1. 3.2.1Division 3.2.1
2. 3.2.2The first assessment step shall verify whether the observed safety performance is complying with the NRV or not. The observed safety performance shall be measured by using the measurement units listed in Appendix 1 and the data referred to in section 1.1, with time series which shall include the most recent years of observations as specified in section 3.1. The observed safety performance shall be expressed in terms of:
3. 3.2.3The second assessment step shall consider the safety performance as acceptable if the MWA does not exceed the NRV plus a 20 % range of tolerance. If this condition is not satisfied, the Agency shall ask the safety authority of the Member State concerned to provide the specifics of the single highest-consequence accident (in terms of FWSIs) in the most recent years of observation as referred to in section 3.1, excluding the years used to set the NRV.
4. 3.2.4Division 3.2.4
5. 3.2.5The fourth assessment step shall verify whether the number of significant accidents per train-km, with respect to the previous years, remained stable (or decreased). The criteria for this appraisal shall be whether there has been a statistically significant increase in the number of relevant significant accidents per train-km. This shall be evaluated by using an upper Poisson tolerance bound which will determine the acceptable variability based on the number of accidents that occurred in the different Member States.
