22、 7 Bibliography . 8 EN ISO 10848-3:2006iv 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
23、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 Electr
24、otechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted
25、 by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
26、rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 10848-3 was prepared by the European Committee for Standardization (CEN) Technical Committee CEN/TC 126, Acoustic properties of building elements and of buildings, in collaboration with Technical Committee I
27、SO/TC 43, Acoustics, Subcommittee SC 2, Building acoustics, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement). ISO 10848 consists of the following parts, under the general title Acoustics Laboratory measurement of the flanking transmission of airborne a
28、nd impact sound between adjoining rooms: Part 1: Frame document Part 2: Application to light elements when the junction has a small influence Part 3: Application to light elements when the junction has a substantial influence The following part is under preparation: Part 4: Application to all other
29、cases EN ISO 10848-3:20061Acoustics Laboratory measurement of the flanking transmission of airborne and impact sound between adjoining rooms Part 3: Application to light elements when the junction has a substantial influence 1 Scope ISO 10848 specifies measurement methods to be performed in a labora
30、tory test facility in order to characterize the flanking transmission of one or several building components. The measured quantities can be used to compare different products, or to express a requirement, or as input data for prediction methods, such as EN 12354-1 and EN 12354-2. This part of ISO 10
31、848 is specifically referred to in ISO 10848-1:2006, 4.4, as being a supporting part to the frame document. This part of ISO 10848 applies to structurally connected light elements forming a T or X junction. A light element is defined in ISO 10848-1:2006, Clause 3. The relevant quantity to be measure
32、d is selected according to ISO 10848-1:2006, 4.4. The performance of the building components is expressed either as an overall quantity for the combination of elements and junction (such as Dn,fand/or Ln,f) or as the vibration reduction index Kijof a junction. Dn,fand Ln,fdepend on the actual dimens
33、ions of the elements, while Kijis in principle an invariant quantity. For general application of the test results, Dn,fand Ln,fare the relevant quantities to measure for lightweight, well-damped types of elements (for example, timber or metal framed stud walls or wooden floors on beams), where the a
34、ctual situation has no real influence on the sound reduction index and damping of the elements. If the acoustical properties of the elements are substantially influenced by the actual situation, Kijis the relevant quantity to measure. 2 Normative references The following referenced documents are ind

39、 terms and definitions apply. 3.1 normalized flanking level difference Dn,fdifference in the space and time average sound pressure level produced in two rooms by one or more sound sources in one of them, when the transmission only occurs through a specified flanking path NOTE Dn,f is normalized to a
40、n equivalent sound absorption area (A0) in the receiving room and expressed, in decibels: n,f 1 2010 lg dBADLLA= (1) where L1is the average sound pressure level in the source room, in decibels; L2is the average sound pressure level in the receiving room, in decibels; A is the equivalent sound absorp
41、tion area in the receiving room, in square metres; A0is the reference equivalent sound absorption area, in square metres; A0= 10 m2. ISO 10848-1:2006 3.2 normalized flanking impact sound pressure level Ln,fspace and time average sound pressure level in the receiving room produced by a standard tappi
42、ng machine operating at different positions on a tested floor in the source room, when the transmission only occurs through a specified flanking path NOTE Ln,fis normalized to an equivalent sound absorption area (A0) in the receiving room and is expressed in decibels: n,f 2010 lg dBALLA=+ (2) where
43、L2is the average sound pressure level in the receiving room, in decibels; A is the equivalent sound absorption area in the receiving room, in square metres; A0is the reference equivalent sound absorption area, in square metres; A0= 10 m2. ISO 10848-1:2006 EN ISO 10848-3:200633.3 vibration reduction
44、index Kijvalue given by the following equation and expressed in decibels: ,10 lg dBijij v ijijlKDaa=+ (3) where ,vijD is the direction-averaged velocity level difference between elements i and j, in decibels; lijis the junction length between elements i and j, in metres; ai, ajare the equivalent abs
45、orption lengths of elements i and j, in metres. NOTE 1 The equivalent absorption length depends on the structural reverberation time as defined in ISO 10848-1:2006, 3.8. For lightweight, well-damped types of elements where the actual situation has no real influence on the sound reduction index and d
46、amping of an element, ajis taken as numerically equal to the surface area Sjof the element, aj= Sj/l0, where the reference length l0= 1 m. NOTE 2 The vibration reduction index is related to the vibrational power transmission over a junction between structural elements, normalized in order to make it
47、 an invariant quantity. 4 Measuring equipment The equipment shall fulfil the requirements given in ISO 10848-1:2006, Clause 5. 5 Test arrangement 5.1 Requirements for the laboratory The general requirements for test specimens and test rooms given in ISO 10848-1:2006, Clause 6 shall be fulfilled. For
48、 measurements of the vibration reduction index Kijwith structure-borne excitation, it is not necessary to have an envelope forming a source and receiving room around the junction. A test object with a vertical junction line may be placed directly onto a heavy concrete floor fulfilling the condition
49、expressed in ISO 10848-1:2006, 8.2. The situation is a little more complicated for horizontal junctions, since stability shall be provided. In most situations, it is necessary to use the same type of test facility for all types of measurement, with the exception that the requirements for the airborne sound insulation between the volumes do not apply for measurements of Kijwith structure-borne excitation. 5.2 Installation of the test junction Because the behaviour of light elements is not influenced significantly
