’ibicuruzwa byiyemeje kongera imbaraga no kugabanya umubyimba, bityo bikagabanya uburemere bw’ibicuruzwa byarangiye, kugera ku ntego nyamukuru yo kuzigama ingufu no kugabanya ibyuka bihumanya ikirere, no kumenya icyerekezo cy’ibicuruzwa “icyatsi kibisi”. Umwaka wa 2015 wibipimo byisoko rikoreshwa cyane kumasoko ya 280MPa ibyuma ntabwo byateganijwe. Mubyongeyeho, ibikubiye muri tekiniki yibisanzwe, nkubuso bwubuso hamwe nuburemere bwicyiciro, ntabwo bihuye nibyukuri bikenewe mubikorwa byubu. Mu rwego rwo kurushaho kunoza ikoreshwa ry’ibipimo ngenderwaho, Ikigo cy’ubushakashatsi bw’ubushakashatsi bw’inganda Metallurgical cyateguye ikigo cya Anshan Iron & Steel Co cyo gusaba umushinga mushya w’akazi mpuzamahanga w’ibicuruzwa. Muri gahunda yo gusubiramo, ibisabwa bya tekiniki yo mu cyiciro gishya byemejwe hifashishijwe impuguke zaturutse mu Buyapani, Ubudage n’Ubwongereza inshuro nyinshi, ziharanira kuzuza ibisabwa by’umusaruro n’ubugenzuzi muri buri gihugu no kwagura uburyo bwo gushyira mu bikorwa ibipimo ngenderwaho. Isohora rya ISO 4997: 2025 “Iterambere ry’imiterere ya Cold-Rolled Carbone Thin Steel Plate” ritera amanota mashya n’ubushakashatsi ku isi.
