Multiple attachment of non-load-bearing systems in concrete (for all load directions)

The partial safety factors of the resistances regulated in the approval and a partial safety factor of the effects of Y_F = 1.4 have been taken into account. Please refer to the European Technical Approval Guidelines (ETAGs), Appendix C, for information on combining tensile and transverse loads, edge influence and groups of anchors.

Permissible load when exposed to fire

The partial safety factors for load-bearing capacity on exposure to fire of Y_M,fi = 1.0 as recommended in the approval and the partial safety factor of the effects of Y_F = 1.0 have been taken into account.

Nominal drill diameter and drill cutting diameter

Carbide masonry drills must comply with the specifications set out in the code of practice of the Deutsches Institut fu00fcr Bautechnik (German Institute for Building Technology) and the Fachverband Werkzeugindustrie e.V (Professional Association of the Tool Industry) on the "Characteristics, requirements and tests of masonry drills with cemented carbide cutting bodies used for producing drilled holes of dowel anchorings". Wu00fcrth hammer drill bits meet the specifications set out in the code of practice.
