Likarolo tsohle li kentsoe maemong a IIB. Leha ho le joalo, Thepa ea T4 e na le moeli oa mocheso o holimo oa 135 ° C, athe thepa ea T5 e lekanyelitsoe ho 100°C. Lithempereichara tse tlase tse tlase li bontša polokeho e kholoanyane. Kahoo, lisebelisoa tse lumellanang le litekanyetso tsa BT5 li boetse li lumellana le BT4, empa se fapaneng ha se sebetse.
