EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN ISO 10848-2 testing. EN ISO 10848 (all parts) specifies measurement methods for characterizing the lateral passage of one or more building components. This document only considers laboratory measurements.
Measured quantities can be used to compare different products or to express a requirement, or as input data for forecasting methods such as ISO 12354-1 and ISO 12354-2. However, the measurands Dn,f, Ln,f and Lne0f represent performance only with the dimensions of test samples described in this standard.
Applies to Type B elements defined in EN ISO 10848‑1 such as suspended ceilings, entrance floors, continuous light façades or floating floors. Conduction from one room to another can occur simultaneously via the test element and the plenum (if applicable). In the measurements made according to this standard, the total sound transmission is determined and it is not possible to distinguish between the two types of transmission.
Except for the façade test, where rooms can be placed on top of each other, the rooms will be on the same level. For access floors and suspended ceilings, the floor plan of the test facility shall be rectangular. When rooms are next to each other, a vibration interruption between the two rooms should be provided to ensure that structure-induced passage from the test facility is negligible.
When a plenum is used, the reverberation time of each room may be affected by sound transmission from the other test room. In such cases, a suitable impermeable plenum barrier should be placed between the edge of the partition wall and the bottom wall of the plenum during reverberation time measurements.
For access floors, the height measured from the surface of the access floor to the surface of the test facility floor should be either 0,3 m or, if this is not possible, the closest possible value should be used. Other heights may be tested if intended for use in practice.
For suspended ceilings, the height measured from the bottom surface of the ceiling to the bottom surface of the test facility ceiling should be between 0,7 m and 0,8 m. Other heights may be tested if intended for use in practice.
