CEN/TC 229/WG 2 - Products for which the stability requirements is in conjunction with other dominant requirements

This European Standard specifies criteria and material-specific requirements of precast concrete noise barriers and acoustic elements to be used in the construction and rehabilitation of new and existing traffic roads.
Furthermore, this European Standard describes test methods and defines quality control, type and scope of factory production control and certification of conformity, which can also be used for other Transport systems. In this case additional requirements could be necessary.
This European Standard does not apply to load bearing components, such as posts or other supporting members, whose principal function is to support noise barriers and acoustic elements. It also does not apply to the acoustic properties of noise barriers and acoustic elements.

Reinforced concrete elements of special shapes for highway equipment. Product characteristics are related to impact resistance, compressive strength, bending tensile strength.

This standard covers prefabricated concrete elements which can be used together or in combination with other elements to erect fences. The current concrete elements include posts (reinforced, prestressed or post-tensioned concrete), solid or base or open panels, slabs, rails, spurs, struts and gravel boards. The purpose of this standard is to define: a) the terminology; b) the main guidelines needed for concrete elements which are well suited to their intended use.

This European Standard specifies the requirements for reinforced and prestressed precast concrete floor slats used in slatted floors for the housing of livestock and provides for the evaluation of conformity of these products. This standard does not cover slats for loadings other than stock and stockmen.
