This document specifies measurement methods to characterize in the laboratory the acoustic radiation of a building element when it is directly excited by an airborne or structure-borne source. It is applicable to single-leaf and double-leaf elements (see ISO 12354-1:2017 Annex F, F2). The measured quantity can be used as input data for prediction methods, such as ISO 12354-1 and ISO 12354-2, to compare products, or to express a requirement.

ISO 10848 (all parts) specifies measurement methods to characterize the flanking transmission of one or several building components.
ISO 10848-4:2017 specifies laboratory and field measurements of buildings where at least one of the elements that form the construction under test is a Type A element (defined in ISO 10848‑1).
Laboratory measurements are used to quantify the performance of the junction with suppressed flanking transmission from the laboratory structure. Field measurements are used to characterize the in situ performance and it is not usually possible to suppress unwanted flanking transmission sufficiently; hence, the results are primarily representative of the performance of that junction when installed in that particular building structure.
The measured quantities can be used to compare different products, or to express a requirement, or as input data for prediction methods, such as ISO 12354‑1 and ISO 12354‑2.

ISO 10848 (all parts) specifies measurement methods to characterize the flanking transmission of one or several building components.
ISO 10848-3:2017 specifies laboratory and field measurements of buildings for Type B elements (defined in ISO 10848‑1) when the junction has a substantial influence.
Laboratory measurements are used to quantify the performance of the junction with suppressed flanking transmission from the laboratory structure. Field measurements are used to characterize the in situ performance and it is not usually possible to suppress unwanted flanking transmission sufficiently; hence, the results can only be considered representative of the performance of that junction when installed in that particular building structure.
ISO 10848-3:2017 is referred to in ISO 10848‑1:2017, 4.5 as being a supporting part to the frame document and applies to Type B elements that are structurally connected as defined in ISO 10848‑1.
The measured quantities can be used to compare different products, or to express a requirement, or as input data for prediction methods, such as ISO 12354‑1 and ISO 12354‑2.
The relevant quantity to be measured is selected according to ISO 10848‑1:2017, 4.5. The performance of the building components is expressed either as an overall quantity for the combination of elements and junction (such as Dn,f,ij and/or Ln,f,ij and/or Lne0,f,ij) or as the normalized direction-average velocity level difference  of a junction. Dn,f,ij, Ln,f,ij, Lne0,f,ij and  depend on the actual dimensions of the elements.

ISO 10848 (all parts) specifies measurement methods to characterize the flanking transmission of one or several building components. This document considers only laboratory measurements.
The measured quantities can be used to compare different products, or to express a requirement, or as input data for prediction methods, such as ISO 12354‑1 and ISO 12354‑2. However, the measured quantities Dn,f, Ln,f and Lne0,f only represent the performance with the dimensions for the test specimens described in this document.
ISO 10848-2:2017 is referred to in ISO 10848‑1:2017, 4.5 as being a supporting part of the frame document. It applies to Type B elements as defined in ISO 10848‑1, such as suspended ceilings, access floors, light uninterrupted façades or floating floors. The transmission from one room to another can occur simultaneously through the test element and via the plenum (if any). For measurements made according to this document, the total sound transmission is determined and it is not possible to separate the two kinds of transmission.

ISO 10848 (all parts) specifies measurement methods to characterize the flanking transmission of one or several building components. These measurements are performed in a laboratory test facility or in the field.
The performance of the building components is expressed either as an overall quantity for the combination of elements and junction (such as the normalized flanking level difference and/or normalized flanking impact sound pressure level) or as the vibration reduction index of a junction or the normalized direction-average vibration level difference of a junction.
Two approaches are used for structure-borne sound sources in buildings, a normalized flanking equipment sound pressure level and a transmission function that can be used to estimate sound pressure levels in a receiving room due to structure-borne excitation by service equipment in a source room. The former approach assumes that flanking transmission is limited to one junction (or no junction if the element supporting the equipment is the separating element), and the latter considers the combination of direct (if any) and all flanking transmission paths.
ISO 10848-1:2017 contains definitions, general requirements for test elements and test rooms, and measurement methods. Guidelines are given for the selection of the quantity to be measured, depending on the junction and the types of building elements involved. Other parts of ISO 10848 specify the application for different types of junction and building elements.
The quantities characterizing the flanking transmission can be used to compare different products, or to express a requirement, or as input data for prediction methods, such as ISO 12354‑1 and ISO 12354‑2.

ISO 10848-2:2006 applies to light elements such as suspended ceilings, access floors, light uninterrupted façades or floating floors. The transmission from one room to another can be simultaneous through the test element and via the plenum, if any. With measurements according to ISO 10848-2:2006, the total sound transmission is measured, and it is not possible to separate the two kinds of transmission.
