How to Speed Up ATEX Certification Without Risk
Introduction
For manufacturers of explosion-proof equipment, ATEX certification is often seen as a bottleneck, complex, time-consuming, and costly when delays occur.
Yet, speeding up the process without compromising compliance is not only possible, it’s a strategic advantage.
In highly competitive industries, reducing time-to-market while ensuring full compliance with the ATEX Directive (2014/34/EU) can significantly impact the:
-
revenue;
-
project timelines; and
-
customer trust.
This article explains how to accelerate ATEX certification safely, based on real-world experience from notified bodies like ConformEx.
Impact of faster ATEX certification on business
Speeding up certification isn’t just a technical advantage, it’s a commercial one:
-
Faster time-to-market
-
Reduced engineering rework costs
-
Improved project planning reliability
-
Stronger competitive positioning
In industries where delays can cost contracts, efficiency becomes a key differentiator.
Why ATEX certification delays happen?
Before improving speed, it’s essential to understand the root causes of delays:
-
incomplete or inconsistent technical documentation leading to non-compliance and multiple revision cycles;
-
design issues which are identified late in the assessment process;
-
misinterpretation of protection concepts (Ex d, Ex e, Ex i, etc.);
-
lack of early communication with the notified body;
-
failure to submit product samples for testing in a timely manner.
The above-mentioned issues don’t just leading slow certification, they increase also costs and risk project deadlines.
1. Involve a notified body early
One of the most effective ways to speed up certification is notified body early engagement.
Why it matters?
Waiting until the design to be finalized, often leads to major re-designs to correct the non-compliances which will be found by the notified body during review or technical documentation and also testing.
What is the best practice?
Engage your selected notified body soon and during:
-
Concept design
-
Risk assessment phase
-
Protection method selection; and specially during
-
drawings prepartion and material selection
👉 Early feedback from the notified body, will help you to avoid costly corrections later and will streamline the entire process.
2. How could you choose a certification body?
the most important criteria, are required technical capacity and, more importantly, agility and timely response of notified body, which nowadays is considered as the main trouble and challenge of most explosion-proof equipment manufacturers.
Not all notified bodies offer the same level of efficiency and technical support.
What should you look for?
-
agility, timely response and ability to provide early guidance;
-
Strong technical expertise;
-
Industry-specific experience;
-
Clear communication and responsiveness;
An experienced and quick response partner like ConformEx, can help manufacturers avoid pitfalls and accelerate certification without compromising compliance.

3. First and foremost, choose the appropriate protection concept and other explosion characteristics contained in the ATEX marking
Selecting the wrong protection method can cause major delays.
Common mistake: Choosing the protection mode(s) without fully understanding its implications that will lead to fault.
The solution is to do the followings, early:
-
learn the concept and application of explosion-proof protections. click here
-
understanding the principles and relation between Ex zones, Categories,protections and EPLs. click here
-
understanding and determining the intended zone of use (Zone 0, 1, 2 / 20, 21, 22) or product category. click here
Note: for zone selection, the main consideration and attention should be paid to the needs and requirements of the product buyer and user.
-
Type of equipment
-
other explosion protection relevant characteristics, are explaind in ATEX marking structure.
👉 A well-chosen protection concept simplifies testing and documentation.
4. in-compliance Product design
Trying to resolve non-conformities in product design and “adapt” it to requirements of the applicable standard(s) at the end, is inefficient and risky.
Instead:
Design your equipment with ATEX requirements integrated from the start.
Focus on:
-
Correct material selection
-
Temperature classification
-
Ignition source analysis
-
Proper sealing and enclosure design
👉 A compliant design from day one avoids multiple redesign cycles.
5. Ensure complete and structured documentation
Incomplete documentation is one of the biggest causes of delays.
Key documents to prepare:
-
Technical file (drawings, BOM, specifications);
-
Risk assessment based on the applicable requirements of the EN or IEC standard relevabnt to the protection type(s) of the product;
-
Explosion protection concept;
-
Test reports (if available);
-
Quality system documentation (for modules D and E of ATEX directive).
Pro tip: structure your documentation clearly and consistently with assisting:
-
an ATEX technical expert who is qualified for you product type and also its applicable explosion protection(s), as well as
-
an expert for quality management system who is qualified for IEC 80079-34.
This reduces review time significantly.
Note 1: finding and hiring full-time staff can be very difficult and costly, so the most economical and quickest method is to ask the notified body for introducing qualified consultants for your product certification and also your quality system certification.
Note 2: if there is an expert in your organization who is somewhat familiar with the applicable requirements of explosion protection type(s) applicable to the product in question, he may follow the content of the Guideline for preparation product technical file, for preparation product technical file for the purpose of for ATEX certification for module B or G.
Note 3: if your organization has previosuly obtained a valid ISO 9001 certificate and also there is a quality management system expert within your organization, he may follow the content of General practical guide for preparation the needed documents for ATEX quality assurance system, for the purpose of for ATEX certification for module D or E.
6. Maintain Clear Communication
Poor communication leads to misunderstandings and delays.
Best practices:
-
assign a dedicated technical contact;
-
respond quickly to review comments; and
-
clarify uncertainties early.
👉 Certification is a collaborative process;
👉 efficient communication speeds everything up.
7. Align Testing and Certification Activities
Testing delays often impact certification timelines.
Optimize it by:
-
Planning tests conducting in parallel and simultaneously with documentation preparation;
-
request the notified body and emphasize to state the name of the lab in which the product is intended to be tested, and also specially the duration of conducting whole tests even approximately, in the certification quotation.
-
preparing the test sample(s) ontime is one of the most important points; and
-
ensuring test samples (prototypes) to be in complaince with the final design of product;
8. Conduct a pre-assessment
A pre-assessment by the notified body can dramatically reduce certification time.
what does this include?
-
to identify gaps in technical documents and quality management system documents, against the requirements, before formal submission;
-
to highlight non-compliances, early;
-
to provide actionable recommendations.
Result: very fewer revision cycles and faster approval during formal assessment and certification.
