A. Partial safety factors

App.E
A 100   General

App.E A
101
   Partial safety factors depend on the safety class and the failure type. The partial factors are available for five different levels.

App.E A
102
   The selection of the levels is given in Table A1 for the ultimate limit state.

App.E A
103
   The recommended selection of the levels for the serviceability limit state is given in Table A2.

App.E A
104
   Factors for each level A, B, C, D and E are given in the following:
