EN ISO 10848, of which this is part 2, describes measurement methods to be performed in a laboratory test facility in order to characterise 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 3 is specifically referred to from clause 4.3 of EN ISO 10848-1, as being a supporting standard to the frame document. This part applies to structurally connected light elements forming a T or X junction. Clause 8.2 of EN ISO 10848-1 makes it necessary for a light test element to have a surface mass which is less than or equal to 0,16 times the surface mass of the thinnest element of the test facility rigidly connected to this element. The relevant quantity to be measured is selected according to clause 4.3 of Part 1 of the standard. The performance of the building components are expressed either as an overall quantity for the combination of elements and junction like Dn,f and/or Ln,f or as the vibration reduction index Kij of a junction. Dn,f and Ln,f depend on the actual dimensions of the elements, while Kij is in principle an invariant quantity. For general application of the test results, Dn,f and Ln,f are 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 actual 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, Kij is the relevant quantity to measure.
