Catalysts for firing systems
Catalysts are used in firing systems to optimise the combustion processes and reduce the amount of harmful flue gas substances produced.
In this work area, DIBt grants:
- national technical approvals (abZ) for catalysts that are not covered by the applicable harmonised standards or a European Technical Assessment;
- general construction technique permits (aBG) for the design and execution of the corresponding applications.
National technical approvals and general construction technique permits can be granted together in a single decision ('combined decision').
European Technical Assessments (ETAs) can also be issued for catalysts that are not (fully) covered by a harmonised standard. For construction products covered by an ETA, a general construction technique permit for the application may be pertinent.
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. These are compilations helping to speed up the procedure.
The approval principles and test programmes in this work area are not published, but are made available to the applicants during the procedure. To date, the following compilations are available:
Preliminary test programme for dust separators for firing system (Vorläufiges Prüfprogramm für Staubabscheider für Feuerungsanlagen)
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.
