In this paper the statistical assessment of the models that ensure the safety of the reinforced concrete slabs is fo cused. The investigation results in choosing the best mo del as the one that can aspire to become normative for European Union after 2020. Authors dispose with a suffi cient number of data yielded from experimental tests. Ha ving input geometrical and physical parameters of each experiment at hand, the corresponding theoretical value is computed by using three formulas provided by three models involving the same inputs. Case by case, the ratio between measured and theoretical value reveals the safety immediately. This ratio stands as the one parametric dimensionless statistical variable which is analysed after wards. Due to statistical parameters evaluation and in accordance with engineers a new model was suggested, statistically verified and nominated as the normative one.
