Econtra, in CT6 exemplar tenet Classis C explosio-probationem rating, BT4 exigentias obtegens et applicabilis cingulis vaporibus periculosis ut hydrogenii et acetylene. Apparatu T6 temperatura superficiei ponere debet non altiorem quam LXXXV°C.

In verbis of * temperatus genera, T6 significat summam salutem gradu, innuens inferiore apparatu superficies temperatus est potior.

Itaque, CT6 superiorem explosionem probationis classificationem habet.
