Yes, machine builders can self-attest certain ATEX assemblies, provided they are using pre-certified equipment and/or simple apparatus and/or simple devices and the overall assembly does not introduce new ignition hazards. However, a rigorous ignition hazard assessment must be documented.

The primary difference lies in regional and legal jurisdictions. ATEX is a legal requirement mandatory within the European Union, UK&NI and EFTA and adopted via UKEX regulations in the UK. IECEx is an international certification scheme recognised globally to facilitate international trade. HazLoc refers to the hazardous location certification system used in North America (Class/Division or Class/Zone systems). Equipment manufacturers must understand all three to sell products globally.

A panel builder requires 3rd party certification when designing a panel if they are incorporating non-certified components into the enclosure, component certified parts (e.g. empty flameproof boxes populated with control gear) or if they “Assembly” is deemed to be “Equipment”. It is important to differentiate between “Assembly” and “Equipment”. Assemblies may be self-attested to be compliant and under certain conditions for all Zones/Categories, equipment may be self-attested (self-certified) generally for Zone 2/22 (Category 3G/3D) electrical or mechanical equipment, and for Zone 1/21 (Category 2G/2D) for mechanical equipment (with file lodging at a Notified Body).

Advanced ATEX training shifts your commercial team from transactional selling to value-based technical consultation. In highly regulated hazardous industries, sales professionals who can interpret complex nameplates, cross-reference ATEX/IECEx standards, and navigate compliance requirements build deeper trust, reduce specification errors, and successfully justify a premium price point over untrained competitors.

Investing in specialised compliance training increases engineering and sales autonomy, which directly boosts job satisfaction and retention. Providing clear career development paths in complex engineering sectors like explosion protection reduces costly turnover and keeps critical regulatory knowledge within your organisation.

The primary difference is the regulatory framework each quality audit serves. An ATEX QAN (Quality Assurance Notification) is mandatory for manufacturing equipment intended for the European and UK markets under ATEX/UKEX compliance. An IECEx QAR (Quality Assessment Report) is the international equivalent required to support IECEx product certification globally. While both evaluate your quality management system (typically building on ISO 9001). These can typically be bundled into a single audit by a Certification/Notified Body as they will typically be based on IEC/ISO80079-34 for both ATEX & IECEx.

Yes if you are altering any of the explosion protection properties or using component certified parts that need to be converted into equipment certificates.

No if you only assemble pre-certified parts and simple apparatus and simple devices and all are within the manufacturer’s and certification parameters.

The biggest risk is counterfeit certification or unapproved component substitutions by sub-tier suppliers. Sourcing teams must know how to verify the live status of ATEX certificates and IECEx databases. A minor component swap by an overseas supplier—such as changing a cable gland or an internal terminal block to a non-certified equivalent—can completely invalidate your equipment’s overall certification and expose your company to massive legal liability, or worse a catastrophic incident causing loss of life, damage to property and infrastructure.

For a CEO, Ex compliance is fundamentally an exercise in risk management, legal liability protection, and market access. Non-compliance can result in catastrophic industrial incidents, costly product recalls, criminal prosecution under UK regulations, and complete exclusion from high-margin global energy and chemical markets. Executive-level overviews empower leadership to accurately budget for compliance, manage regulatory risk, and align product roadmaps with international trade requirements.
