What is an attestation?

An attest is proof that the building product or system in its application can comply with Dutch building regulations. The conditions in the attest describe the way the building product or building system must be processed and/or assembled.

With an attestation examination, SKG-IKOB assesses the performance of the building product or building system. If necessary, we carry out calculations and/or tests. With this examination, we determine the performance of the product or system and under which conditions it can deliver the performance. At least every five years we assess whether the statements in the attestation are still correct.
