Requirements for redundant fastening The definition of redundant fastening according to Member States is given in the EAD 330747 § 1.2.1. In Absence of a definition by a Member State the following default values may be taken.

Minimum number Minimum number of anchors per Maximum design load of action of fixing points fixing point NSd per fixing pointa) 3 1 2 kN 4 1 3 kN a)

The value for maximum design load of actions per fastening point NSd is valid in general that means all fastening points are considered in the design of the redundant structural system. The value NSd may be increased if the failure of one (=most unfavourable) fixing point is taken into account in the design (serviceability and ultimate limit state) of the structural system e.g. suspended ceiling.
