As for the document predicting the structure borne sound levels produced in the buildings by service equipment (EN 12354-5:2009), this European standard covers sanitary installations, mechanical ventilation, heating and cooling, service equipment, lifts, rubbish chutes, boilers, blowers, pumps and other auxiliary service equipment, and motor driven car park doors; it can also be applied to other equipment attached to or installed in buildings. However, this standard is so far restricted to stationary sources. This revised 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; - defines the expression of the source installed power for any source-receiver mobility conditions, including lightweight and heavyweight receiving building elements. This power is used as input data in EN 12354-5:2009, which predicts the structure borne sound pressure level generated by the source installed in situ in a building; - defines a method to calculate the structure borne sound power generated by the equipment fictively mounted on two reference test rigs (respectively heavyweight and lightweight) ; the two results will inform the manufacturers on the difference in the equipment performance between these two common but very different situations; - does not now 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, 47 and use the same source mounting conditions and operating conditions as in measuring using prEN 15657. Throughout this standard the frequency range is limited to the 21 1/3 octave bands with mid-frequencies from 50 Hz to 5000 Hz.
