ÖNORM EN ISO 10848-2:2007-04

Заменен
Acoustics - Laboratory measurement of the flanking transmission of airborne and impact noise between adjoining rooms - Part 2: Application to light elements when the junction has a small influence (ISO 10848-2:2006) (consolidated version)
ISO 10848 specifies measurement methods to be performed in a laboratory test facility in order to
characterize the flanking transmission of one or several building components.
The measured quantities may be used to compare different products, or to express a requirement, or as input
data for prediction methods, such as EN 12354-1 and EN 12354-2.
This part of ISO 10848 is specifically referred to in ISO 10848-1:2006, 4.4, as being a supporting part of the
frame document.
This part of ISO 10848 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 this part of ISO 10848, the total sound
transmission is measured, and it is not possible to separate the two kinds of transmission. The measured
quantities Dn,f and Ln,f depend on the actual dimensions of the test specimen.
A light element is defined in ISO 10848-1:2006, Clause 3.
Die Norm beschreibt Messverfahren, die in dafür ausgelegten Prüfständen durchzuführen sind, um die akustischen Eigenschaften eines oder mehrerer Bauteile hinsichtlich der Flankenübertragung festzustellen. Diese akustischen Eigenschaften können zum Vergleich verschiedener Produkte, beim Festlegen einer Anforderung oder als Größe bei Vorhersageverfahren, wie z.B. gemäß der EN 12354-1 und der EN 12354-2, verwendet werden.
