National Technical Approvals ("abZ")

A National technical approvals ("abZ") - commonly referred to as a DIBt approval - is required by the Deutsches Institut für Bautechnik (German Institute for Construction Technology) for all anchorage devices and fall arrest systems designed for permanent installation on a building structure. According to the DIBt, such devices are considered to be part of the building. This applies to anchorage points for individuals as well as lifeline systems and rail safety systems. To date, however, roof safety hooks have been excluded from this rule. The approval is intended to guarantee that the device is reliably connected to the subsurface on which it is installed. In as far as an anchorage device has not been awarded National Technical Approval, this may only be installed when consent has been individually provided. An application to this effect must be submitted to the responsible building authority.

Anchorage devices with National Technical Approval

Meanwhile, a large selection of approved anchorage points is available. This applies to anchorage points for individuals (anchors) as well as traversable lifeline systems. A Ü symbol (abbreviation of Übereinstimmungszeichen = mark of conformity) shows that a fall arrest system has been approved and must be included on the product. This mark confirms that the installed anchorage device - or device to be installed - conforms with that approved by the DIBt - i.e. that all parts are constructed in an identical manner using the same materials.

One approval for several anchors

As a rule, each manufacturer is awarded an approval in which all the approved products are listed. The respective installation method, which has been tested and approved, is also documented in this approval. The installation must be carried out in accordance with these installation instructions, otherwise, the abZ will lose its validity. The approval must be easily accessible and is presented to the building owner. Abbreviating such an approval - or merely providing an excerpt - is strictly prohibited. For greater transparency, some companies also put their abZ on their website.
