Differentia explosio-Probatur BT et CT

CREPITUS-probationem rating:

CREPITUS-probationem apparatu cum CT4 rating stat pro Exd IIC T4. BT4 explosione-probationis apparatu aestimatur ut Exd IIB T4, quae est minus CREPITUS-probationem rating quam CT4 apparatu.

Applicability:

CT amplissima applicability.

Gas environment:

CT is an explosion-proof rating for acetylene and hydrogen levels. If there are gases like acetylene or hydrogen in the environment, CT-rated explosion-proof equipment is required. BT-rated equipment is not suitable for acetylene environments and is only considered a moderate CREPITUS-probatio level.
