    A. Ukongeza kwi-Q345A kunye ne-Q345B yamabakala, intsimbi kufuneka iqulethe ubuncinci beenkozo zokuzonwabisa ezihlaziyiweyo, i-NB, v, kunye ne-TI. Ngokweemfuno, umthengisi unokongeza izinto zokuphucula enye okanye ezingaphezulu. Elona xabiso liphezulu liya kuba njengoko lichaziwe kwitafile. Xa zidityanisiwe, i-NB + v + TI ayiphezulu kwe-0.22% b. Kwi-Q345, Q390, Q420 kunye neQ46O AMABAKALA AMABAKALA, MO + CR APIPI inkulu kune-0.30% c. Xa iCR kunye ne-NI yeBanga ngalinye isetyenziswa njengezinto ezintsukeni, umxholo weCR kunye no-NI akufuneki ube ngaphezulu kwe-0.30%; Xa kunyanzelekile ukuba kongeze, umxholo kufuneka uhlangabezane neemfuno ezikwitheyibhile okanye umiselwe ngumthengisi kunye nomthengi ngokubonisana.d. Ukuba umboneleli unokuqinisekisa ukuba umxholo we-nitrogen uhlangabezana neemfuno ezikwitheyibhile, uhlalutyo lwesiqulatho se-nitrogen asinakwenziwa. Ukuba al, nb, v, ti kunye nezinye izinto ze-nitrojeni zongezwa kwintsimbi, umxholo we-nitrogen awupheleli. Umxholo wokuCwangciswa kweNitrogen kufuneka ucaciswe kwiSatifikethi seMigangatho.
    E. Xa usebenzisa ialuminiyam epheleleyo, i-aluminium ye-aluminium Alt ≥ 00%%.

    A. Ukongeza kwi-Q345A kunye ne-Q345B yamabakala, intsimbi kufuneka iqulethe ubuncinci beenkozo zokuzonwabisa ezihlaziyiweyo, i-NB, v, kunye ne-TI. Ngokweemfuno, umthengisi unokongeza izinto zokuphucula enye okanye ezingaphezulu. Elona xabiso liphezulu liya kuba njengoko lichaziwe kwitafile. Xa zidityanisiwe, i-NB + v + TI ayiphezulu kwe-0.22% b. Kwi-Q345, Q390, Q420 kunye neQ46O AMABAKALA AMABAKALA, MO + CR APIPI inkulu kune-0.30% c. Xa iCR kunye ne-NI yeBanga ngalinye isetyenziswa njengezinto ezintsukeni, umxholo weCR kunye no-NI akufuneki ube ngaphezulu kwe-0.30%; Xa kunyanzelekile ukuba kongeze, umxholo kufuneka uhlangabezane neemfuno ezikwitheyibhile okanye umiselwe ngumthengisi kunye nomthengi ngokubonisana.d. Ukuba umboneleli unokuqinisekisa ukuba umxholo we-nitrogen uhlangabezana neemfuno ezikwitheyibhile, uhlalutyo lwesiqulatho se-nitrogen asinakwenziwa. Ukuba al, nb, v, ti kunye nezinye izinto ze-nitrojeni zongezwa kwintsimbi, umxholo we-nitrogen awupheleli. Umxholo wokuCwangciswa kweNitrogen kufuneka ucaciswe kwiSatifikethi seMigangatho. E. Xa usebenzisa ialuminiyam epheleleyo, i-aluminium ye-aluminium ye-alt≥0020%.
