Masonry made of masonry units bearing the CE marking
Masonry is made from masonry units bound by mortar or other bonding agents and possibly other accessories. Different techniques are used to produce masonry for different application areas.
In many cases, the masonry units used for the erection of the masonry are covered by the harmonised standard series EN 771.
Depending on the application area, requirements relating to stability, health and environmental protection, thermal and sound insulation and/or fire safety may apply to the masonry.
For the design and execution of masonry, the Technical Building Rules apply; cf. MVV TB, Part A 1.
DIBt grants general construction technique permits (aBG) for construction techniques for which DIN EN 1996 in conjunction with the National Annexes and the associated national application standards do not contain conclusive technical rules or which significantly deviate from the provisions set out therein. For example, not all unit geometries (hole patterns, special factory-made units) or masonry unit/mortar combinations are described in DIN EN 1996.
If you wish to CE-mark masonry units which are not (fully) covered by the harmonised standards (EN 771), DIBt can issue a European Technical Assessment (ETA) for this purpose.
Please also see Other masonry.
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.Form for requesting a European Technical Assessment (ETA) (2 pages)
