B Gellir disgwyl i'r graddau a ddangosir yn y tabl hwn gyda'r llythyren B, megis 50B40, fod â rheolaeth boron leiaf 0.0005%. AMae'r graddau a ddangosir yn y tabl hwn gyda rhagddodiad llythyren E yn gyffredinol yn cael eu cynhyrchu gan y broses sylfaenol-trydan-ffwrnais. Mae'r holl rai eraill fel arfer yn cael eu cynhyrchu gan y broses aelwyd agored sylfaenol ond gellir eu gweithgynhyrchu gan y broses sylfaenol-trydan-ffwrnais gydag addasiadau mewn ffosfforws a sylffwr.
CMae'r cyfyngiadau sylffwr ffosfforws ar gyfer pob proses fel a ganlyn:
Ffwrnais drydan sylfaenol 0.025 uchafswm % Ffwrnais drydan asid 0.050 uchafswm %
Aelwyd agored sylfaenol 0.040 uchafswm % Aelwyd agored asid 0.050 uchafswm %
D Mae isafswm ac uchafswm cynnwys sylffwr yn dynodi duroedd wedi'u had-sylffwreiddio.
EGall y prynwr nodi'r uchafsymiau canlynol: copr, 0.30 %; alwminiwm, 0.050%; ac ocsigen, 0.0015%.
