Glass in building - Glazing and airborne sound insulation - Product descriptions, determination of properties and extension rules

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 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 acoustic performance 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 enable the 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 for product specification to satisfy particular needs for glazing is simplified.
It is recognised that the acoustic test procedures contained within EN ISO 140-1 and EN ISO 140-3 relate only to glass panes and their combinations. Although the same principles 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 test procedures for these glazing types are offered in Clause 4.
All the considerations of this standard relate to panes of glass/glazing 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.

Glas im Bauwesen - Glas und Luftschalldämmung - Produktbeschreibungen, Bestimmung der Eigenschaften und Erweiterungsregeln

Dieses Dokument befasst sich mit der Festlegung und Beurteilung von Schalldämmwerten für alle durchsichtigen, durchscheinenden und opaken Glaserzeugnisse, die in den Europäischen Normen über Basisglaserzeugnisse, spezielle Basisglaserzeugnisse oder über weiterverarbeitete Glaserzeugnisse mit Schallschutzeigenschaften, vorgesehen für den Gebrauch in verglasten Bauteilen von Gebäuden, beschrieben sind und die entweder als Hauptzweck oder als ergänzende Charakteristik Schalldämmung aufweisen.
Dieses Dokument bezieht sich auf Labormessverfahren, die in EN ISO 10140 1:2016, Anhang D beschrieben werden, und legt erweiterte Regeln fest, die ohne weitere Prüfungen angewandt werden können. Es liefert außerdem typische Schalldämmwerte für einen großen Bereich gängiger Glaserzeugnisse, die verwendet werden können, wenn keine Messwerte zur Verfügung stehen.
Alle Überlegungen dieses Dokuments beziehen sich nur auf Scheiben aus Glas/Glaserzeugnisse. Ihr Einbau in Fenster kann Änderungen der akustischen Eigenschaften verursachen, die auf andere Einflüsse zurückzuführen sind; hierzu gehören die Konstruktion der Rahmen, der Rahmenwerkstoff, das Verglasungsmaterial/ verfahren, die Einbaumethode, Luftdichtigkeit usw. Zur Klärung dieser Frage dürfen Messungen der Schalldämmung an vollständigen Fenstern (Scheiben und Rahmen) durchgeführt werden.

Verre dans la construction - Vitrages et isolation aux bruits aériens - Descriptions de produits, détermination des propriétés et règles d’extension

Le présent document traite de la détermination et de l’évaluation des performances d’isolation acoustique de tous les produits verriers transparents, translucides et opaques décrits dans le document relatif aux produits de base, aux produits de base spéciaux ou aux produits en verre traité, lorsqu’ils sont destinés à être utilisés dans des ensembles vitrés dans des bâtiments, et qui présentent des propriétés de protection acoustique, que ce soit en première intention ou comme caractéristique supplémentaire.
Le présent document se réfère à la méthode de mesurage en laboratoire décrite dans l’EN ISO 10140 1:2016, Annexe D, et définit des règles d’extension pouvant être appliquées sans essais supplémentaires. Il indique également les données de performance type pour une gamme de produits verriers courants, qui peuvent être utilisées en l’absence de données mesurées.
Toutes les considérations du présent document font référence aux verres et produits verriers seuls. Leur incorporation dans des fenêtres peut modifier la performance acoustique en raison d’autres influences, par exemple la conception du châssis, le matériau du châssis, le matériau/la méthode de vitrage, la méthode de montage, l’étanchéité à l’air, etc. Des mesures de l’isolation acoustique de fenêtres complètes (verre et châssis) peuvent être entreprises pour résoudre ces questions.

Steklo v gradbeništvu - Steklo in izolirnost pred zvokom v zraku - Opis proizvoda, opredelitev lastnosti in pravila razširitve

Ta evropski standard dodeljuje vrednosti izolirnosti pred zvokom vsem proizvodom iz prozornega, prosojnega in neprozornega stekla, ki so opisani v evropskih standardih za proizvode iz osnovnega, posebnega osnovnega ali obdelanega stekla in kadar so namenjeni uporabi v zastekljenih sestavih na stavbah, pri tem pa izkazujejo lastnosti zaščite pred hrupom kot glavni namen ali pa dodatno lastnost.
Ta dokument določa postopek, s katerim je mogoče proizvode iz stekla oceniti glede na njihove akustične lastnosti, kar omogoča oceno skladnosti z akustičnimi zahtevami stavb.
Možna je tudi stroga tehnična analiza merilnih podatkov, vendar pa je ta standard namenjen omogočanju izpeljave enostavnejših indeksov zmogljivosti, ki jih lahko brez pomislekov sprejmejo nestrokovnjaki.
S sprejetjem načel tega standarda se poenostavi formulacija akustičnih zahtev v gradbenih predpisih in za specifikacije proizvodov, da se izpolnijo določene potrebe glede zasteklitve.
Znano je, da se postopki akustičnega preskusa iz standardov EN ISO 140-1 in EN ISO 140-3 navezujejo samo na steklene plošče in njihove kombinacije. Čeprav naj bi se enaka načela čim bolj upoštevala, se kompromisom ni mogoče izogniti zaradi zajetne konstrukcije drugih vrst zasteklitve, npr. steklenih blokov, tlakovnih enot, stekla v obliki kanala, strukturne zasteklitve in strukturne tesnjene zasteklitve. Smernice glede sprejetja preskusnih postopkov za te vrste zasteklitve so na voljo v točki 4.
Vsi vidiki tega standarda se navezujejo na plošče iz stekla/samo zasteklitev. Vgradnja v okna lahko spremeni akustične lastnosti zaradi drugih vplivov, npr. zasnove okvirja, materiala okvirja, materiala/metode zasteklitve, metode pritrditve, zračne neprepustnosti itd. Takšne težave je mogoče odpraviti z merjenjem izolirnosti pred zvokom pri celotnih oknih (steklo in okvir).

1 Scope

This document deals with determination and assessment of sound insulation performances of 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 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.
