Isimbuku sezi zinto zintlanu akufuneki sibe ngaphezulu kwe-1.00%.

B Xa kuncipha nge-0.01% kumxholo wekhabhoni ophezulu, umxholo we-manganese ophezulu uvumelekile ukuba unyuke nge-0.06%, kodwa ubuninzi abunakudlula i-1.35%.

C Ukwehla ngakunye kwe-0.01% kumxholo wekhabhoni ophezulu kuya kuvumela umxholo we-manganese ophezulu ukuba unyuke nge-0.06%, kodwa ubuninzi akufuneki budlule kwi-1.65%.
