ATEX and IECEx address equipment for potentially explosive atmospheres through different frameworks. ATEX establishes EU legal requirements and conformity-assessment procedures. IECEx is an international certification system based on applicable IEC standards.
For lighting buyers, neither an ATEX logo nor an IECEx reference is enough to approve a luminaire. The documents must cover the exact model, configuration and intended installation.
This guide explains the differences and provides a practical document checklist for contractors, consultants and procurement teams in Saudi Arabia and the GCC.
| Comparison | ATEX | IECEx certified equipment scheme |
|---|---|---|
| Framework | EU legislation for relevant equipment and protective systems | International conformity-assessment scheme |
| Main basis | Essential health and safety requirements under Directive 2014/34/EU | Applicable IEC standards and scheme requirements |
| Assessment route | Depends on the equipment and category | Independent testing and certification |
| Key evidence | EU Declaration of Conformity and documents required by the applicable route | IECEx Certificate of Conformity and associated information |
| Buyer’s task | Confirm the appropriate conformity route and product coverage | Verify the certificate record, scope and status |
The European Commission explains that Directive 2014/34/EU defines requirements and conformity-assessment procedures before relevant products are placed on the EU market. IECEx separately explains that its certified equipment scheme requires independent testing and certification.
No. ATEX conformity-assessment procedures depend on the equipment and category.
Some routes require notified-body involvement. Others allow the manufacturer to demonstrate conformity without third-party product certification.
Consequently, “ATEX certified” should lead to a request for the applicable documentation and assessment route. It should not be treated as proof that every product underwent the same process.
An EU-type examination certificate also does not replace the manufacturer’s EU Declaration of Conformity where that declaration is required.
No. The schemes can share technical evidence, but their documents and purposes differ.
IECEx test and quality-assessment information can support ATEX conformity assessment. That does not make an IECEx certificate, by itself, the complete ATEX documentation package.
When a specification requests both, ask the supplier to provide the relevant documents for each and identify any differences in model coverage or operating conditions.
Start with the project’s approved technical and procurement requirements.
Clarify:
An international certificate should not be treated as automatic approval for every country, project or installation.
For an introduction to luminaire types and applications, read our Explosion-Proof Lighting Guide.
Use the official IECEx online certificate system to locate the certificate.
Compare the record with the supplier’s submission:
IECEx makes equipment certificate information available through its online system. Check the record rather than relying solely on a cropped certificate image or catalogue badge.
If the quoted brand or model differs from the certificate, request documented clarification of its coverage.
These suffixes identify information that needs attention.
| Suffix | Meaning | Buyer’s action |
|---|---|---|
| X | Specific conditions of use apply | Read the conditions and establish how they will be met |
| U | The certificate concerns an Ex component | Confirm how the component is assessed within the complete equipment |
A component certificate does not independently approve a complete luminaire for installation. IECEx distinguishes component certificates from equipment certificates and identifies the associated limitations.
Read the marking as a complete statement, supported by the certificate and instructions.
| Marking element | What it helps identify |
|---|---|
| Protection symbols | The techniques used to control ignition risks |
| Equipment group | The gas or dust grouping covered |
| Temperature information | Relevant surface-temperature limits |
| Equipment Protection Level | The assessed protection level |
| Ambient-temperature information | Permitted surrounding operating conditions |
| Certificate reference | The supporting certification record |
IECEx certificate guidance identifies these elements as part of the equipment’s marking information. A product may combine more than one protection technique.
Avoid approving equipment based on a single term such as “IIC,” “IP66” or “explosion-proof.”
Do not assume that it does.
Ask whether the documents cover the offered:
An optional emergency configuration should be reviewed against its own documented operating conditions. A standard model’s brochure should not be used to fill missing information by assumption.
When reviewing Alrouf’s B-Series high bay, Ex-Proof Linear Light or AR-EX-SC hand lamp, request the documentation covering the exact model and configuration offered.
Confirm which ATEX or IECEx documents apply, including any restrictions affecting voltage, emergency options, operating temperature or accessories.
| Document | Purpose |
|---|---|
| Datasheet and complete ordering code | Identify the proposed equipment |
| Proposed nameplate or marking details | Connect the product to its protection information |
| Applicable certificates and schedules | Establish scope and conditions |
| EU Declaration of Conformity, where applicable | Record the manufacturer’s conformity declaration |
| Installation and maintenance instructions | Identify permitted installation and service arrangements |
| Drawings and accessory schedule | Define the supplied assembly |
| Photometric information | Support the lighting design |
| Compliance schedule | Identify conformity, exclusions and deviations against the project specification |
Resolve differences between the quotation, datasheet and certificate before approving the submission.
They serve different purposes. Select equipment against the project’s requirements and review the relevant evidence rather than choosing by the label alone.
CE marking alone does not identify the complete hazardous-area protection characteristics. Review the applicable conformity documents, Ex marking and product instructions.
No. It means specific conditions of use apply. Suitability depends on whether those conditions and the other selection requirements can be met.
No. Component or accessory documentation does not independently establish the conformity of the complete luminaire.
Request the technical submission early enough to resolve model coverage, conditions and deviations before committing to the equipment.

Contact Alrouf with your specification, classification details, quantities and installation conditions. Ask the team to confirm the available configuration and supporting documentation for review.
