BS EN 12758:2011EN 12758:2011 (E) 4 1 Scope This European Standard assigns sound insulation values to all transparent, translucent and opaque glass products, described in the European Standards for basic, special basic or processed glass products, when intended to be used in glazed a
20、ssemblies in buildings, and which exhibit properties of acoustic protection, either as a prime intention or as a supplementary characteristic. This document outlines the procedure, by which glass products may be rated, according to their acoustic performance which enables assessment of compliance wi
21、th the acoustic requirements of buildings. Rigorous technical analysis of measurement data remains an option, but this standard is intended to enable the derivation of simpler indices of performance, which can be adopted with confidence by non-specialists. By adopting the principles of this standard
22、 the formulation of acoustic requirements in Building Codes and for product specification to satisfy particular needs for glazing is simplified. It is recognised that the acoustic test procedures contained within EN ISO 10140 relate only to glass panes and their combinations. Although the same princ
23、iples should be followed as closely as possible, it is inevitable that some compromises are necessary, because of the bulkier construction of other glazing types, e.g. glass blocks, paver units, channel-shaped glass, structural glazing and structural sealant glazing. Guidelines on how to adapt the t
24、est procedures for these glass products are offered in Clause 4. All the considerations of this standard relate to panes of glass/glass products alone. Incorporation of them into windows may cause changes in acoustic performance as a result of other influences, e.g. frame design, frame material, gla
25、zing material/method, mounting method, air tightness, etc. Measurements of the sound insulation of complete windows (glass and frame) may be undertaken to resolve such issues. 2 Normative references The following referenced documents are indispensable for the application of this document.

40、ng are examples of such assemblies: 1) Glass block walls; 2) Paver unit panels; 3) Channel shaped glass panels, single or dual glazed; 4) Structural sealant glazing; 5) Structural assemblies. NOTE 2 The dimensions of glass blocks, paver units and channel shaped glass do not allow them to be subjecte
