Acoustique - Détermination de la raideur dynamique - Partie 1: Matériaux utilisés sous les dalles flottantes dans les bâtiments d'habitation

La présente partie de l'ISO 9052 spécifie la méthode d'essai permettant de déterminer la raideur dynamique des matériaux résilients utilisés sous les dalles flottantes. La raideur dynamique est l'un des paramètres qui déterminent l'isolation acoustique de ces dalles dans les bâtiments d'habitation. La présente partie de l'ISO 9052 s'applique à la détermination de la raideur dynamique par unité de surface de matériaux résilients à surfaces lisses (voir chapitre 6), utilisés en couche continue sous les dalles flottantes, dans les lieux d'habitation. Elle ne s'applique pas à des charges inférieures à 0,4 kPa1), par exemple à des matériaux de revêtements muraux, ou supérieures à 4 kPa1), par exemple à des matériaux situés sous des fondations supportant des machines (voir note 2). Cette partie de l'ISO 9052 est principalement destinée à être utilisée lors de la comparaison d'échantillons de fabrication avec des matériaux similaires de qualité spécifiée conn

IS0 9052-l : 1989 (E) Foreword IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 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, govern- mental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the IS0 Council. They are approved in accordance with IS0 procedures requiring at least 75 % approval by the member bodies voting. International Standard IS0 9052-l was prepared by Technical Committee ISO/TC 43, Acoustics. IS0 9052 will consist of the following parts, under the general title Acoustics - Deter- mina tion of dynamic stiffness : - Part 7: Materials used under floating floors in dwellings 0 - Part buildings 2: Materials used for vibration and sound insulation of equipment in International Organization for Standardization, 1989 Printed in Switzerland SIST EN 29052-1:1997



INTERNATIONAL STANDARD IS0 9052-l : 1989 (E) Acoustics - Determination of dynamic stiffness - Part 1: Materials used under floating floors in dwellings 1 Scope This part of IS0 9052 specifies the test method for determining the dynamic stiffness of resilient materials used under floating floors. Dynamic stiffness is one of the parameters that deter- mine the sound insulation of such floors in dwellings. This part of IS0 9052 applies to the determination of dynamic stiffness per unit area of resilient materials with smooth sur- faces (see clause 6) used in a continuous layer under floating floors in dwellings. It does not apply to loadings lower than 0,4 kPal), for example materials in wall linings, or greater than 4 kPa’), for example materials under machinery foundations (see note 2). of the standards indicated below. Members of IEC and IS0 maintain registers of currently valid International Standards. IS0 7626-2 : - 2), Vibration and shock - Experimental deter- mination of mechanical mobility - Part2: Measurements using single-point translation excitation with an attached vibra- tion exciter. IS0 9053 : - 2), Acoustics - Materials for acoustical appli- cations - Determination of aHlow resistance. 3 Definitions This part of IS0 9052 is mainly intended to be used for compar- ing production samples of similar materials of known specified quality. For restrictions concerning the airflow resistivity of the resilient material to be tested, see 8.2. 3.1 dynamic stiffness: The ratio of dynamic force to dynamic displacement. For the purposes of this part of IS0 9052, dynamic stiffness per unit area, s’, is used and is given by the following equation: FIS s’ = - . . . (1) NOTES Ad 1 The dependence of dynamic stiffness on prestatic load is of minor importance in the case of materials usually applied in wall linings, for example polystyrene or mineral fibre. The differences between dynamic stiffness values measured with a static load of 2 kPa in ac- cordance with this part of IS0 9052 and those measured with a very low preload are of the order of 10 % to 20 %. where S is the area of the test specimen; F is the dynamic force acting perpendicularly on the test specimen ; 2 A further part of IS0 9052 will deal with the determination of dynamic stiffness of materials used in technical floating floors (high static load). Ad is the resulting dynamic change in thickness of the resilient material. In this part of IS0 9052, the following quantities are used: 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of IS0 9052.

IS0 9052-l : 1989 (E) 3.2 natural frequency,&: Frequency of free oscillation of a system. For the test set-up shown in figure 1, the inertia of the base shall be such that in vibration its velocity is negligible compared with that of the load plate. The natural frequency of a resiliently supported floor is given by the following equation : For the test arrangements shown in figures 2 and 3, the mass of the baseplate shall be at least 100 kg. 6 Test specimen where At least three square specimens of dimensions 200 mm x 200 mm shall be taken. The surfaces of the test specimens shall be considered to be smooth if the surface irregularities are less than 3 mm. s’ is the dynamic resilient material ; stiffness per unit area of the installed m’ is the mass per unit area of the supported floor. The test specimen shall be covered with a waterproof plastic foil, approximately 0,02 mm thick, on which a thin paste of plaster of Paris and water is applied to a depth of at least 5 mm so that any unevenness is covered. Before the plaster begins to set, the load plate shall be bedded onto it as shown in figur
