Three guides published on the same day
The Round 6 update adds exactly three English articles. Each starts with a direct answer, then shows buyers which controlled records and project inputs require further review.
| New guide | Question answered | Main buyer takeaway |
|---|---|---|
| ATEX 114 vs ATEX 153: Who Is Responsible for What? | Which duties belong to product economic operators, and which remain with the employer responsible for the workplace? | Keep product conformity evidence separate from workplace explosion-risk responsibilities |
| IECEx Certificate X vs U: Conditions of Use and Component Limits | Does a certificate number identify specific conditions of use or an Ex component? | Read the complete certificate and its conditions or limitations before approving the item |
| Explosion-Proof Control Stations: 12 Buyer FAQs | Which technical and document inputs should be settled before a control station is configured? | Define the hazardous-area duty, operators, electrical functions, entries and evidence for the exact configuration |
The three articles are connected by one practical principle: a product description is a starting point, not proof that a particular model, suffix or assembly is suitable for a particular installation.
Why these topics belong in one buyer update
Ex procurement often crosses several responsibility boundaries. A manufacturer controls product design and conformity work. An importer or distributor has its own checks when placing or making a product available on the EU market. An employer controls the workplace risk assessment, zone classification and safe use. A buyer or engineering team must connect those records without treating them as interchangeable.
The new guides address three common points where that connection can fail.
Separate product duties from workplace duties
The first guide explains that "ATEX 114" and "ATEX 153" are industry shorthand, not the official titles of the directives. Directive 2014/34/EU covers products for potentially explosive atmospheres and the duties of manufacturers and other economic operators. Directive 1999/92/EC addresses minimum workplace protection requirements and employer duties.
The distinction matters at the enquiry stage. A compliant product does not classify a workplace, create an explosion protection document or prove that the selected model fits the site's gas, dust, temperature, ambient and installation conditions.
Read X and U as different certificate signals
The second guide focuses on two suffixes that can change how an IECEx record must be used. An X suffix directs the reader to specific conditions of use. A U suffix identifies an Ex component certificate, so the component is not approved as complete stand-alone Ex equipment merely because it has a certificate number.
The buyer should open the current controlled record, check its status and issue, and read every schedule, condition and limitation. The IECEx certificate and ATEX document verification guide provides a broader evidence workflow for matching the legal manufacturer, model, marking and document status.
Configure control stations before approval
The third guide turns a broad request such as "Zone 1 control station" into a structured set of questions. The project team still needs to define the atmosphere, required protection level or category, temperature duty, ambient range, enclosure and operator functions, electrical ratings, cable entries, mounting and required documents.
Those details must be assessed together for the exact configuration. Buyers can use the Ex marking guide to interpret the complete marking and the IEC 60079-14:2024 buyer checklist to prepare installation-related inputs before ordering.
A practical reading sequence
Start with the ATEX responsibility guide when an EU project needs a clear division between product-market roles and workplace duties. Continue with the IECEx suffix guide when a certificate number ends in X or U, or when an offered item is described as a certified component. Use the control station FAQ when converting the approved project basis into a model and configuration enquiry.
For projects comparing regulatory and international certification routes, the ATEX vs IECEx guide explains why the two systems should not be treated as interchangeable labels.
This sequence helps a buyer ask better questions. It does not approve equipment, allocate contractual liability or replace review by the competent people responsible for the project.
Evidence boundaries remain unchanged
Publishing a guide does not extend the scope of a certificate or declaration. A category page, product photograph, marketing name, related certificate, sample nameplate or similar enclosure cannot establish conformity or project suitability for an exact model.
The responsible team should obtain current evidence for the exact legal manufacturer, model, suffix, options and configuration. It should compare the offered item with the official certificate record, schedules, conditions, declaration, instructions, drawings and destination requirements as applicable.
Current MMAIATEX certification status
The public MMAIATEX About page states that ATEX, IECEx and CCC certification work is in progress. These guides do not establish completed ATEX, IECEx or CCC certification for any particular displayed product, category or configuration.
Before specification or purchase, request the current model-specific document set and independently verify the applicable status, scope and conditions through the relevant official source and responsible project process.
Safety disclaimer
These articles provide general educational information. They are not certificates, declarations of conformity, legal opinions, area-classification studies, explosion protection documents, installation designs or engineering approvals. EU directives are implemented and enforced through applicable national systems, and other local laws, standards and project rules may apply.
Hazardous-area classification, product selection, installation, inspection, operation, maintenance and modification must be controlled by competent personnel using site-specific data and the exact current product documentation.
Request model-specific information
Send the destination country, approved Zone, required EPL or ATEX category, gas or dust group, temperature and ambient requirements, electrical functions, operator schedule, cable-entry details, mounting and required documents. MMAIATEX can identify potentially relevant product information for the responsible buyer or engineer to assess.
