Generally, golden yellow is normal, light red is slightly oxidized, and the surface is dark red and blue, which is serious oxidation. Any serious oxidation should be judged as waste disposal.

Ina theannta sin, ba cheart an chuid táthú den alt sreang aonair a shlánú agus tá cóireáil frith-chreimeadh ag teastáil ón táthú. Go ginearálta, níor chóir go mbeadh an chuid méadaithe den chomhpháirteach níos mó ná dhá uair an lamháltas trastomhas. Níor chóir go mbeadh an áit táthú níos lú ná 15 méadar, níl an fad idir an dá áit táthú den chiseal céanna mar an gcéanna sreang aonair, níor chóir go mbeadh an ciseal istigh níos lú ná 5 méadar, agus níor chóir go mbeadh an ciseal seachtrach níos lú ná 15 méadar. Nuair is sreang copair amháin an croí copair, ní cheadaítear táthú.
