IECEx Certification: how to reduce risk and delays in hazardous area projects

Motors, Senza categoria

Operating in explosive atmospheres leaves no room for improvisation. A single spark, a non-compliant component, or a supplier without the right certifications can turn a job site into an incident, an audit into a fine, an international project into months of delay. For Procurement Managers, Plant Managers and Engineering Managers working in Oil & Gas, petrochemical, water treatment and heavy industry, choosing truly compliant IECEx electric motors is more than a technical decision: it directly impacts safety, lead times and legal liability.

OME Motors has obtained IECEx certification, the international benchmark standard for equipment intended for use in hazardous areas. This article explains what this means in practice for buyers, how IECEx differs from ATEX, and why this certification reduces compliance risk across the entire supply chain.

The real risks of operating in explosive atmospheres

The consequences of installing non-compliant equipment in a Zone 1 or Zone 2 classified area go far beyond what is typically considered at the procurement stage:

Safety incidents: a non-certified motor exposed to flammable gases or dust can trigger explosions, causing injury and damage to assets.
Project delays: supplying components without valid certification in the country of installation blocks commissioning, SAT and start-up activities.
Legal exposure: in case of an incident, liability extends across the entire supply chain, from the manufacturer to the end user.
Hidden costs: emergency replacements, plant downtime and contractual penalties can far exceed the original supply value.

In this scenario, choosing a supplier of IECEx zone 1 / zone 2 motors is not a commercial extra: it is an operational requirement.

What is IECEx certification?

The IECEx (International Electrotechnical Commission System for Certification to Standards Relating to Equipment for Use in Explosive Atmospheres) is an international certification scheme that confirms the conformity of equipment, services and personnel operating in explosive atmospheres with the IEC 60079 series of standards.

Unlike regional certifications, IECEx is recognised globally and relies on a unique mechanism: every certified product receives a Certificate of Conformity (CoC) issued by an accredited body and immediately verifiable online on the official IECEx portal. This means that an IECEx motor manufactured in Italy can be installed in a plant in the Middle East, Southeast Asia or Latin America without going through additional local certification procedures.

Where it applies

IECEx certification is required, or strongly recommended, in any international project involving the presence of flammable gases, vapours or combustible dust:

Refineries and petrochemical plants
Offshore platforms and onshore installations across the entire Oil & Gas value chain
Natural gas treatment and distribution plants, including pipelines
Chemical and pharmaceutical facilities
Storage and handling of combustible dust (grain, sugar, metal powders)

IECEx vs ATEX: differences and when each certification is required

One of the most frequent questions from buyers concerns the difference between ATEXvsIECEx. They are two complementary systems, but they apply to different scopes.

Geographic scope

ATEX: Directive 2014/34/EU, mandatory for placing equipment intended for explosive atmospheres on the market within the European Union.
IECEx: a voluntary scheme with international recognition, accepted in more than 30 countries including Australia, Singapore, the United Arab Emirates, South Africa, Brazil and the United States (in combination with other local schemes).

Acceptance

ATEX is a legal requirement for placing products on the European market. IECEx is a global system that drastically reduces the need for multiple country-by-country certifications, accelerating project approval for EPC contracts with international scope.

Typical use cases

ATEX only: projects whose operational scope remains entirely within the EU.
IECEx only: supplies destined for non-EU countries that have adopted the IECEx scheme.
ATEX + IECEx: international EPC projects, multinational contractors, and end users requiring maximum flexibility on the final destination of the asset. This is the combination most frequently requested in oil & gas electric motors.

OME Motors offers electric motors available in both ATEX and IECEx versions, allowing buyers to standardise their supply chain on a single partner for all projects, European and international alike.

Why IECEx certification matters for buyers

Translating a technical certification into business impact is what really makes the difference during vendor selection. Here is what buyers gain by choosing an IECEx supplier:

Faster project approvals

The IECEx Certificate of Conformity is verifiable online and is accepted by all major global engineering contractors without the need for supplementary documentation or local testing. This significantly reduces vendor qualification timelines.

Simpler international compliance

A single certification recognised in over 30 countries removes the risk of having to manage parallel certification processes, translations, local approvals and the related costs.

Reduced audit risk

Third-party inspections, end-user audits and insurance reviews find in IECEx documentation an immediate guarantee of compliance with the highest international standards.

Supplier credibility

Obtaining and maintaining IECEx certification requires a robust quality management system, controlled production processes and qualified personnel. It is an objective indicator of the manufacturer’s technical and organisational reliability.

What OME Motors offers: beyond certification

Certification is a necessary condition, but not a sufficient one. What sets OME Motors apart from other IECEx-certified manufacturers is the combination of compliance, production flexibility and response times.

Competitive lead times: in-house manufacturing in Italy with delivery capabilities above market average, especially on critical supplies and spare parts.
Dual ATEX and IECEx certification: a complete range covering both the European market and international projects through a single point of contact. The portfolio includes OMEX low voltage motors and OMEX high voltage motors for high-power applications.
Custom solutions: motors configurable to customer specifications in terms of power, voltage, temperature classes, types of protection (Ex d, Ex de, Ex e, Ex nA), mounting arrangements and accessories.
Reliability in harsh environments: engineering oriented to offshore installations, tropical environments, corrosive atmospheres and heavy-duty operating cycles.
Direct technical support: dialogue between the OME engineering team and the customer’s designers from the quotation stage, avoiding late-stage modifications and document revisions.
Global aftersales coverage: a worldwide service network guarantees post-sales support, spare parts and on-site interventions wherever the motor is installed.

Applications: where OME IECEx certified motors are used

OME Motors IECEx motors are used across a wide range of applications in Zone 1 and Zone 2 classified areas:

Pumps: centrifugal and positive displacement, for process duties and hydrocarbon handling
Compressors: for natural gas, process air and auxiliary services
Fans: axial and centrifugal, for fume extraction, safety ventilation and cooling
Offshore installations on platforms and FPSOs
Onshore installations in refineries, terminals, pipelines and petrochemical plants
Industrial wastewater treatment systems where biogas is present

Checklist: how to choose an IECEx motor supplier

For anyone evaluating a new supplier for hazardous area motors, here is an operational checklist to use during vendor qualification:

Certifications: verify the simultaneous presence of IECEx and ATEX, and coverage of the required types of protection (Ex d, Ex e, Ex nA, Ex tb).
CoC traceability: the certificate number must be verifiable on the official IECEx portal.
In-house production capacity: prefer manufacturers that produce internally rather than simple assemblers.
Stated and actual lead times: ask for references on recent supplies to validate consistency between promises and deliveries.
Configuration flexibility: ability to handle technical variants without disproportionate price uplifts or schedule extensions.
After-sales support: availability of spare parts, technical assistance and non-conformity management.
Documentation: completeness and quality of data sheets, manuals, declarations of conformity and technical dossiers.
