Foreword
This Technical Report (CEN/TR 15226:2006) has been prepared by Technical Committee CEN/TC 126
“Acoustic properties of building products and of buildings”, the secretariat of which is held by AFNOR.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.
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.
1 Scope
This document specifies the technical requirements relating 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 mandated 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 document 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 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 Clause 2 lists the European and International Standards to be used in the drafting of acoustic provisions
standard. 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.
