Structural bearings
Structural bearings are components that allow for relative rotation of parts of structural works, transfer loads and permit or prevent displacements in one or more directions. The most common bearing types for use in bridge construction are spherical bearings, cylindrical bearings, pot bearings (with or without sliding part), roller bearings and guide bearings.
For bearings in building construction, non-reinforced or reinforced elastomeric bearings or elastic elements are used.
For vibration isolation of buildings, steel spring elements, elastic elements as well as non-reinforced or reinforced elastomeric bearings can be used. However, the vibration isolation itself is not covered by the approval.
Regulatory framework
DIBt grants national technical approvals (abZ) for bearings. European Technical Assessments (ETAs) can also be issued for these products.
For construction techniques comprising bearings for which there are no conclusive technical rules, DIBt grants general construction technique permits (aBG).
EAD 050004-01-0301 Spherical and cylindrical bearing with special sliding material made of UHMWPE (ultra high molecular weight polyethylene)

National procedure
To prepare an abZ/aBG for your construction product, we need an application from you. We recommend that you contact us prior to doing so. Feel free to send us your enquiry informally via email to dibt(at)dibt(.)de or to the competent technical contact listed in the top right.
For a first assessment, please send us the following information:
- Description of the construction product and its intended field of use
- e.g. material, configuration, number of sizes, variants, dimensions
- e.g. use in walls, ceilings, interior construction, building services
- Description of the construction technique and its field of application
- e.g. design of walls, ceilings, elements, etc., and interaction of components
- e.g. application in foundation engineering, reinforced concrete construction, building insulation; as load-bearing or non-load-bearing component; under static and quasi-static loading; fire exposure; other environmental exposures
- Information regarding impact on regulatory concerns
- in particular structural integrity, fire protection, health and environment protection, sound insulation as well as thermal performance
- Explanation of need for an abZ/aBG
- Do you significantly deviate from the Technical Building Rules?
- Or do neither Technical Building Rules nor generally recognised technical rules exist?
- Contact details
- preferably email address and/or telephone number, as well as name, organisation/company, and postal address
We will then contact you to clarify the next steps.
If you already hold a DIBt approval and/or construction technique permit and wish to apply for an amendment, supplement, or renewal, please use the form provided below.

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.
