Ibipimo byamanota, imiterere yubukanishi nibisobanuro byumusaruro bigengwa nurwego mpuzamahanga ndetse nigihugu murwego rwibyuma bitagira umwanda. Mugihe AISI ishaje yimibare itatu sisitemu yo kubara ibyuma (urugero 304 na 316) iracyakoreshwa muburyo bwo gutondekanya ibyiciro byicyuma, hashyizweho uburyo bushya bwo gushyira mubyiciro.
Izi sisitemu zirimo inyuguti 1 + 5-nimero ya UNS, nka S30400, nkuko byasobanuwe na SAE na ASTM. Ibihugu byi Burayi bifata amahame ahuriweho na Euro. Ibi bihugu birimo gusimbuza cyangwa guhuza igihugu cyabyo ibipimo byihariye kugirango bigaragaze ibipimo ngenderwaho bya Euro. Ibindi bisobanuro bisimburwa harimo nimero ya BS na EN ishaje nka 304S31 na 58E.
Ibyiciro bimwe ntabwo bitwikiriwe numubare usanzwe kandi birashobora kuba amanota yihariye cyangwa kwitwa ukoresheje ibipimo byibicuruzwa byinzobere nka welding wire.
Ibipimo by'ibyuma bisobanurwa mu buryo burambuye mu ishyirahamwe ry’abongereza ry’icyuma “Ubuyobozi bw’ibyuma bitagira umwanda”, bizwi kandi nka BSSA "Ubururu".
Imbonerahamwe ikurikira irerekana urutonde rwibyuma bitagira umwanda, ibyashaje bya BS, nomero nshya ya UNS hamwe nizina rishya rya EN.

ASTM ntabwo yemera amazina mumutwe. Ayandi manota menshi nibisobanuro birahari.
Ibikoresho byatanzwe na Jindalai Steel Group byakozwe kugirango bikurikize ibipimo byinshi bitewe nibicuruzwa. Ibipimo nabyo bikubiyemo kurangiza ibikoresho.
Itsinda rya Jindalai Steel Group- uzwi cyane mu gukora ibyuma bitagira umwanda mu Bushinwa. Inararibonye mumyaka irenga 20 yiterambere mumasoko mpuzamahanga kandi kuri ubu ifite inganda 2 zifite umusaruro wa toni zirenga 400.000 buri mwaka. Niba ushaka kubona andi makuru yerekeye ibikoresho byuma bidafite ingese, ikaze kutwandikira uyu munsi cyangwa gusaba ibisobanuro.
