This European Standard shall be given the status of

15、a national standard, either by publication of an identical text or by endorsement, at the latest by March 2016 and conflicting national standards shall be withdrawn at the latest by June 2017. Attention is drawn to the possibility that some of the elements of this document may be the subject of pate

16、nt rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 14388:2005. The main changes compared to the previous edition are: Two standards EN 1793-2 and EN 1793-6 are now specified for the measurement of airborne sound insu

17、lation, each with a specific field of application. Revision of Annex ZA according to Regulation EU 305/2011. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of the EU Construction Pro

18、ducts Regulation. For relationship with the EU Construction Products Regulation, see informative Annex ZA, which is an integral part of this document. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this Europe

BS EN 14388:2015EN 14388:2015 (E) 4 1 Scope This European Standard specifies requirements for the following road traffic noise reducing devices (as defined in 3.1): noise barriers (as defined in 3.2); claddings (as defined in 3.5); road

21、 covers (as defined in 3.6); and added devices (as defined in 3.7). These devices may include both acoustic and structural elements, where: an acoustic element is an element whose primary function is to provide a noise reducing device with sound insulation, diffraction and/or sound absorption, it is

22、 a part of noise reducing device to be used along roads, and a structural element is an element whose primary function is to support or hold in place acoustic elements, it is a part of noise reducing device to be used along roads. Depending upon the design of the noise reducing device, structural el

23、ements may potentially be tested separately from acoustic elements. They may be made of different materials for which specific standards are to be applied in accordance with the specifications prescribed hereafter. Some of the materials may contain dangerous substances, the reason why all the materi

24、als are declared. This European Standard identifies the relevant characteristics of road traffic noise reducing devices, the corresponding methods of evaluation and specifies the provisions on evaluation of conformity and marking. This European Standard covers acoustic, non-acoustic and long term pe

25、rformance, but not aspects such as resistance to vandalism or requirements of visual appearance. This European Standard does not cover road surfaces or the airborne sound insulation of houses. 2 Normative references The following documents, in whole or in part, are normatively referenced in this doc
