适用范围：This European Standard assigns sound insulation values to all transparent, translucent and opaque glassproducts, described in the European Standards for basic, special basic or processed glass products, whenintended to be used in glazed assemblies 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 acousticperformance which enables assessment of compliance with the acoustic requirements of buildings.Rigorous technical analysis of measurement data remains an option, but this standard is intended to enablethe derivation of simpler indices of performance, which can be adopted with confidence by non-specialists.By adopting the principles of this standard the formulation of acoustic requirements in Building Codes and forproduct 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 panesand their combinations. Although the same principles should be followed as closely as possible, it is inevitablethat some compromises are necessary, because of the bulkier construction of other glazing types, e.g. glassblocks, paver units, channel-shaped glass, structural glazing and structural sealant glazing. Guidelines on howto adapt the test 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 intowindows may cause changes in acoustic performance as a result of other influences, e.g. frame design, framematerial, glazing material/method, mounting method, air tightness, etc. Measurements of the sound insulationof complete windows (glass and frame) may be undertaken to resolve such issues.
