BS EN 15657:2017EN 15657:2017 (E) 5 Introduction

31、This European Standard is the result of merging two documents dealing with laboratory characterization of service equipment: former standard EN 15657-1:2009, which was restricted to receivers of mobility much lower than the source mobility, and draft prEN 15657-2, valid for all installation conditio

32、ns. The characterization leads to the determination of the equipment installed structure-borne power, which depends on the source and the receiver, using expressions which have been simplified and approximated in order to use 1/3 octave single equivalent quantities, easily measurable in laboratories

33、 for input data for predictions. The laboratory method for measuring airborne sound, part of former EN 15657-1, is not included in this revised standard. If a measurement of the airborne sound power of the equipment is required, then the methods described in EN ISO 3740 to EN ISO 3747 should be used

34、. BS EN 15657:2017EN 15657:2017 (E) 6 1 Scope 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 123

35、54-5, 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

36、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 equipm

37、ent, 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

38、 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 stair

39、s 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 exp

40、ression 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

41、 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 perfo

42、rmance 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

43、and operating conditions as in measuring using EN 15657. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
