Validating a Hardware Certificate 2026: The Seven Parts, DoP and CE Marking, and the Six Red Flags

Almost nobody checks a certificate. It arrives as a PDF with a logo, it satisfies the line on the submittal, and it is filed.

That is why the bad ones work. Not because they are sophisticated forgeries — almost none are — but because they are never opened by somebody looking for the seven things below.

The seven parts of a genuine test certificate

Six of those seven are usually present on any real document. **The one most often missing, and most often the one that matters, is the scope of application** — the range of sizes, materials, frame types and hardware sets the result extends to.

A certificate without a scope is a result for one object. With a scope, it is a result for a family, and your product is either inside that family or it is not.

Accreditation is not certification, and the difference is who watches

These two words are used interchangeably in sales conversations and they mean different things.

**Certification** is a body stating that a product meets a standard. **Accreditation** is a higher-level authority stating that the certifying body is competent to make that statement — through an audit of its methods, equipment and staff.

A certificate from an unaccredited body is a statement by an organisation that nobody has checked. It may be perfectly sound. It is not evidence in the sense a specification means, and a reviewer who knows the difference will treat it as a letter.

So the useful question is not "is it certified" but **"who accredits the body that certified it, and what is the accreditation number"**. A genuine certificate carries that on its face.

CE marking and the Declaration of Performance

For construction products in the European system — and door hardware covered by harmonised standards such as EN 1125, EN 179, EN 1154, EN 1935 and EN 12209 is in that system — the manufacturer issues a **Declaration of Performance** and applies the CE marking.

That structure is worth understanding because it changes what you should ask for.

The DoP is the manufacturer's declared performance against the harmonised standard, backed by testing carried out or assessed by a **notified body** — an organisation designated by a member state for that purpose, with a four-digit identification number.

So on a CE-marked product there are three things to look for, and they connect: the CE mark itself, the notified body's number, and the DoP that states the declared classification. A CE mark with no DoP behind it is a sticker.

The UK operates a parallel arrangement with UKCA marking and approved bodies. Other markets have their own systems, and a certificate from one is not automatically evidence in another — the same point our fire door page makes about EN 1634-1 and UL 10C.

How to check a certificate independently, in five minutes

**Find the issuing body's own register.** Most certification bodies publish a searchable list of current certificates. That is the authoritative source; the PDF you were sent is a copy.

**Search by the certificate number, not by the company name.** A company name will find the company. A number finds the specific document, and its absence from the register is the answer you were looking for.

**Check the scope against your product.** Your model, your size, your configuration. This is where most honest mismatches are found — not fraud, but a real certificate that covers the 900mm leaf and not the 1100mm one.

**Check the date.** Certificates lapse, and are reissued with different numbers. An out-of-date certificate is not evidence of current compliance even if the product has not changed.

**Ask for the test report, not only the certificate.** The certificate is a summary; the report is the evidence. A supplier who can produce the report has one, and a supplier who cannot may be holding a certificate issued to somebody else.

The six red flags

**A logo with no number.** A certification body's mark on a datasheet with no certificate number behind it is decoration. This is the commonest one by a wide margin.

**A certificate in a name that is not the supplier's.** Certificates attach to the manufacturer of the tested product. A trading company forwarding a factory's certificate should say so and name the factory; one that presents it as its own is telling you something about how it operates.

**"Tested to" rather than "certified to".** Tested to a standard can mean an internal test following the method. It is not the same claim, and the wording is usually chosen deliberately.

**A scope that does not mention your size or configuration.** Covered above, and the most common legitimate failure.

**A certificate for a "series" or "range".** Sometimes genuine and defined in the scope; often a way of extending one tested model across a catalogue. Check whether the scope lists the models or describes a family by dimension.

**A refusal to provide the report.** The certificate exists or it does not, and the report either exists or the certificate is worth asking harder questions about.

Initial type testing, FPC and why a certificate can go stale without anything changing

A certificate is a photograph of a product at one moment. Two mechanisms are supposed to keep it true afterwards, and knowing their names makes a supplier's answer much easier to assess.

**Initial type testing** is the test itself — the sample went to a laboratory, was tested against the standard, and a result was recorded. That is the event the certificate describes.

**Factory production control** is the ongoing part: the manufacturer's documented system for ensuring that what leaves the line today still matches what was tested. Under the European construction products system, FPC is audited, and a certificate for those product families references it.

That distinction explains something buyers find puzzling. A product can be genuinely tested and still drift — a supplier changes a sub-component, a plating line, a casting source — and the certificate does not automatically become false, but it stops describing the product accurately.

So on a long supply relationship the useful question is not only "do you have a certificate" but **"has anything in the tested configuration changed since it was issued"**. An honest supplier has a record of what changed and when, because that record is what FPC is.

What to ask when a project needs evidence you have not been given

The situation is common: a specification names a classification, the supplier has not offered a certificate, and nobody wants to be the one to ask badly. Four sentences cover it.

"Which standard and classification does this model hold, and what is the certificate number?" — a single question that a supplier either answers with a number or does not.

"Which body issued it, and who accredits them?" — the accreditation question from earlier on this page.

"Does the scope cover this size and configuration?" — quote your leaf size, your frame type, your hardware set.

"Can we have the test report as well as the certificate?" — the request that separates a holder from a forwarder.

If the answer to the first is that the product is not certified, that is a usable answer and often the correct one for the application. The failure mode is not an uncertified product; it is an uncertified product described as though it were certified, which is what the six red flags above are all detecting.

What we hold, stated plainly

Where one of our products has been tested and a certificate exists, the product page names the standard, the classification and the scope, and the certificate is available on request. Our documents page lists test documents as on-request rather than published, and that is literal: we send what exists for the exact models you ask about.

**Our 307 and 311 exit devices are in testing.** Until certificate numbers exist, nothing we publish will imply they hold a fire rating, an ANSI grade or a UL listing — not in a description, not in a comparison, and not by placing a standard's number near a product that has not been tested to it.

We also do not reproduce another manufacturer's certificate to describe our own product. A certificate belongs to the assembly it was issued for, and borrowing one is the same category of error as inventing a dimension — which is the argument our dimensional pages make, applied to paper.

Why a supplier should welcome the check

The five-minute check above is sometimes read as distrust. It is the opposite: it is the only thing that makes a genuine certificate worth more than a confident sentence.

A factory that holds real evidence loses nothing when a buyer verifies it, and gains the one thing that cannot be claimed — a buyer who has checked. A factory that does not hold it is the reason the check has to exist.

So ask, and expect the register entry. It costs the supplier nothing and it is the cheapest due diligence in the whole procurement.
