Declarations of conformity, product and conformity certificates

Certificates / declarations of conformity / marking precast concrete parts

Wherever European regulations are applied, precast concrete parts are, as building products, to be marked with a declaration of conformity and CE mark. If European regulations do not apply, but national German regulations do, the building products must be labelled with the Ü mark.

The labels, declarations and certificates prove that the respective regulations and standard requirements, which concern the prefabricated part or its production, have been observed.

The Ü mark is provided on the basis of conformity certificates and product certificates, the CE mark and the issue of the declaration of conformity by the manufacturer based on a certification of the company’s own in-house production control and products.

In our case, these external certifications are provided by Güteschutz NRW. The certificates continue to apply as long as no quality deviations are observed by Güteschutz during the semi-annual monitoring of production and the in-house production control, which could otherwise lead to a cancellation of the certificates.
