AHRI 530 (SI/2011): Rating of Sound and Vibration for Refrigerant Compressors
This standard applies to external-drive, hermetic, and semi-hermetic refrigerant compressors. The driving mechanism is excluded from the sound and vibration measurements for external-drive refrigerant compressors. However, it is included for semi-hermetic refrigerant compressors because the driving mechanism is an integral part of the compressor assembly, as defined in Section 3.
