In addition to using this document, it is recommended that product Technical Committees contact CEN/TC 126 for advice on acoustic issues relating to the treatment of acoustics in technical specifications. CEN/TR 15226:20064 1 Scope This document specifies the technical requirements relating

12、 to acoustics for a product standard, European Technical Approval Guidelines (ETAG) or European Technical Approval (ETA) for a specific building product or equipment, or a family of building products or equipment. In particular, it gives advice on how to write requirements in response to the mandate

13、d characteristics on acoustics under the Construction Products Directive. NOTE 1 In the remainder of this document, the terms used relate to CEN and product standards. The concepts are, however, equally applicable to the European Organisation for Technical Approvals (EOTA). The purpose of this docum

14、ent is to assist the product Technical Committees in preparing acoustic clauses to ensure that such product standards: are as homogeneous as possible, with each individual product standard having the same basic structure; are in full accordance with the standards for the measurement of acoustic prop

15、erties; reflect the latest technical knowledge of methods of determining the acoustical properties from the specific family of building products or equipment under consideration. NOTE 2 Clause 2 lists the European and International Standards to be used in the drafting of acoustic provisions standard

16、. Annex A contains an outline of a typical acoustic product standard summarizing the information that is required. Annex B contains guidance on choosing appropriate properties. Annex C describes the relevant measured acoustic properties for common products. 2 Normative references The following refer
