Three different documents, three different jobs
A fire resistance test to BS EN 1634-1 produces a test report: what the specimen was, how it was installed, and what happened over time. A smoke leakage test to BS EN 1634-3 does the same for smoke. Neither report gives you a classification on its own.
A classification report to BS EN 13501-2 takes those results and expresses them as a classification — integrity, insulation, radiation, and the smoke and self-closing designations where they apply — together with a field of application. Extended application reports under the BS EN 15269 series widen that field of application by reasoned assessment rather than by further testing.
The field of application is the real boundary
It is tempting to treat the classification as the answer: the doorset is EI 30, and that is that. The classification is only meaningful within the field of application stated alongside it — the range of leaf sizes, constructions, frame types, supporting constructions, hardware and glazing to which the result may be applied.
Every product you sell should sit inside the field of application of the evidence you rely on. Where it does not, you need a further test, an extended application assessment, or a narrower claim. This is the most consequential evidence error in the sector, and it is invisible unless the field of application is recorded as data rather than left in the body of a PDF.
The BS 476 national classes are being retired
A great deal of UK fire-door evidence was generated to BS 476-22, and the familiar FD30 and FD60 designations come from that tradition rather than from the European classification system. On 2 September 2024 the government confirmed it would remove the national classes — the BS 476 series — from Approved Document B in England, leaving BS EN 13501 as the single classification route.
Reaction to fire and roofs were given a six-month transition, which ran out on 2 March 2025. Fire resistance was given five years, taking it to 2029. That is a building-regulations change in England rather than a construction-products one, but for a fire-door manufacturer the practical effect is a deadline: evidence that exists only as BS 476 fire resistance testing has a known shelf life in specifications that follow Approved Document B.
Do not conflate the two systems
Older evidence is not worthless, but it is not interchangeable with a BS EN 13501-2 classification. Where you hold both, record them as separate evidence with separate scopes, and be explicit about which claim rests on which. A doorset described as "FD30 / EI 30" without saying which report supports which designation is making two claims with one piece of evidence.
What a test report is not
A test report is not an approval, a certificate, or a statement that a product may be sold. It describes one specimen on one day. Its value for your product range comes entirely from the classification and field of application built on top of it, and from your ability to show that what you manufacture still matches the specimen that was tested.
