Construction products detail

For the assessment of the above-mentioned construction products and techniques within the framework of the national procedures, DIBt prepares application-specific test plans. DIBt approval principles and preliminary test programmes form the basis for this.

The approval principles and preliminary test programmes are no conclusive technical rules, but rather compilations helping to speed up the procedure. They are not published, but are made available to the applicants during the approval or permit procedure.

The following preliminary test programme has been prepared up to now:

Preliminary test programme for flue gas heat exchangers for completing or retrofitting of firing systems with non-room-sealed heating appliances (Vorläufiges Prüfprogramm für Abgaswärmeübertrager zur Komplettierung von /oder zum nachträglichen Einbau in Feuerungsanlagen mit raumluftabhängigen Feuerstätten)

National procedure

A national technical approval (abZ) and/or oder general construction technique permit (aBG) is granted upon application (see Model Building Code (MBO), Sections 16a(2) and18(2) and (4)). This also applies to amendments and supplements to, or renewals of existing approvals and/or construction technique permits.

No formal requirements apply. The following information is needed: name and address of the applicant, description of the product and/or construction technique and its field of use or application, type of decision required (new decision, amendment or supplement to, or renewal of, an existing decision).

European Technical Assessment (ETA)

To start the ETA procedure, please submit the form below. We will then check if the prerequisites for issuing an ETA are met, i.e., in particular, if the product is not fully covered by an existing harmonised standard. If the prerequisites are met, we will check whether a European Assessment Document (EAD) covering the requested assessment scope already exists or still needs to be developed. If an EAD needs to be developed or amended, a complete technical file needs to be established before the procedure can begin.
