UNE-EN ISO 10848-2:2018

ISO 10848 specifies measurement methods to be performed in a laboratory test facility or in the fieldin order to characterize the flanking transmission of one or several building components. This part ofISO 10848 considers only laboratory measurements.The measured quantities may be used to compare different products, or to express a requirement, oras input data for prediction methods, such as ISO 12354-1 and ISO 12354-2. However, the measuredquantities Dn,f, Ln,f and Lne0,f only represent the performance with the dimensions for the test specimensdescribed in this standard.This part of ISO 10848 is referred to in ISO 10848-1, 4.5, as being a supporting part of the framedocument. It applies to Type B elements as defined in ISO 10848-1, such as suspended ceilings, accessfloors, light uninterrupted façades or floating floors. The transmission from one room to another canoccur simultaneously through the test element and via the plenum (if any). For measurements madeaccording to this part of ISO 10848, the total sound transmission is determined, and it is not possible toseparate the two kinds of transmission.
