ATEX Explosion Proof Certification
Сertification services for equipment and protective systems used in hazardous areas
ATEX certification is a mandatory requirement for certain categories of products placed on the EU market and is based on Directive 2014/34/EU, which defines the essential health and safety requirements for equipment used in hazardous areas such as environments with flammable gases, vapors, mists, or combustible dusts.
The conformity assessment route is determined in accordance with the applicable ATEX modules and depends on product category, design, and intended use.
our approach to ATEX certification
ATEX certification applies to equipment used in hazardous areas across industries such as oil and gas, chemical, petrochemical, and industrial manufacturing.
Typical product categories include:
Electrical equipment, motors, sensors
Control panels
Lighting systems
Instrumentation and monitoring devices
Mechanical equipment and assemblies
Equipment for gas and dust hazardous areas
ATEX Conformity Assessment Modules
ATEX certification is carried out in accordance with defined conformity assessment modules under Directive 2014/34/EU.
Module A (Internal Production Control / Technical Documentation Retention) — conformity assessment based on internal control of production by the manufacturer. The manufacturer ensures and declares compliance and retains the technical documentation for regulatory inspection where required.
Module B (EU-Type Examination) — assessment of product design against applicable requirements and harmonized standards. This results in an EU-Type Examination Certificate.
Module D/E (Production Quality Assurance) — assessment of the manufacturer’s quality management system ensuring ongoing conformity of production.
Module F (Product Verification) — verification of product conformity based on testing and inspection of individual products or batches.
Module G (Unit Verification) — assessment of individual products with full examination and testing.
The applicable module or combination of modules is determined based on product category, design, and intended use.
Explosion Protection Concepts
Compliance with ATEX requirements is achieved through the application of appropriate explosion protection types, as defined in relevant standards.
Ex d — Flameproof enclosure
Ex e — Increased safety
Ex i — Intrinsic safety
Ex p — Pressurization
Ex t — Protection by enclosure (dust environments)
The selected protection concept depends on the type of equipment and hazardous area classification.

How do ATEX and IECEx certification differ, and when is each required?
ATEX and IECEx are both certification systems for equipment intended for use in potentially explosive atmospheres, but they differ in their regulatory scope and geographic application.
ATEX is a mandatory European regulatory framework based on Directive 2014/34/EU. It is required for equipment placed on the market within the European Union and involves conformity assessment, technical documentation, and CE marking requirements.
IECEx is an international certification system based on IEC standards. It is not a legal requirement in itself but is widely recognized and accepted in many countries outside the EU. IECEx certification can facilitate market access by providing internationally recognized evidence of compliance with explosion protection requirements.
Although both systems are based on similar technical principles and often use the same IEC 60079 series standards, certification under one scheme does not automatically provide compliance under the other. Manufacturers targeting multiple markets frequently pursue both ATEX and IECEx certification to support international market access.
Is testing always required for ATEX certification?
In most cases, yes. ATEX certification typically requires testing and technical evaluation to demonstrate that equipment complies with the essential health and safety requirements of Directive 2014/34/EU and the applicable explosion protection standards.
The extent of testing depends on the equipment type, protection concept, category, and conformity assessment route. Testing may include evaluation of electrical, mechanical, thermal, and ignition-related characteristics, as well as verification of compliance with relevant EN and IEC standards.
In some cases, existing test reports, component certifications, or previously assessed designs may be used to support the conformity assessment process. However, a product-specific review is generally required to determine whether additional testing or evaluation is necessary.
Can existing products be certified under ATEX?
Yes. Existing products can often be certified under ATEX, provided they can demonstrate compliance with the applicable requirements of Directive 2014/34/EU and relevant explosion protection standards.
The certification process typically involves a review of the product design, technical documentation, risk assessment, and available test data. Depending on the product’s design maturity and the completeness of existing documentation, additional testing, evaluation, or design modifications may be required.
The feasibility of certifying an existing product depends on factors such as the protection concept, intended hazardous area classification, product age, and the availability of supporting technical evidence. A preliminary assessment is usually recommended to identify any gaps before starting the certification process.
What is the typical timeline for ATEX certification?
The duration of an ATEX certification project depends on the complexity of the equipment, the protection concept applied, the completeness of the technical documentation, and the scope of testing required.
For complex equipment, products requiring extensive testing, or projects involving design modifications and corrective actions may require several months.
Factors such as the availability of test samples, responsiveness during technical reviews, and the selected conformity assessment route can also influence the overall project timeline. An initial technical assessment can help identify potential gaps and provide a more accurate certification schedule.
Is ATEX certification more complex than other conformity assessment processes?
ATEX certification is often considered more complex than many other conformity assessment processes due to the high safety requirements associated with potentially explosive atmospheres.
Unlike many product regulations, ATEX requires detailed evaluation of ignition risks, protection concepts, equipment categorization, hazardous area classification, and compliance with specialized explosion protection standards. The assessment may also involve extensive technical documentation review, testing, quality assurance requirements, and Notified Body involvement depending on the equipment category.
The overall complexity varies by product type and intended application. However, because ATEX certification addresses risks that could lead to explosions and serious safety incidents, the evaluation process is generally more rigorous than that applied to conventional electrical or industrial equipment.
