Definition:
Im Vergleich zu allgemeinen Industrie- und Haushaltselektrogeräten, Explosionsgeschützte elektrische Geräte müssen mit den erforderlichen Kennzeichnungen versehen sein, die darauf hinweisen, dass es sich um explosionsgeschützte Geräte handelt. Dies wird als Explosionsschutzkennzeichnung bezeichnet.
Zweck:
Each explosion-proof electrical device should have its explosion-proof marking clearly displayed on its visible parts and nameplate. This system provides essential information, indicating that the marked electrical equipment is explosion-proof and specifying the types of brennbares Gas environments and hazardous areas where it can be safely used. Clearly, this is crucial information.
Composition:
The composition of the explosion-proof marking and examples of such markings consist of the following English letter combinations: Ex (Explosion-protect) represents “explosionsgeschützt,” followed by the explosion-proof type (which can also include the equipment protection level), equipment category, explosion-proof grade symbol (oder Temperatur), and/or equipment protection level symbol (oder Temperatur).
The representations of the explosionsgeschützter Typ (D, e, ich, P, Ö, Q, M, N, S), equipment classification (ICH, II) (IIA, IIB, IIC), temperature grading (T1, T2, T3, T4, T5, T6), and equipment protection levels (Ca, Cb, Ga; Ma, Mb, GB) are well-established. Also, we use these representations to exemplify the composition of explosion-proof markings for different types of explosionsgeschützte elektrische Geräte.
