This document describes the basic requirements for the verification of ultimate and serviceability limit states and the resistance to fatigue either of the noise barrier or its components by means of analytical methods and/or tests. Analytical methods can be used for the determination of the characteristic values and design values. Where sufficient information is not available, the analytical procedure may be combined with results from tests. The following types of test procedures may be used: - Test on small samples for defining detail categories, which may not be covered by Eurocodes (verification procedure A provided within the present European standard); - Test on a global element for defining the limit state against fatigue (verification procedure B provided within the present European standard). In order to verify the assumptions of the design model, a static load test of the components shall be performed according to EN 16727-1. - Alternatively, fatigue resistance of the noise barrier components can be determined for defined loading conditions by mean of full scale tests under a given representative loading (verification procedure C provided within the present standard).
