Sound power rating of air-conditioning and air-source heat pump equipment - Part 2: Non-ducted indoor equipment

PUBLISH DATE 1998
ISO 13261-2:1998

This part of ISO 13261 specifies methods for the determination of sound power ratings of air-conditioning and air-source heat pump equipment to be used indoors.

It is applicable to the sound power rating of the indoor sections of non-ducted, factory-made, residential, commercial and industrial air-conditioning and air-source heat pump equipment, which are electrically driven with mechanical compression including free-delivery heat pumps, packaged-terminal air-conditioners and water-source heat pumps.

This part of ISO 13261 includes both an octave-band sound power level rating and a single-number A-weighted overall sound power level rating.

This part of ISO 13261 does not apply to:

  • ducted indoor equipment,
  • chillers,
  • room fan coil units,
  • products with variable speed compressors, or
  • industrial process equipment.
