This European Standard specifies methods for estimating the structure-borne sound power produced in buildings by services equipment (sources) from measurements under laboratory conditions. The data can be used as explained in Annex D, as input for EN 12354-5, or under certain conditions for EN ISO 12354 2, to calculate the sound pressure levels produced by the same equipment when installed in buildings. The data can also be used to compare the performance of products as explained in Annex E. As for the document predicting the structure-borne sound levels produced in the buildings by service equipment (EN 12354-5), this European Standard covers water supply and sanitary installations, mechanical ventilation, heating and cooling devices, service equipment, lifts, rubbish chutes, boilers, blowers, pumps, motors and other auxiliary service equipment, such as motor driven car park doors; it can also be applied to other vibrating equipment attached to or installed in buildings. This standard is so far restricted to steady-state vibrating sources. This revised European Standard: - specifies laboratory measuring methods for determining the source input data required to calculate the source installed power, i.e. the equipment free velocity, the equipment blocked force and the equipment mobility; - applies to equipment, which can be connected to isolated plates in the laboratory. For equipment, such as pipe systems or impacted lightweight stairs [16], which are connected to at least two building elements (wall and floor), a coupled reception plate system is specified, which requires the use of a power substitution method. The later method can also be used in situ when the equipment, such as lifts, can only be tested in situ; - defines the expression of the source installed structure-borne power for any source-receiver mobility conditions, including lightweight and heavyweight receiving building elements. This power is used as input data in EN 12354-5, which predicts the sound pressure level generated by the source installed in situ in a building; - defines a method to calculate the total structure-borne sound power generated by the equipment fictively mounted on two sets of reference test plates (respectively of low mobility and of high mobility); the two results will inform the manufacturers on the difference in the equipment performance between these two common but very different situations; - does not specify any method for the measurement of the source airborne sound power. If measurements of the equipment airborne sound power are required, then refer to EN ISO 3740 to EN ISO 3747 and use the same source mounting conditions and operating conditions as in measuring using EN 15657.
