Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types of ISO document should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives ).

ISO draws attention to the possibility that the implementation of this document may involve the use of (a) patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a) patent(s) which may be required to implement this document. However, implementers are cautioned that this may not represent the latest information, which may be obtained from the patent database available at www.iso.org/patents . ISO shall not be held responsible for identifying any or all such patent rights.

Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement.

This document was prepared by Technical Committee ISO/TC 160, Glass in building.

This second edition cancels and replaces the first edition (ISO 22897:2003), which has been technically revised.

The main changes are as follows:

• the calibration procedure has been removed and reference is now made to ISO 10140-1:2021, Annex D;
• the extension rules have been expanded;
• Table 1 with typical performance data has been extended;
• Annex A on the characterization of polyvinyl butyral interlayers has been added.

1 Scope

This document establishes a method to determine and assess sound insulation performances of all transparent, translucent and opaque glass products, 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 or supplementary characteristic.

This document refers to laboratory measurement method described in ISO 10140-1:2021, 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 or glass products alone. Incorporation of them into windows can cause changes in acoustic performance as a result of other influences, e.g. frame design, frame material, glazing material or method, mounting method, air tightness. Measurements of the sound insulation of complete windows (glass and frame) can be undertaken to resolve such issues.
