A Isamba salezi zinto ezinhlanu akumele sibe ngaphezu kuka-1.00%.

B Ngokuncipha ngakunye okungu-0.01% kokuqukethwe okuphezulu kwekhabhoni, okuqukethwe okuphezulu kwe-manganese kuvunyelwe ukwanda ngo-0.06%, kodwa okuphezulu akukwazi ukudlula u-1.35%.

C Ukwehla ngakunye okungu-0.01% kokuqukethwe okuphezulu kwekhabhoni kuzovumela okuqukethwe okuphezulu kwe-manganese ukuthi kwande ngo-0.06%, kodwa okuphezulu akumele kudlule u-1.65%.
