Resistance against wind load and load from passing vehicles A.1 General The objective of this annex is to provide assessment methods to demonstrate the capability of the product to withstand wind load and load from passing vehicles. The methods and criteria to assess the maximum load NRDs can withstand are provided within this annex. The methods for calculating the different loads that can act on NRDs are provided within Eurocode EN 1990 and Eurocode EN 1991. Requirements are set separately for acoustic and structural elements. In case acoustical and structural elements are not distinct, limits for structural elements apply. The temperature range, within limits of -40 °C to +70 °C, over which the requirements in A.3 to A.4 are met, shall be reported. NOTE In consideration of the various characteristics of the materials (inhomogeneity, creep, de-formations, ageing), an additional reduction of the bearing capacity may become necessary. A.2 Assessment of the performance A.2.1 Structural elements Structural elements are calculated according to the applicable Eurocodes. A.2.2 Acoustic elements A.2.2.1 General The acoustic elements shall be tested according to the following method. The load test shall be carried out on a representative sample which shall include an appropriate number of acoustic elements of the longest span for the element type, with posts or other supports similar to those used in practice. The supports shall be held in the horizontal plane and restrained from lateral movement and rotation. The supports may be propped if only the flexure of the acoustic elements is to be tested, otherwise the supports shall be fixed as in intended use. The test panel shall be allowed to reach equilibrium under laboratory conditions for at least 3 h before testing. Load tests shall be carried out at 20 °C. If the product is intended to be used at very low or very high temperatures, then the test may be repeated at -40 °C and/or +70 °C with appropriate conditioning time, if the material is regarded as being temperature sensitive. If the strength or stiffness of the load carrying material depends on temperature, the effect of temperature differing from range +10 to +30 shall be taken into consideration in testing if the intended temperature range is wider than presented above. Results shall show that temperature variation does not cause failure in the performance of joints (acoustic element detaches from posts in the lowest temperature of the specified range, connections (screw hole in the acoustic elements) allow for shrinkage and expansion in the whole range of temperatures specified by the manufacturer.
For NRD’s with asymmetrical design (geometry, characteristic of materials .), the results could be different on each side. In this case, the tests must be performed on the weakest side. In case of a family of products, the weakest product of the family has to be tested. SIST EN 1794-1:2018

The article discusses the EN 1794-1:2018 European Standard, which establishes criteria for categorizing road traffic noise reducing devices based on their mechanical performance. These criteria apply to all devices, regardless of the materials used, and take into account different conditions and optional requirements to accommodate the diversity of practices in Europe. The standard separates different aspects of performance into annexes, while safety considerations in case of damage to these devices are covered in EN 1794-2. The article emphasizes that this standard only assesses the current behavior of the products and suggests using EN 14389-2 to evaluate their long-term performance. Additionally, the article notes that the test procedure described in Annex A does not consider the fatigue effect.
