Attestation of Conformity
Attestation of Conformity (AoC) is an assessment of compliance of relevant characteristics of a construction product with a corresponding technical specification pursuant to defined methods and systems. The systems consist of a combination of methods. Some methods are applied by a manufacturer himself, while others by an Approved (Notified) Body.
Depending on which of the six essential requirements for construction works are relevant for a construction product, one or several of the AoC systems 1+, 1, 2+, 2, 3 or 4 is/are applied. The most stringent system is the 1+, where the involvement of the Approved Body in the process of AoC is the highest. Any other system requires less involvement of the Approved Body in the process. For non-safety critical products, the AoC usually involves a manufacturer’s declaration only with no third party involvement (the system 4). The systems are applied as stand-alone, or in a combination of several as so called cumulative systems in cases when the subject of the conformity attestation are characteristics of different levels of risks presented after incorporation of the product into works. The result of the conformity attestation pursuant to the European technical specifications (harmonised EN or ETA) is the CE marking. If the product is not covered by any of the European technical specification, however the product is listed in the Ministerial decree of Slovak republic no. 558/2009 Coll. on construction products, then the conformity is declared pursuant to a national technical specification (STN or technical approval) and the product is labeled with the CSK mark.
The Institute carries out conformity attestations in the scope of the authorization (AB SK04) and notification (NB 1301) by product certification (systems 1+ and 1), certification of factory production control (systems 2+ and 2) and by mere testing (system 3).
In addition, where manufacturers wish to add credibility or they have limited test facilities, the Institute as an accredited test laboratory also carries out tests, that are normally in their responsibility. This applies especially when the AoC systems 2+, 2 and 4 are applied.
