11、29052-1 : 1992 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 p
12、arameters that deter- mine the sound insulation of such floors in dwellings. of the standards indicated below. Members of IEC and IS0 maintain registers of currently valid International Standards.

13、easurements using single-point translation excitation with an attached vibra- tion exciter. 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
14、. It does not apply to loadings lower than 0,4 kPal), for example materials in wall linings, or greater than 4 kPal), for example materials under machinew foundations (see note 2). This part of IS0 9052 is mainly intended to be used for compar- ing production samples of similar materials of known sp
15、ecified quality. For restrictions concerning the airflow resistivity of the resilient material to be tested, see 8.2. NOTES 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 fibr
16、e. 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 %. 2 A further part of IS0 9052 will deal with the determination of dynamic stiffness of mater
17、ials used in technical floating floors (high static load). 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of IS0 9052. At the time of publication, the editions indicated were valid. All standards are subject
18、 to revision, and parties to agreements based on this part of IS0 9052 are encouraged to investigate the possibility of applying the most recent editions IS0 9053 : -21, Acoustics - Materials for acoustical appli- cations - Determination of aidlow resistance. 3 Definitions 3.1 dynamic stiffness: The
