▪ Decide the size, direction and the pickup point of the load. These
parameters determine the utilisation of the anchoring.
▪ Characteristic failure loads (N RK or V RK) describe every load that
is reached or exceeded in 95% of all failures (5% fractile).
▪ Permissible loads are working loads that already include an
appropriate material and installation safety factor. These apply only,
if the approval conditions are complied with (N app or V app ).
▪ Recommended loads or maximum working loads include an
adequate load safety factor. These apply only if the manufacturer’s
specifications are complied with. (F rec – valid for all load directions,
N rec or V rec )
▪ The calculation is carried out by dividing the respective failure load
or characteristic loads by a safety factor.
▪ Recommended safety factor compared to the average failure
load.

▪ The specified loads loads apply to individual anchors that are
placed away from the edge, i.e. there is no influence of edges,
corners and other anchors.
▪ The characteristic axis- and edge distances, labelled with C cr,N
and C cr,V , give the distances at which an anchor can have its max.
characteristic load in the material.
▪ The specified minimum axis- and edge distances, labelled with
S min and C min , give the distances where there is no failure of the
building material during the installation of the anchor. The loads
must be reduced in this case → Adhere to the design methods.
