Both ATEX and IECEx deal with equipment intended to operate in an environment with an explosive atmosphere, but they have different functions. ATEX certification is used for equipment that will go to the EU/EEA market, whereas IECEx facilitates international certification and acceptance in countries that have signed up for this scheme. It all depends on where your pump is going to be installed. Both types of certification could come in handy when exporting. Aocheng Group offers fuel handling equipment, so you need to know its certification status.
ATEX stands for the European Union directive dealing with equipment and protective systems meant for use in explosive atmospheres. The main legislative act here is Directive 2014/34/EU, where essential health and safety requirements for the covered goods are laid out.
Fuel handling equipment might work near petrol fumes, combustible gases, or some other flammable material that ignites under specific circumstances. An appropriate ATEX-certified design will help cope with the problem of ignition by equipment in such a hazardous environment.

Explore Product & SolutionsATEX divides hazardous areas into zones depending on the frequency and duration of the explosive atmosphere occurrence. In the case of gaseous and vaporous hazardous substances, the zones are 0, 1, and 2. For combustible dust, they are 20, 21, and 22.
The hazardous area classification determines what equipment group can be installed. For instance, a pump meant for Zone 1 cannot be used in Zone 0 just like that. The equipment must correspond to the zone classification and other criteria of the installation.
Therefore, selecting the right ATEX zone is a significant aspect of the pump selection process. The classification is based on the hazardous area assessment of the installation and not the use of the pump itself.
The conformity of ATEX might be achieved through an EU Notified Body depending on the particular category of the equipment and the type of the products. This organization assesses the particular product and then issues an EU Type Examination Certificate in case all the requirements are fulfilled.
The manufacturers should also take into consideration essential health and safety requirements stated by the Directive. The use of harmonized European standards in the area is helpful in proving conformity. However, it is important to note that ATEX is legislation and not the name of a certificate.
In case you buy an ATEX-certified pump, it is important to find out more information about your model and certificate. There is no automatic coverage for other models sold under the same brand.
IECEx is a global certification program which is based on standards set up by the International Electrotechnical Commission (IEC). With regard to the equipment installed in explosive environments, standards from the IEC 60079 series cover a number of technical criteria which are used in the assessment of explosion protection.
As opposed to ATEX, IECEx is not an EU directive. IECEx is a certification program that assists buyers and regulators to determine if certain equipment complies with international standards. The Certified Equipment Scheme provides Certificates of Conformity issued by approved IECEx Certification Bodies, and certificate details are available via the online IECEx Certification System.
The IECEx scheme is implemented in international projects and recognized in over 30 participating nations. But recognition does not guarantee automatic replacement of any local approval by the certificate.
IECEx equipment labels may feature Equipment Protection Levels (EPLs). In the case of a flammable atmosphere, EPLs comprise Ga, Gb, and Gc. For dust environments, there are Da, Db, and Dc EPLs. Such designations help to understand the protection level and the nature of hazardous locations where equipment may be employed.
IECEx may serve as a convenient initial framework of analysis for the fuel transfer pump that is planned to be shipped to several foreign markets. Yet, the ultimate decision about further approvals is based on the destination nation and installation conditions.
No, they are not the same. Explosion proofing entails various forms of protection, and a certificate refers to particular types of equipment and situations. IECEx provides a structure of testing for conformance with the right standard, and the certificate itself does not guarantee that the pump is good for all hazardous locations.
In essence, the same applies to explosion-proof certification. Buyers need to check for the type of protection method, group of gases/dusts, temperature class, equipment protection level, and ambient temperature class. This is much better than assuming that the product is just explosion-proof.
In the comparison of ATEX vs IECEx, the basic difference between them is in terms of market access. The former is EU legislation-based, whereas the latter is an international certification program. There is a great degree of similarity in technical requirements due to the fact that they use the same standards, namely those of the IEC 60079 series.
| Factor | ATEX | IECEx |
| Primary purpose | Legal market access in the EU/EEA | International certification and recognition |
| Legal or technical basis | EU Directive 2014/34/EU | IEC standards and IECEx scheme rules |
| Certificate | EU Type Examination Certificate, where applicable | IECEx Certificate of Conformity |
| Assessment body | EU Notified Body, where required | IECEx Certification Body |
| Main standards | Relevant EN 60079 standards and other applicable requirements | Relevant IEC 60079 standards |
| Area classification | Gas Zones 0, 1, 2; dust Zones 20, 21, 22 | Zones and EPLs, such as Ga/Gb/Gc and Da/Db/Dc |
| Geographic reach | Required for covered equipment placed on the EU/EEA market | Recognised in participating countries, subject to local rules |
| Typical use | Equipment sold or used in Europe | International projects and export markets |
Both systems assess whether equipment meets relevant safety requirements, but the certificate, legal basis, and approval process differ. An IECEx certificate alone does not satisfy the ATEX legal requirements for covered products placed on the EU/EEA market.
This depends on where the equipment is intended to be sold and used. For covered equipment used in a potentially explosive atmosphere in the EU/EEA market, the ATEX certificate is usually needed.
If the project is to be done in countries that recognize the IECEx certificate, this can aid in obtaining approval. But still, the requirements of each country need to be considered first.
The only consideration for a fuel pump that will serve only the European market would be ATEX. In the case of a project covering multiple international markets, IECEx might ease the task of technical evaluations in the countries participating in the scheme.
When it comes to both European and international markets, it may make sense to obtain both certifications. Due to similar technical requirements, IECEx tests and quality assurance documentation may help evaluate the pump for ATEX. The conformity, however, is not provided automatically; the European legal process will have to be followed.
Before placing an order on an ATEX fuel pump, it is necessary to make sure of the installation zone, the hazardous fluids and vapours, operating temperature, and destination market. It might also be useful to verify whether the entire assembly of the pump is certified or whether only some components are concerned, for instance, the motor.
For Aocheng Group products, buyers should request model-specific documentation and verify which approvals apply to the exact configuration being considered.

The meaning of each element should be checked against the product’s complete certificate and marking requirements.
| Marking element | Meaning |
| Ex | Indicates explosion-protected equipment |
| II | Equipment Group II, generally for surface industries rather than mining |
| 2G | ATEX Category 2 equipment for gas atmospheres, generally suitable for Zone 1 |
| Ex db | Flameproof enclosure protection method |
| IIB | Gas group classification |
| T4 | Temperature class; maximum surface temperature of 135°C under specified conditions |
| Gb | Equipment Protection Level for gas atmospheres, generally suitable for Zone 1 |
This example is illustrative, not a specification for every fuel pump. The marking must be consistent with the product’s certificate and the applicable standards.
Four marking specifications must be carefully considered when purchasing an ATEX-certified pump.
First of all, it is important to compare the marking zone and protection level with the hazardous area classification on-site. Second, the gas group has to be checked and make sure that it includes all substances that could potentially be present. Third, the temperature class should be checked to make sure that the maximum surface temperature is suitable for a specific hazardous environment. Finally, the permissible range of ambient temperatures has to be checked as well.
For example, the fact that a pump is intended for use in Zone 1 does not automatically mean that it could be used in Zone 0 as well. The same is true for T4 classification.
