This document specifies the method for declaring the technical classification relating to acoustics for a Product Standard including DoP, or European assessment document (EAD) including 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 technical specifications in response to the mandated characteristics on acoustics under the Construction Products Regulation.
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 document is to assist the 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 and declaration of acoustic properties;
-
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 Annex A lists the European and International Standards to be used in the drafting of acoustic provisions standards. Annex B contains guidance on choosing appropriate properties. Annex C describes the relevant measured acoustic properties for common products.
