Condition pakutumira:

Term	Symbol	Tsanangudzo
Kutonhora-kupedzwa/zvakaoma (inotonhora-yakapera sekudhonzwa)	BK	Hapana kupisa kurapwa mushure mekupedzisira kutonhora-kuumba maitiro. Iwo machubhu saka anongova nekushomeka kwakaderera.
Kutonhora-kwapera/nyoro (zvishoma kutonhora-kushanda)	BKW	Mushure mekugadzirisa kupisa kwekupedzisira kune chiedza chekupedza kupfuudza (kudhirowa kunotonhora) Nekugadzirisa kwakakodzera kunotevera, tube inogona kutonhora-yakaumbwa (somuenzaniso yakakotama, yakawedzerwa) mukati meimwe miganhu.
Annealed	GBK	Mushure mekupedzisira kutonhora-kuumba maitiro machubhu anonamirwa mumhepo inodzorwa kana pasi pevacuum.
Normalized	NBK	Iwo machubhu anonamirwa pamusoro peiyo yepamusoro shanduko nzvimbo munzvimbo inodzorwa kana pasi pevacuum.
