Technical Approval

The technical approval (ATG) provides a technical opinion, including a description and the technical properties. An ATG is a favorable assessment of one particular construction product from one manufacturer for a well-defined application. It is intended for innovative products and building systems for which no or insufficient standards exist. This ensures that these products and building systems are suitable for use, can be used or installed without risk and are of good quality. All this according to the rules of the art of the Belgian market.

The advantages of an ATG certificate for consumers

An ATG label allows the user to check the conformity of the products delivered to the construction site with the existing approval. Since ATG certificates are issued for products and systems for which no product standards exist (yet), this is the only way to see if the products are approved.

Innovations in the construction industry are important to be more efficient in the long run. ATG certification ensures that construction sites do not become laboratories to test out those innovative ideas and thus customers are protected.

Who gets the ATG certificate?

In principle, an ATG is delivered on the basis of an approval guideline. Such guidance is prepared by experts of the Belgian Union for Technical Approval in Construction (BUtgb) and forms an assessment basis for construction products.

On top of this, there is usually certification, which means that a certification body mandated by the BUtgb carries out external supervision of the conformity of production with the published approval at a set frequency. This review or control is described in a convention drawn up when the ATG is granted. This convention specifies how the manufacturer organises his own production control and which external tests will be carried out.

ATG certification allows companies like AquaConsult to apply non-traditional products and techniques without danger.
