This document deals with determination and assessment of sound insulation performances of all transparent@ translucent and opaque glass products@ described in the document for basic@ special basic or processed glass products@ when intended 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 refers to laboratory measurement method described in EN ISO 10140-1:2016@ Annex D and defines extension rules that can be applied without further testing. It also provides typical performance data for a range of common glass products that can be used in the absence of measured data. All the considerations of this document 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@ glazing 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.
