¹⁾ The partial safety factors of the resistances regulated in the approval and a partial safety factor of the actions of Y_F = 1.4 have been taken into account. Please refer to the European Technical Approval Guidelines (ETAG), Appendix C, for information on combining tensile and transverse loads, edge influence and groups of anchors. ²⁾The concrete has normal reinforcement. Higher values are possible for higher concrete compressive strengths. ³⁾ Compliant with approval if screws and threaded rods with acceptance test certificate 3.1 in accordance with EN 10204:2004 are proven to be the required material and to possess the mechanical properties stipulated in ETA-10/0255. ⁴⁾ Type S: If a lower fixture thickness is required, make a deeper drill hole accordingly.
