An EAC certificate for explosion-proof equipment cannot be confirmed from the product name alone. The decision depends on the equipment itself, the intended gas or dust environment, the protection method, its components and the information shown on its label. It also depends on whether the subject is final equipment, a component, a site zone or an installed system.
The practical route is to identify those inputs first, then compare the product with the certification scope under TR CU 012/2011. ATEX or IECEx documents may be useful evidence, but they do not by themselves establish that mandatory EAEU certification applies. A site does not automatically need the same document for every item installed there.
What the assessment covers
The assessment concerns explosion-protected equipment and the evidence needed to determine its EAEU certification position. It starts with the product, not with a preferred document. The same site may contain complete equipment, separate components and installed systems. These categories should not be treated as interchangeable.
Final equipment is considered as the product that will be supplied for use. A component may have a separate technical role and separate supporting evidence. A site zone describes the environment where equipment is intended to operate. An installed system describes an arrangement in that environment. Each description answers a different question.
- What is the product?
- Where is it intended to operate?
- What gas or dust environment is relevant?
- How does the equipment achieve explosion protection?
- Which components form part of the product or arrangement?
- What information appears on the label?
These points define the starting boundary for the review. They also help prevent a component, site zone or installed system from being assessed as if it were final equipment.
Why the product description matters
“Explosion-proof equipment” is not enough detail for a certification decision. The product description must identify the item being supplied and its intended use. A general catalogue name may cover several configurations, while the certification evidence may relate only to a particular product or arrangement.
State what the equipment is, what it does and what is included in the supplied configuration. Identify the protection method rather than relying on a general statement that the product is suitable for hazardous use. List the components that affect the protection concept. Record the label information exactly as it appears.
The intended environment must be described in practical terms. Confirm whether the relevant environment involves gas or dust. If the equipment can be used in more than one environment, separate those intended uses rather than combining them in one broad description.
What to prepare before the review
Prepare a product file that allows the item and its intended use to be identified without assumptions. The file should be consistent across the product description, drawings, labels and existing Ex evidence.
- Product name and a clear description of the equipment.
- The intended gas or dust environment.
- The stated protection method.
- A list of components included in the product or supplied with it.
- Label information and any identification shown on the equipment.
- Drawings that show the relevant product configuration.
- Available Ex evidence for the equipment and its components.
- Existing ATEX or IECEx documentation, where available.
This list is a preparation guide, not a conclusion that every item is required in every case. Its purpose is to show the product boundary and reveal gaps before a certification route is selected.
Drawings should match the product that will be supplied. If the drawing shows a different configuration from the label or the available Ex evidence, the decision may remain uncertain. The same applies when a component is shown as part of final equipment in one document but treated as a separate item in another.
How the certification decision is made
The decision follows a defined sequence. First, identify the subject of the assessment. Decide whether it is final equipment, a component, a site zone or an installed system. Do not merge these categories simply because they are used together at one location.
Next, define the intended environment. Separate gas and dust applications. Then record the protection method, components and label information. These inputs describe the product in the terms needed for a scope check.
After that, review the certification scope under TR CU 012/2011. The result may show that the product requires an EAEU certification route, that further clarification is needed, or that the original description combined different subjects. The correct outcome cannot be selected by applying one document to all equipment at a site.
Finally, compare the available drawings and Ex evidence with the identified product. This check tests whether the documentation relates to the same equipment, configuration, protection method and components. ATEX and IECEx material should be treated as supporting evidence for review, not as an automatic substitute for the EAEU decision.
- Identify the product and its supply configuration.
- Separate final equipment, components, site zones and installed systems.
- Define the intended gas or dust environment.
- Record the protection method, components and label information.
- Check the relevant certification scope under TR CU 012/2011.
- Compare drawings and Ex evidence with the actual product.
- Confirm the appropriate next document route from the resulting scope decision.
Who provides which information
The overseas supplier provides the product facts. This includes the equipment description, intended use, protection method, component information, label details, drawings and available Ex evidence. The supplier must also identify whether the material relates to the final equipment, a separate component or an installed arrangement.
The certification review uses that information to define the assessment subject and examine the EAEU scope. It can identify inconsistencies between the product, drawings, labels and evidence. It can also distinguish information that supports the assessment from a document that is being incorrectly treated as the final EAEU document.
The site or installation context is relevant to the intended environment, but it does not replace the product description. A site zone should not be used as a substitute for identifying the equipment. Likewise, an installed system should not automatically be treated as the same subject as each component used within it.
This division keeps the decision traceable. The supplier explains what is being supplied. The review tests how that subject fits the certification scope. The resulting route is based on the identified product and evidence, not on a generic hazardous-area label.
What the service delivers
The service is structured to give the supplier a clear certification position based on the supplied product information. It covers product identification, intended environment, protection method, components and label information. It also covers the separation of final equipment from components, site zones and installed systems.
The review identifies whether the available material is sufficient for a scope decision. It checks the relationship between drawings, Ex evidence and the equipment being supplied. Where ATEX or IECEx documents are available, it places them in the correct role within the review instead of treating them as automatic proof of mandatory EAEU certification.
The practical output is a defined next step for the identified product. That may involve confirming the relevant EAEU certification route, resolving an unclear product boundary or requesting the missing information needed to continue the assessment. The route is tied to the item and configuration reviewed.
This approach is useful where a supplier has several related products, interchangeable components or one product intended for different environments. It avoids producing a broad conclusion for a whole site when the actual question concerns one item or one configuration.
How a supplier should choose between product descriptions
Use the narrowest accurate description that matches the equipment to be supplied. Do not describe a complete product as a component merely because it includes components. Do not describe a component as final equipment merely because it will be installed at a site. Record the intended environment separately from the product identity.
For example, suppose a supplier has a complete explosion-protected unit, a replaceable component used inside that unit and drawings for an installed arrangement. The supplier should not submit all three as one “site product”. The complete unit is one assessment subject. The replaceable component is a second subject if it is supplied separately. The installed arrangement is a different description of how equipment is used at the site.
The decision path is therefore to identify which item is being placed on the market or supplied, state whether its intended environment is gas or dust, describe its protection method and list the relevant components. The drawings and Ex evidence should then be matched to that item. If the supplier is asking whether the complete unit needs an EAEU certificate, evidence for the separate component cannot answer that question by itself.
What affects a quotation
A quotation is based on the defined product and the work needed to review it. The main factors are the number of products, the number of configurations and whether the submission concerns final equipment, separate components or installed systems.
The intended environment also affects the review because gas and dust applications must be distinguished. The stated protection method, the number and role of components, and the completeness of label information are relevant. Drawings and Ex evidence require less clarification when they clearly match the product being supplied.
Existing ATEX or IECEx documentation may form part of the evidence review. Its presence does not decide the EAEU route, but it can affect the material that needs to be checked. A quotation should therefore be based on actual documents and product variants, not only on the general description “explosion-proof equipment”.
Before requesting a quotation, group documents by product and configuration. Mark which files relate to final equipment and which relate to components. State the intended gas or dust environment and provide the label information. This gives a more reliable basis for defining the review.
Common errors to avoid
- Assuming that every item at one site needs the same document.
- Using ATEX or IECEx evidence as automatic proof of mandatory EAEU certification.
- Submitting a product name without identifying the protection method.
- Leaving the intended gas or dust environment undefined.
- Combining final equipment, components and installed systems in one product description.
- Providing drawings that do not match the labelled configuration.
- Relying on a general site description instead of identifying the supplied equipment.
These errors make the scope unclear. They can also lead to evidence being reviewed against the wrong subject. Correcting the product boundary at the start is usually more practical than trying to interpret unrelated documents together.
Practical questions
Does every explosion-protected product need an EAC certificate?
Not every product can be assigned the same document from its general description. The decision depends on the identified equipment, its intended gas or dust environment, its protection method, its components and the applicable certification scope. Final equipment, components and installed systems must be separated before the route is confirmed.
Can an ATEX certificate replace EAEU certification?
ATEX evidence does not by itself establish that mandatory EAEU certification applies or that it can be replaced. It can be reviewed as Ex evidence, but the product must still be checked against the relevant EAEU certification scope.
Do IECEx documents remove the need for an EAEU scope check?
No. IECEx documentation may support the technical review, but it does not decide the EAEU route on its own. The equipment, intended environment, protection method, components and label information must still be identified and assessed.
What should I send first for a quotation?
Send the product description, intended gas or dust environment, protection method, component list, label information, drawings and available Ex evidence. Identify which documents relate to final equipment, separate components or an installed system. This allows the quotation to reflect the actual product scope rather than a general site description.
Start with the product boundary, then match the environment, protection method, components, label and evidence before selecting the EAEU certification route.
an Ex junction box with alternate cable glands
Check whether the proposed glands, threads and sealing arrangements match the assessed construction and the intended gas or dust environment. Give the assessment body the revised drawing and Ex marking before relying on the existing evidence.
For equipment covered by TR CU 012/2011, check the certification scope and the approved Ex marking against the equipment, environment and conditions of use. Keep installation and operating limits in the technical file.
Compare the certificate and declaration routes and check what evidence applies to your product.
