Introduction

ISO 10140 (all parts) concerns laboratory measurement of the sound insulation of building elements(see Table 1).

ISO 10140-1 specifies the application rules for specific elements and products including specificrequirements for the preparation and mounting of the test elements and for the operating and test conditions. This document and ISO 10140-3 contain the general procedures for airborne and impactsound insulation measurements respectively and refer to ISO 10140-4 and ISO 10140-5 where appropriate. For elements and products withouta specific application rule described in ISO 10140-1 it ispossible to apply this document and ISO 10140-3. ISO 10140-4 contains basic measurement techniquesISO 10140 (all parts) see Table .1 and processes. ISO 10140-5 contains requirements for test facilities and equipment. For the structure of

ISO 10140 (all parts) was developed to improve the layout for laboratory measurements ensurein laboratory and field measurements. ISO 10140 (all parts) aims at presenting a well-written and arranged format for laboratory measurements.

ISO 10140-1 is planned to be updated with application rules for other products.
