This standard provides information for assessing and presenting the acoustic characteristics of heat exchange
22、rs in operation. This standard also provides information necessary for specifying and selecting the product which best suits the needs of the purchaser. EN 13487:2003 (E) 5 1 Scope This standard specifies methods for uniform assessment and the recording of: the A-weighted sound power level; the soun
23、d power spectrum; a calculation method for an overall average sound pressure level at a given distance. Among these data, the sound power level is the only unambiguous characteristic. This standard is applicable to: forced convection air cooled refrigerant condensers as specified in EN 327; air cool
24、ed liquid coolers “dry coolers“ as specified in EN 1048. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter
