Regulation (EU) No 305/2011 · Annex III ·In force — and repealed in 2040

What a construction product declares about its performance

A construction product covered by a harmonised standard, or conforming to a European Technical Assessment issued for it, must be covered by a declaration of performance when it is placed on the market. Annex III sets out the model. This free generator follows its twenty lines in the words of your language's own Official Journal text, and it does not decide what your product's performances are.

The product and who declares it

Declaration number

1. Unique identification code of the product-type:

2. Intended use/es:

3. Manufacturer:

4. Authorised representative:

5. System/s of AVCP:

Harmonised standard or European Technical Assessment

Fill 6a or 6b, whichever your product runs under. The model prints both headings because it serves both routes; a product runs under one of them.

Which route

6a. Harmonised standard:

Notified body/ies:

6b. European Assessment Document:

European Technical Assessment:

Technical Assessment Body:

Declared performances

7. Declared performance/s:

The three column headings below are ours, not the annex’s. Item 7 of the model is a single line; the instructions — which the annex says are not part of the declaration — are what describe a table.

Essential characteristic Declared performance Harmonised technical specification

NPD — No Performance Determined — is what the instructions require where no performance is declared for a characteristic. The button fills it.

8. Appropriate Technical Documentation and/or Specific Technical Documentation:

Who signs it

Signed for and on behalf of the manufacturer by:

Place and date of issue

The declaration

This is not a declaration of conformity, and the difference is the whole point. A declaration of conformity says a product meets requirements. Annex III says something narrower and stranger: “The performance of the product identified above is in conformity with the set of declared performance/s.” What you vouch for is that the product performs as YOU have declared — so a declaration whose declared performances are modest, or mostly NPD, is a valid declaration. It is the market, the national rules for the works, and the specifier who decide whether those performances are good enough. This document does not.

Levels and classes go in the declaration itself. The instructions to Annex III forbid describing performance “solely by inserting a calculation formula to be applied by the recipients”, and require that levels or classes presented in reference documents be reproduced in the declaration. A DoP that points at a standard instead of stating the number is the most common way this document goes wrong, and it is the one this page cannot stop you doing — only tell you not to.

Three things on this page are ours, not the annex's. The column headings of the performance table, the NPD button, and this note. Item 7 of the model is one line — “Declared performance/s:” — and everything about how to fill it comes from the instructions, which the annex says are not part of the declaration and should not be enclosed with it. So the table is a reading of those instructions rather than transcription, and it is marked as such.

This model has a sunset, and it is later than you would guess. Regulation (EU) 2024/3110 applies from 8 January 2026 and repealed most of Regulation (EU) No 305/2011 on that day — but not this. Articles 4 to 9 and Annexes III and V survive until 8 January 2040. What remains of the old Regulation today is the declaration of performance and the machinery around it, and nothing else.

The two regimes run in parallel, per product family. The new Regulation does not switch on for a product on a date: its obligations apply to a product family only one year after an implementing act makes a harmonised technical specification mandatory for that family — and a manufacturer may opt in earlier. Until that happens for yours, the declaration on this page is the one your product needs.
