What does the explosion-proof marking Ex db ib IIC T4 Gb mean?
An explosion-proof marking can be considered a proof document for explosion-proof equipment. Through the explosion-proof marking, one can understand the type of explosion-proof design adopted.
Explosive areas and explosion-proof zones, etc.
What is an explosion-proof marking? What does an explosion-proof marking signify? How do you interpret the explosion-proof marking on explosion-proof equipment?
For these issues, ZN Testing provides a detailed explanation for you.
For example, explosion-proof marking Ex db ib IIC T4 Gb.
This is a composite explosion-proof marking.
Ex indicates explosion-proof; explosion-proof equipment must be marked with the Ex symbol.
db ib refers to the explosion-proof protection type of the equipment, meaning it is both intrinsically safe and flameproof.
IIC refers to equipment suitable for explosive gas environments of IIC category gases (representative and).
T4 refers to the temperature category, indicating that the surface temperature of the equipment does not exceed 135°C.
Gb refers to the equipment protection level, applicable to Zones 1 and 2.
Above is an example of a common explosion-proof marking used for equipment in an explosive gas environment.
If used underground in coal mines or in environments with combustible dust, the explosion-proof marking on the equipment is different.
If it's an ATEX explosion-proof certification mark, it gets more complex.
