ATEX 2014/34/EU: Practical example of marking 

ATEX marking is essential to ensure that equipment meets essential safety requirements, providing an important guarantee for those who purchase, install, carry out maintenance or verification operations.

It certifies that the products comply with European regulations on safety in explosive atmospheres. 

The ATEX Directive 2014/34/EU: what the marking must contain 

The ATEX marking must include the following information: 

1. Manufacturer's name, trademark, and mailing address. 
2. Type, lot, or series number. 
3. CE marking, which certifies compliance with the essential safety requirements. 
4. Identification number of the Notified Body (in the case of equipment subject to examination by an external body), which certifies the ATEX production quality system (for example, "0051" is the IMQ number). 
5. Epsilon-x (Ex) mark, which identifies the product as suitable for use in environments with a risk of explosion. 
6. Group and category to which it belongs, with the indication "D" for dust or "G" for gas, depending on the type of hazard present in the environment of use.

A Practical Application Example 

Let's imagine that you have to illuminate a heating system powered by natural gas, located in an area classified as ZONE 1, where an explosive atmosphere could form. In this case, the ceiling lights to be installed must be compatible with ATEX safety specifications. 

What should the marking on this equipment look like? 

1. Equipment Groups: 
2. Group II: for locations with an explosive atmosphere caused by gases (excluding mining locations). 
3. Temperature classification: Since the ignition temperature of natural gas is 482°C, temperature class T1 applies. 
4. Category: Being in ZONE 1, category 2 equipment is used. 
5. Type of hazardous substance: gas, so the marking must include the letter G.
