DIN EN ISO 10848-2:2016-10

ISO 10848 specifies measurement methods to be performed in a laboratory test facility or in the field in order to characterize the flanking transmission of one or several building components. This part of ISO 10848 considers only laboratory measurements. The measured quantities may 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 standard. This part of ISO 10848 is referred to in ISO 10848-1, 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 part of ISO 10848, the total sound transmission is determined, and it is not possible to separate the two kinds of transmission.
