Codifica ATEX
Per soddisfare esattamente i requisiti della Direttiva ATEX 2014/34/UE, le torce Peli sono testate per assicurare che non siano a rischio di infiammabilità quando si opera in ambienti rischiosi. Utilizzando appositi laboratori, le torce sono testate per assicurare che esse possano superare rigorosi test di urto e caduta, esposizioni ad ambienti ostili e che soddisfino almeno il livello di protezione IP54 contro l'ingresso di acqua e polvere. Longevità e sicurezza sono assicurate dalla progettazione. Le torce con omologazioni relative al gas non richiedono test dell'impatto e l'omologazione relativa al gas richiede unicamente IPX4 (non il test di resistenza alle polveri IP5X. L'approvazione per le polveri richiede il test di resistenza alle polveri IP6X).
Ogni torcia certificata da ATEX dovrebbe avere un codice stampato sul proprio corpo. Questo codice avvisa gli utenti in quale zona la torcia può essere utilizzata in sicurezza senza rischio di esplosione.

- La temperatura di auto-ignizione è la temperatura in C a cui un gas si accende spontaneamente senza un'altra fonte di ignizione
- Dal momento che NON vi sono correlazioni tra energia di ignizione e temperatura di ignizione per i raggruppamenti del gas, è stato determinato un codice di temperatura
- La Classe di temperatura si basa sull'uso a una temperatura ambiente di -20/40 C. Se la temperatura ambiente differisce da tale range, è necessario indicarlo.
* Gas Group

180 µJ+ 60 - 180 µJ 20 - 60 µJ |
Atmospheres containing propane/butane/oil/ammonia Atmosphere containing ethylene/ether Atmosphere containing hydrogen/acetylene |
- Gases are divided into two groups based on the LEL and UEL values.
* Dust Group
Dust Group | Substance | Selection of Equipment | Examples |
IIIA | Flammable fibers > 0,5mm | Explosive surface > 1000 hrs/yr | Wood shaving |
IIIB | Non-conductive dust with electrical resistivity > 103 Ωm | Explosive surface between 10 and 1000 hrs/yr | Saw dust, flour |
IIIC | Conductive dust with electrical resistivity ≤ 103 Ωm | Explosive surface between 10 and 10 hrs/yr | Metal dust |
- Dust areas are defined as group III and refers to equipment intended for use in spaces with an explosive dust atmosphere other than mines susceptible to firedamp.
Maximum Surface Temperature
Group III electrical equipment is marked with a temperature with ‘T’ prefix detailing the actual maximum temperature that may be found on any surface accessible by a potentially explosive dust atmosphere. Ignition temperature of a specific dust hazard must be higher than maximum surface temperature displayed on electrical equipment.
