Lo mgangatho wacetywa ukuba uhlaziywe ngo-2022 kwintlanganiso yonyaka ye-ISO/TC17/SC12 Steel/Continuously Rolled Flat Products Sub-Committee, kwaye waqaliswa ngokusesikweni ngoMatshi 2023. Iqela elisebenzayo lokuyila lahlala iminyaka emibini enesiqingatha, apho intlanganiso yeqela elisebenzayo elinye kunye neentlanganiso ezimbini zonyaka zabanjwa ukuze kuxoxwe kakhulu, kwaye ngo-Epreli 2025, uhlelo lwesithandathu lwe-ISO 4997:2025 ehlaziyiweyo “Structural Grade Cold Rolled Carbon Thin Steel Plate” yaqaliswa.
Lo mgangatho lolunye uhlaziyo lomgangatho wamazwe ngamazwe olukhokelwa yiTshayina emva kokuba iTshayina ithathe isikhundla sokuba ngusihlalo we-ISO/TC17/SC12. Ukukhutshwa kwe-ISO 4997:2025 lolunye uphuculo ekuthatheni inxaxheba kweTshayina kumsebenzi wokumisela umgangatho wamazwe ngamazwe kwicandelo leepleyiti zentsimbi kunye nemicu emva kwe-ISO 8353:2024.
Iimveliso zepleyiti yentsimbi eqhotsiweyo kunye ne-strip zesinyithi eziqingqiweyo zekhabhoni zizimisele ukuphucula amandla kunye nokunciphisa ubukhulu, ngaloo ndlela zinciphisa ubunzima beemveliso zokugqibela, zifezekisa injongo yokugqibela yokonga amandla kunye nokunciphisa ukukhutshwa komoya, kunye nokufezekisa ingcamango yemveliso "yentsimbi eluhlaza". Inguqulelo ka-2015 yomgangatho wamandla emveliso asetyenziswa kakhulu kwimarike angama-280MPa eeklasi zentsimbi azichazwanga. Ukongeza, umxholo wobugcisa womgangatho, ofana noburhabaxa bomphezulu kunye nobunzima bebhetshi, awuhlangabezani neemfuno zokwenyani zemveliso yangoku. Ukuze kuphuculwe ngakumbi ukusebenza komgangatho, iMetallurgical Industry Information Standards Research Institute iququzelele i-Anshan Iron & Steel Co. ukuba ifake isicelo seprojekthi entsha yomsebenzi osemgangathweni wamazwe ngamazwe wale mveliso. Kwinkqubo yokuhlaziywa, iimfuno zobugcisa zebakala elitsha zamiselwa ngokubonisana neengcali ezivela eJapan, eJamani nase-United Kingdom amaxesha amaninzi, zizama ukuhlangabezana neemfuno zemveliso nokuhlolwa kwilizwe ngalinye kwaye zandisa ububanzi bokusetyenziswa komgangatho. Ukukhutshwa kwe-ISO 4997:2025 “Iplati yentsimbi ebhityileyo ebandayo yeCarbon Thin Steel Plate” kutyhalela amanqanaba amatsha kunye nemigangatho ephandwe kwaye yaphuhliswa yiTshayina kwihlabathi liphela.
