Modification of VRS tested in accordance with EN 1317-1, ####EN 1317-2$$$$, EN 1317-3 or ENV 1317-4 A.1 General This annex gives rules for evaluation of conformity concerning Parts 1, 2, 3, 4 of an approved VRS, which has been modified and methods by which to demonstrate the extent to which the modification has changed its performance. NOTE After Initial Type Testing, VRS may be altered on the basis of new technology and knowledge whereby improvements and modification of their components can take place. In some cases, as specified in A.4 and A.5, a VRS may be evaluated by a reduced number of impact tests or by calculations, computer simulations or simple loading tests. A.2 Modified VRS A modified VRS is a VRS that previously conformed to this document, which has been changed by material design or dimension in such a way that can affect characteristics, which are subject to requirements in this document. NOTE 6.2.1.5 of this part provides requirements for evaluating the effect of modifications. A.3 Types of modifications The types of modifications shall be classified in accordance with Table A.1. Table A.1 – Categories of modifications Category Change Description A Slight Modifications requiring no mechanical changes to the VRS. B Moderate Modifications to one or more components where their effects on the performance of the VRS can be determined by static or dynamic analysis or other appropriate means. C Significant Modifications in excess of A or B.
A.5 Reduced test matrix for category C A.5.1 General Where a change requires additional impact tests, the number of tests may be reduced in comparison to the original matrix of EN #EN 1317-2$, EN 1317-3 or ENV 1317-4, in the following cases. A.5.2 Longitudinal barrier or transition The barrier shall be deemed to conform to the requirements of this document without the need to carry out the TB 11 test, provided that modified barrier has passed the TB 32 or higher level test, in accordance with the ITT, and provided that all the following conditions are satisfied: There are no changes made to the external geometry (traffic face), especially the location of the main components and their dimensions, which could modify the interaction with other components or with the light vehicle. In the case of a barrier with only one longitudinal rail, the normalized dynamic deflection2 from the containment level test on the modified product shall not differ by more than +20 % to -10 % from the normalized dynamic deflection determined under the same performance level and conditions in the original ITT. In the case of barriers with more than one rail, the modification shall not affect the rails in contact with the car during the TB11 test and the normalized dynamic deflection2 from the containment level test on the modified product shall not differ by more than +20 % to -10 % from the normalized dynamic deflection determined under the same performance level and conditions in the original ITT. In the case where some of the modified components are subject to controlled failure, it shall be demonstrated that the behaviour with small vehicle is not affected.

####Resistance to snow removal C.1 General Snow removal may damage a safety barrier which has not a sufficient resistance to snow removal.
C.2 Scope This normative annex includes a classification of safety barriers for the resistance to snow removal. It includes the horizontal and vertical pressure of ploughed snow against the rail and minor impacts caused by the plough in the traffic face and upper edge of the rail. A simplified evaluation method is intended for normal steel beam barriers, rope fences and monolithic pre-cast or cast-in-place concrete barriers. A test is possible for other barrier types.
The specifying authority shall decide if classification is required.
This annex is not intended to be used with crash cushions, terminals and transitions. C.3 Requirements Metal beam safety barriers shall be classified into classes on the basis of Table C.1. Table C.1 - Resistance to snow removal of metal beam safety barriers
