Recommended minimum values for p at ultimate limit states are given in Table 2.4, for reference periods of 1 year and 50 years.

A design using EN 1990 with the partial factors given in annex A1 and EN 1991 to EN 1999 is considered generally to lead to a structure with a p value greater than 3,8 for a 50 year reference period (Table 2.3), i.e. with a rough probability of attaining the ULS in 50 years of 7,210-5 (Table 2.3).
