How MMAIATEX ATEX and Ex q guides support buyers
The three guides address different stages of an evidence-led purchasing decision. The first maps legal roles before an ATEX product reaches the European Union market. The second explains one protection marking without turning a standard's scope limits into product ratings. The third separates ordinary circuit-breaker performance from the additional evidence needed for finished hazardous-area equipment or an assembly.
This release is an editorial update, not a product launch, certification announcement, customer case study or claim about a completed project. MMAIATEX published the material to help readers ask more precise questions before they rely on a nameplate, certificate cover, marketing description or representative photograph.
| New guide | Primary question answered | Useful starting point for |
|---|---|---|
| ATEX manufacturer and authorised representative duties | Which Article 6 duties remain with the manufacturer, and which specified Article 7 tasks may be covered by a written mandate? | Manufacturers, EU representatives, importers, procurement and compliance teams |
| Ex q powder filling | What does the public IEC 60079-5 scope say, and what must still be verified in the full marking and certificate evidence? | Electrical engineers, Ex specialists, equipment buyers and document reviewers |
| Circuit-breaker buyer FAQs | Why does IEC 60947-2 performance evidence not by itself establish explosion protection for finished equipment or an assembly? | Panel designers, buyers, EHS teams and responsible installation parties |
Guide 1: ATEX manufacturer and representative duties
ATEX Manufacturer vs Authorised Representative Duties compares the roles defined by Directive 2014/34/EU Articles 6 and 7. It explains that an authorised representative acts through a written mandate for specified tasks, while compliant design and manufacture and the duty to draw up technical documentation remain with the manufacturer.
The guide also separates this relationship from importer and distributor duties. That distinction matters when one organisation performs more than one economic-operator role or when a commercial title is mistaken for a legal appointment. Readers are directed to the current EUR-Lex consolidated text and the authentic Official Journal act for controlling source material.
Guide 2: Ex q scope and marking boundaries
Ex q Powder Filling: Scope and Marking Explained uses the current public IEC and IECEx pages checked on September 13, 2026. It explains that IEC 60079-5:2015+AMD1:2022 CSV covers powder filling q for equipment, parts and Ex Components intended for explosive gas atmospheres within its public scope.
The article treats the published current, voltage and power figures as document-scope ceilings, not automatic ratings for a product. It also explains why q alone does not establish equipment group, EPL, temperature information, ambient range, dust suitability or current certification. A buyer still needs the exact identity, complete marking, certificate and schedules, controlled configuration and instructions.
Guide 3: Circuit-breaker questions for Ex equipment
Explosion-Proof Circuit Breaker: 12 Buyer FAQs answers common questions about ratings, isolation, Ex enclosure integration, operating interfaces, temperature evidence and final selection responsibility.
The central boundary is direct: IEC 60947-2 circuit-breaker compliance does not by itself make a device suitable for an explosive atmosphere. The finished equipment or assembly must be supported by the applicable Ex marking, configuration and conformity evidence. The guide also makes clear that an enclosure, handle, IP rating or product photograph cannot prove that evidence.
A practical way to use the new material
Use the guides as a question set, not as an approval shortcut:
- Identify the legal manufacturer, supply-chain roles and destination market.
- Define the hazardous-area classification, required EPL, atmosphere, group, temperature limits and ambient range.
- Match the exact model and suffix to the complete marking, ratings, certificate status, schedules and instructions.
- Check component and assembly boundaries before accepting substitutions or integration changes.
- Record unresolved questions for the responsible manufacturer, conformity body, designer, installer or legal adviser.
Each page includes a current-review date, direct answer, comparison or checklist content, primary-source links, current MMAIATEX certification status and a safety boundary. These features help human readers and search or answer systems distinguish sourced facts from limitations and procurement guidance.
Current MMAIATEX certification status
The public MMAIATEX About page states that ATEX, IECEx and CCC certification work is in progress. MMAIATEX Explosion-proof Technology (Zhejiang) Co., Ltd. does not claim in this release that an identified product, component or assembly has completed those processes. Publication of a guide, use of a standard reference, an IP rating or a representative product photograph is not product-specific certification evidence.
Safety and legal disclaimer
These guides provide general procurement and compliance education. They do not give legal advice, classify a hazardous area, select equipment, perform conformity assessment, certify a product or approve an installation. Responsible parties must use current official law, licensed standards, exact product documents, certificate records, site data and competent professional judgement.
Request an evidence-led document review
Send the destination market, area classification, required EPL, exact model and suffix, full marking, current certificates and schedules, circuit data and available instructions. MMAIATEX can organise the available information for review by the responsible procurement, engineering, compliance and site teams.
