1st line (IIC) are most dangerous gases. How to read and use this table? Hot surfaces become dangerous ≥ 135°C. For that reason all Ex equipment shall be selected having a T class T4, T5 or T6. The higher the T class, the lower the belonging acceptable temperature. (T6 classified sites are most dangerous, T6 certified equipment is most safe!)

The IEC (International Electrotechnical Commission) is the world’s leading organization that prepares and publishes International Standards for all electrical, electronic and related …

IECEx is an international system for certification of equipment for use in explosive atmospheres. Its quality assessment specifications are based on standards prepared by the International Electrotechnical Commission (IEC).

To comply with ATEX/IECEx regulations, all equipment and protective systems that are used in hazardous areas must be marked legibly and indelibly with a specific set of letters/numbers.

ATEX and IECEx are both essential certifications for equipment used in explosive environments, but they serve different legal and geographical purposes. ATEX is legally required in the European Union, while IECEx is an internationally recognized certification based on …

For Group I electrical explosion-proof equipment there is no marking indicating the temperature class. The maximum surface temperature marking, according to the assigned EPL. ① The symbol «Ex» which indicates that the Ex non-electrical Equipment corresponds to one or more of the types of protection.
