This Technical Report defines assessment methods for transitions, considered as the linkage between safety barriers or between
safety barriers and removable barrier sections defined by CEN/TS RBS.
This Technical Report also defines assessment methods for connection-transitions to terminals and crash cushions.
Road Authorities and regulatory authorities are free to determine assessment methods, values, measurements etc. and to fix the
details of the requirements.
Assessment methods and design rules can also be utilised in connection to evaluation of changed versions.

This document defines the accuracy, credibility and confidence in the results of virtual crash test to vehicle restraint systems through the definition of procedures for verification, validation and development of numerical models for roadside safety application.

This document specifies requirements for the impact performance of systems designed for the reduction of impact severity for PTW riders impacting safety barriers whilst sliding along the ground, having fallen from their PTW vehicle. The protection systems concerned are those fitted to barriers or barriers that have an inherent PTW rider protection or risk reduction capability. This document excludes the assessment of the vehicle restraint capabilities of barriers and the risk that they represent to the occupants of impacting cars. The assessment of barrier performance with respect to impacting vehicles is covered by EN 1317-1 and EN 1317-2.
This document defines performance classes taking into account rider speed classes, impact severity and the working width of the system with respect to rider impacts.
For systems designed to be added to a standard barrier, the test results are valid only when the system is fitted to the model of barrier used in the tests since the performance will not necessarily be the same if the system is fitted to a different barrier.
