BS EN ISO 10848-2:2017

This standard BS EN ISO 10848-2:2017 Acoustics. Laboratory and field measurement of flanking transmission for airborne, impact and building service equipment sound between adjoining rooms is classified in these ICS categories:

• 91.120.20 Acoustics in building. Sound insulation

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 D_n,f, L_n,f and L_ne0,f only represent the performance with the dimensions for the test specimens described in this document.

This document 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.
