EN 12758:2002 (E) 4 1 Scope This European Standard assigns sound insulation values to all transparent, translucent and opaque glass products, described in European Standar
18、ds on 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, acco
19、rding 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 wi
20、th confidence by non-specialists. By adopting the principles of this standard, the formulation of acoustic requirements in Building Codes, and of product specification to satisfy particular needs for glazing is simplified. It is recognised that the acoustic test procedures of EN ISO 140-1 and EN ISO
21、 140-3 relate fully 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. Guidelines on how to adapt these to include glass
22、blocks, bricks, structural glazing, channel-shaped glass and pavers are offered in clause 4. NOTEPerformance variation in windows. All the considerations of this standard relate to glass alone. Incorporation of them into windows may cause changes in acoustic performance, owing to other influences, i
23、ncluding frame design, frame material, mounting method, air tightness, etc. Measurements of the sound insulation of complete windows (glass and frame) may be undertaken to resolve such issues.

35、. 3 Terms and definitions For the purposes of this European Standard the following terms and definitions apply. 3.1 glass products broad definition of product types can be only indicative, in recognition of future research, innovation and development of new materials and glazing techniques 3.2 singl
36、e glass glass is referred to as single glass when the product is a single leaf of homogeneous or monolithic glass and includes annealed, toughened (by heat or chemical treatment) and coated glasses. Their body colour may vary, according to the presence of small additives at the production stage. See
37、 references EN 572-1, EN 572-2, EN 572- 4, EN 572-5, EN 1748-1, EN 1748-2, EN 1863-1, EN 12150-1, EN 12337-1, prEN 13024-1, EN 1096-1 3.3 wired glass EN 572-3 and EN 572-6 define the essential characteristics of wired glass. The presence of wire is found not to modify the basic acoustic performance
38、from that associated with homogeneous glass of the same overall thickness. For the purposes of this standard, wired glass is, therefore, included in the definition of “single glass“ 3.4 laminated glass when leaves of homogeneous glass are permanently bonded together by the sandwiching of interlayers
39、, the resultant product is referred to as laminated glass, and is defined in EN ISO 12543-1. The most common lamination material is polyvinyl butyral (p.v.b.). When referring to laminated glasses, the interlayer type and makeup shall be specified, owing to probable differentiation of acoustic perfor
40、mance 3.5 insulating glass units hermetically sealed units, having two or more glasses in their construction, separated by cavities, which usually contain dry air, but which may contain other gases for special purposes. They are referred to as insulating glass units (I.G.U.). Document prEN 1279-1 co
41、vers these variants. The individual glass components may comprise products from the categories of 3.2, 3.3 and 3.4 3.6 multiple glazing when two glasses are separated by unsealed cavities, they are referred to as coupled windows or double windows or, if held in proprietary framing, as secondary sash
42、es. Generally the performance of those products should be tested EN 12758:2002 (E) 7 3.7 glass blocks and pavers glass blocks and pavers are the subject of prEN 1051-1 and prEN 1051-2. Walls of glass blocks are covered by prEN 12725. Mostly, they are formed by fusing two halves together, so that the
43、y are fully sealed, though not with dry air. They are available in a wide range of sizes, quite often though of size 300 mm x 300 mm x 100 mm, and the glass thickness is of the order of 12 mm, which may be transparent, translucent and/or coloured, usually for decorative purposes. Because opposite fa
44、ces of these products comprise thick glass, with significant separation, their associated sound insulation may be of importance. Pavers are products (most often rectangular or circular) which are primarily designed to be load-bearing to pedestrian or vehicular traffic. Their essential feature of int
45、erest to acoustic design is that they are fabricated from thick, solid glass 3.8 structural sealant glazing and structural assemblies as an alternative to glass being held in position by framing, assemblies have been devised which may include bolts and/or adhesive fixing (with or without supporting
46、structures) and are referred to as structural glazing assemblies. Acoustically, such assemblies may behave differently from their framed equivalents, and laboratory measurements of performance are strongly recommended, for which care must be taken to ensure that a representative sample of bolts, joi
47、nts, etc., is included in the test sample 3.9 channel-shaped glass document EN 572-7 covers these. Typically, these are about 3 m long and 300 mm wide, and shaped into a U-section, whose smaller arms are of the order of 50 mm long. Walls may be built of these components by joining them together, as
48、a single or double skin, using a suitable flexible sealant. When the acoustic performance of such structures is required, testing of a representative sample of the particular configuration should be undertaken 4 Test methods Acoustic performance data shall be obtained under the conditions specified
49、by EN ISO 140-1, EN ISO 140-3 and EN ISO 717-1. For laminated glasses, owing to temperature dependency, the specimen temperature shall be between 17 C and 23 C. NOTE 1For best reproducibility it is recommended that the test opening for glass panes, as described in annex C of EN ISO 140-1:1997, be adopted. Some variation in panel size etc., to those in EN ISO 140-1, may be necessary for glass blocks, pavers, structural assemblies and channel-shaped glass, in order to include a
