FIS VS Plus LOW SPEED) have to be considered. For determination of the installation parameters (minimum concrete cover distances, etc.) as well as required transverse reinforcement see EN 1992-1-1 and general installation rules of the assessments. ¹) The partial safety factors for resistance taken from the European standard EN 1992-1-1 as well as a partial safety factor for action of γL = 1.4 are considered. ²) With FIS EM Plus, FIS SB or FIS V Plus and FIS V Plus LOW SPEED post-installed Rebar anchors are approved in dry or wet concrete with temperatures up to +50 °C (resp. short term up to +80 °C) and drill hole cleaning in accordance with ETA. ³) The ETAs for FIS EM Plus, FIS SB, FIS V Plus and FIS V Plus LOW SPEED permit post-installed rebar connections in concrete C12/15 up to C50/60. The above mentioned basic value for anchorage length changes depending on the relevant concrete strength class. 4) Basic value of the anchorage length in accordance with EN 1992-1-1, section 8.4.3 for concrete strength class C20/25 and good bond conditions. 5) For utilisation of the full steel capacity.
