Yoyamba, muyeso yaku Europe ya DX51D, D imayimira 'yokutidwa', zomwe zikutanthauza kuti chitsulo chapamwamba ndi mbale yachitsulo yopukutidwa.X amatanthauza 'zinc'.Pakati pawo, 51D imayimira cholinga.51D imayimira chitsulo chokhazikika.Kapena 52D m'kalasi amatanthauza kuti bolodi ndi bolodi yosindikizira.Ngati ndi 53D, pamwamba pake amagwiritsidwa ntchito pojambula mozama.Pamene nambala ya X mu 5XD ikuwonjezeka, zikutanthawuza kuti kukhazikika kwabwino, kumapangitsanso kufewetsa kwamphamvu.Miyezo yaku Europe nthawi zambiri imatengedwa ndi zitsulo zakale zaboma, monga Anshan Iron ndi Steel, Benxi Iron ndi Steel, Wuhan Iron ndi Steel, ndi zina. Zizindikiro zaku Europe nthawi zambiri zimakhala monga: DX51D+Z/AZ DX52D+Z/AZ DX53D +Z/AZ DX54D+Z/AZ.

Yachiwiri ndi American Standard ASTM A792.Ponena za muyezo waku America, kukhudzana kochepa ndi anthu, kotero sindingathe kufotokoza m'mawu pakadali pano.Chonde ndikhululukireni.Komabe, zimadziwika kuti American Standard nthawi zambiri imatengedwa ndi mabizinesi ena apakhomo.Monga: Yehui China, South Korea ndi mphero zina zachitsulo.Malonda akunja amabizinesi ogwirizana ndi mabizinesi akuluakulu apakhomo ndi apakhomo, kotero kuti akwaniritse malonda akunja, ndizachilengedwe kutengera muyezo waku America.

Mtundu wachitatu, SGCC yokhazikika yaku Japan, nayi mawu oyambira apadera a zilembo ndi manambala azinthu zosanjikiza za zinc kumbuyo kwa muyezo waku Japan, monga muyezo watsiku ndi tsiku SGCC+Z.Chizindikiro cha kulemera kwa Zinc chidzawonjezedwa pambuyo pa Z, monga SGCC + Z27.Ndiye anthu ena angaganize kuti + Z27 zikutanthauza kuti zinc zili ndi magalamu 27 pa lalikulu mita?ayi.Z27 ndi Z270 mu muyezo European pamwamba ndi tanthauzo lofanana, ndiye tanthauzo la malata 270 magalamu.
