For National Technical Approvals (abZ) or General Construction Technique Permit (aBG) the Fraunhofer IGP is recognized by the Deutsches Institut für Bautechnik DIBt (technical authority in the construction sector) as a Testing, Inspection and Certification Body according to the State Building Codes.

For approvals with numbers Z-14.1-… and Z-14.4-… (connecting elements), the Fraunhofer IGP is recognized as Inspection and Certification Body since 2014. The notification was successfully extended to subjects with approval numbers Z-30.6-… (welded components of steel) and Z-14.9-… (structural anchorings of attachment points for anchor devices) in 2018. In addition, the recognition was extended for the approval group “Components of structural steel welded by using standardized process with special application” (approval number Z-30.6-…) as Germany’s first and currently only notified Testing Body.

The Fraunhofer IGP takes on external monitoring and certification orders (ÜZ system) in Germany as well as international. The functions of the Inspection Body thereby comprise the inspection of the manufacturer on site with respect to the personnel and technical requirements for a consistently correct manufacturing. The Inspection Body is also responsible for auditing the factory production control to ensure the proper product properties. Thus, the external monitoring comprises inspections of construction products regarding the compliance with the underlying technical approval.

The Certification Body performs the final assessment of the monitoring reports submitted by the Inspection Body with regard to issuing, renewal or revocation of the Certificates of Conformity. If the assessment result is positive, the manufacturer is entitled and obligated to mark the concerning construction products with the national conformity mark (Ü symbol).

For certain construction products or construction techniques, the declaration of conformity can be made by the manufacturer (ÜHP system). In that case, the Testing Body of the Fraunhofer IGP can carry out an prior test of the construction product or construction techniques for conformity with the requirements of the underlying approval (abZ/aBG).
