How do you verify that a fire door is correctly certified before ordering?

To verify that a fire door is correctly certified before ordering, request the CE declaration of performance, the classification report from an accredited test laboratory, and the product’s technical file. These documents prove that the door has been independently tested to EN 1634-1 and classified under EN 13501-2. The sections below walk through each verification step in detail.

What documents prove a fire door is genuinely certified?

A genuinely certified fire door must be accompanied by three core documents: a CE declaration of performance, a classification report issued by an accredited testing laboratory, and a technical file that links the tested specimen to the product being supplied. Without all three, you cannot confirm that the door delivered to site matches the door that was tested.

The CE declaration of performance states which harmonised standard the product is certified under — for fire-resistant doors, that standard is EN 1634-1. It identifies the manufacturer, the product family, and the declared performance characteristics, including the fire resistance classification. This document is legally required for placing a construction product on the European market, but its existence alone does not confirm that the underlying test results are sound.

The classification report is the more technically meaningful document. It is issued by the testing laboratory and summarises the results of the fire resistance test, the scope of direct application (what variations from the tested specimen are permitted), and the resulting classification under EN 13501-2. If a manufacturer cannot supply this report, there is no independent evidence that the door performs as claimed.

The technical file closes the gap between the test specimen and the product. It documents the exact construction of the tested door — materials, dimensions, hardware, seals — so you can verify that the product you are ordering is within the scope of the test. Manufacturers who publish all three documents openly, without requiring you to request them individually, make the specification process significantly more reliable.

Note that for industrial fire doors, two CE marking standards apply simultaneously: EN 16034 (fire- and/or smoke-resisting closing elements) and EN 13241 (industrial, commercial, and garage doors generally). Both are mandatory and should be present in the documentation — they are not interchangeable, and the presence of one does not substitute for the other.

What does the EN 13501-2 classification on a fire door actually mean?

EN 13501-2 is the European standard that defines how fire resistance performance is classified for construction products used in fire-separating elements, including doors. The classification tells you how long a door resists fire under standardised test conditions and which performance criteria it satisfies during that period. The notation always combines a criterion code with a time value in minutes.

The most common criteria appearing in fire door classifications are:

• E (integrity): The door prevents the passage of flames and hot gases for the stated duration.
• W (radiation): In addition to integrity, the door limits radiant heat transfer through the door to a defined threshold on the unexposed face. W is the Dutch standard baseline criterion — in the Netherlands, EW60 is the typical default classification for fire-resistant industrial doors, though other classifications such as EI2-60 are equally valid and common alternatives.
• EI1 and EI2 (insulation): The door limits the temperature rise on the unexposed face. EI1 applies a stricter temperature limit; EI2 permits a higher temperature rise on the unexposed side and is therefore the less strict insulation criterion. These are not interchangeable — specifying EI without the suffix 1 or 2 is technically incomplete and must be avoided.

A classification such as EI2-60 means the door satisfies the less strict insulation criterion for 60 minutes. A classification of EW 60 means the door satisfies integrity and limits radiant heat transfer for 60 minutes, but does not meet the insulation criterion. Which classification is required for a given opening depends on the project-specific fire safety calculation, not a blanket rule. Understanding the difference matters at the specification stage, because substituting one classification for another without checking the fire safety report is a design error with regulatory consequences. If you are uncertain which classification applies to your project, consult a qualified fire safety engineer or contact Metacon-Next directly.

How do you check whether a CE mark on a fire door is valid?

A valid CE mark on a fire door must be backed by a declaration of performance that references a specific classification report. To check its validity, cross-reference the product identifier on the CE label with the classification report number, confirm the testing laboratory is accredited, and verify that the product configuration you are ordering falls within the tested scope.

The CE mark itself is a manufacturer’s declaration — it is not a third-party approval stamp. This means the mark can legally appear on a product even when the underlying documentation is incomplete or the tested scope has been extended beyond what the classification report supports. The verification work falls to the specifier.

Practical steps to validate a CE mark:

1. Request the full classification report, not just the CE label or declaration summary.
2. Check that the testing laboratory named in the report is accredited under EN ISO/IEC 17025 for fire resistance testing.
3. Compare the product dimensions, hardware specification, and construction details in your order against the tested specimen described in the classification report.
4. Confirm the classification report covers the specific fire resistance class (EI1, EI2, or EW) and duration you have specified — never accept a reference to EI alone without the 1 or 2 suffix.
5. Verify that both relevant CE marking standards are covered: EN 16034 (fire/smoke resisting closing element) and EN 13241 (industrial door, general).
6. Check whether the manufacturer holds ISO 9001 certification — this provides assurance that their production process is quality-managed and consistent with the tested product.

Manufacturers who make their classification reports and CE declarations publicly available remove most of this friction. Metacon-Next, for example, publishes its certificates, classification reports, and EPDs openly on its website — an approach that allows architects to complete verification without waiting for a sales response.

What’s the difference between EI1 and EI2 fire doors?

The difference between EI1 and EI2 lies in how strictly the door limits temperature rise on the unexposed face during a fire. EI1 applies the stricter insulation criterion: under EI1, the average temperature rise on the unexposed face is limited to a lower threshold. EI2 is the less strict criterion: it permits a higher average temperature rise on the unexposed side before the classification is exceeded.

In practical terms, an EI1 door provides better thermal protection for people or materials on the side away from the fire. An EI2 door still prevents flames and hot gases from passing through and limits heat to a defined threshold, but the unexposed surface can become significantly hotter before the classification is exceeded.

The choice between EI1 and EI2 is not a preference — it is determined by the fire safety calculation for the specific opening. Some applications, particularly where people may be in close proximity to the door on the protected side, may require the stricter EI1 criterion. Others may not. Specifying EI without the suffix is technically incomplete and creates ambiguity that can surface during permit review or a fire safety inspection. Always confirm which criterion applies with the fire safety engineer responsible for the project before writing it into the specification.

Should you request certification documents before or after placing an order?

You should request and review all certification documents before placing an order — ideally at the specification stage, before the product is even written into the tender. Receiving documentation after ordering creates a situation where design decisions have already been committed to a product that may not match the required classification, dimension scope, or technical constraints of the project.

For architects carrying design responsibility, this is not just a procurement preference — it is a matter of professional liability. If a specified product cannot be verified against the fire safety requirements during permit review, the consequence is either a design revision or a substitution, both of which cost time and credibility.

What to request before committing to a product:

• The current classification report, including scope of direct application
• The CE declaration of performance, covering both EN 16034 and EN 13241 where applicable
• Technical drawings showing installation dimensions, frame depth, and hardware positions
• An EPD (Environmental Product Declaration) if the project is assessed under BREEAM or LEED
• Confirmation that the required opening size falls within the tested and certified scope
• Confirmation of the exact EI1, EI2, or EW classification — not a generic EI reference

Manufacturers who provide this documentation on request — or better, make it available without a request through a product portal or product catalogue — allow specifiers to complete their design file before the tender goes out. This is the standard that serious industrial fire door manufacturers should be held to.

Which certification bodies are recognised for fire door testing in Europe?

Recognised fire door testing laboratories in Europe are those accredited under EN ISO/IEC 17025 for fire resistance testing and notified under the Construction Products Regulation (CPR) as notified bodies (NoBos). Efectis is among the most widely recognised in the Netherlands and across Europe, operating laboratories in multiple countries and issuing classification reports that are accepted by building authorities across the EU.

Other recognised bodies include laboratories operating under national accreditation bodies such as RvA (Netherlands), DAkkS (Germany), COFRAC (France), and UKAS (United Kingdom). The key requirement is that the laboratory is both accredited for the specific test standard — EN 1634-1 for fire resistance of door and shutter assemblies — and notified under the CPR for the relevant product family.

When reviewing a classification report, check:

• That the laboratory is identified by name and accreditation number
• That the accreditation covers EN 1634-1 specifically
• That the report is dated and references the product tested, not a generic product family
• That the classification code specifies EI1, EI2, or EW — not a generic EI reference

For projects outside the Netherlands, it is worth confirming whether the destination country applies additional national requirements beyond the CE marking framework. Some countries — including Germany, France, Switzerland, and Austria — have supplementary national certification requirements for fire doors. Manufacturers who have conducted additional testing to meet these country-specific requirements provide a significant practical advantage for cross-border projects. The Metacon-Next product range has been tested to meet requirements in several of these markets, which reduces the documentation burden for international specifications.

If you are specifying fire-rated industrial doors and want to confirm that the product, its classification reports, and its installation scope match your project requirements, the most direct route is to contact Metacon-Next directly or request a project-specific quotation — with full documentation provided as standard, not as an afterthought.
