This standard specifies methods for uniform assessment and the recording of: - the A-weighted sound power level; - the sound 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 cooled liquid coolers "dry coolers" as specified in EN 1048.
