abZ & DIBt

DIBt (DIBt approval)

The German Institute for Construction Technology (DIBt) is responsible for setting down the provisions of the national technical approvals (abZ) for anchorage points and fall arrest systems designed to be permanently installed on a building structure - whatever the method used to install the system. The DIBt requires an examination to be carried out of all the respective anchorage devices to confirm the robustness of the connection with the installation surface.

A ruling of the European Court of Justice (ECJ) of 21 October 2010 (Case C-185-08) provides the legal basis for these DIBt requirements. This ruling defines which anchorage points are classified as personal protection equipment in line with PPE Directive 89/686/EEC and which are classified as construction products according to Directive 89/106/EEC. The so-called "Ü sign" on a product certifies that this product has received national technical approval and also indicates that it must be examined once a year to ensure that it complies with the requirements contained in the DIBt approval for this product.

National technical approval does not replace certification in accordance with EN 795 but should be viewed as a supplementary approval. Licence number Z-14-9-688 which was granted to ABS Safety can be used as an example to illustrate the structure of an abZ awarded by the DIBt and what it contains.
