L'évaluation des résultats d'un essai interlaboratoire européen réalisé en 1998 a montré que les exigences indiquées dans l'EN ISO 140-1 étaient insuffisantes pour les cloisons à doubles parements légers. L'annexe qui suit est par conséquent ajoutée.

L'évaluation des résultats d'un essai interlaboratoire européen réalisé en 1998 a montré que les exigences indiquées dans l'ISO 140-3 étaient insuffisantes pour les cloisons à doubles parements légers. L'annexe qui suit est par conséquent ajoutée.

Le présent document spécifie une méthode de laboratoire pour le mesurage de la transmission du bruit de choc par les planchers nus ou recouverts d'un revêtement, en utilisant une machine à chocs normalisée.

ISO 140-11:2005 specifies methods for measuring the acoustic properties of floor coverings from the viewpoint of reducing impact sound transmission. The purpose of ISO 140-11:2005 is to establish a method for determining the impact sound insulation of a floor covering under standard test conditions. The test is limited to the specification of procedures for the physical measurement of sound originating from an artificial impact source (tapping machine) under laboratory conditions and is not directly related to the subjective significance of the results. In ISO 140-11:2005, a test method is described using the standard tapping machine to simulate impact sources like human footsteps with shoes. In addition, methods using a modified tapping machine and a heavy/soft impact source are also introduced in informative Annexes C and E for the assessment of impact sound insulation of a floor covering against impact sources with strong components at low frequencies, such as human footsteps or children jumping. As a simplified method for the measurement of the reduction of floor impact sound pressure level by soft and resilient floor coverings, the method using a wooden mock-up floor is introduced in Annex D. ISO 140-11:2005 is applicable to all floor coverings, whether single or multi-layered, as installed on lightweight floors. In the case of multi-layered coverings, they can be factory-assembled or assembled at the test site. The test method is applicable only to laboratory measurements. It does not contain any provision that permits an assessment of the effectiveness of a floor covering in situ.

Le présent document spécifie une méthode de laboratoire pour le mesurage des propriétés d'isolation aux bruits aériens des dispositifs de doublage de paroi. La méthode s'applique à tous les ouvrages et produits utilisés en doublage de paroi horizontale ou verticale.

This document specifies a laboratory method for measuring the airborne sound insulation of building products, such as walls, floors, doors, windows, shutters, façade elements, façades, glazing, small technical elements, for instance transfer air devices, airing panels (ventilation panels), outdoor air intakes, electrical raceways, transit sealing systems and combinations, for example walls or floors with linings, suspended ceilings or floating floors. The test results can be used to compare the sound insulation properties of building elements, classify elements according to their sound insulation capabilities, help design building products which require certain acoustic properties and estimate the in situ performance in complete buildings. The measurements are performed in laboratory test facilities in which sound transmission via flanking paths is suppressed. The results of measurements made in accordance with this document are not applicable directly to the field situation without accounting for other factors affecting sound insulation, such as flanking transmission, boundary conditions and total loss factor.
