AHRI 280 (SI/I-P): Requirements for the Qualification of Reverberation Rooms in the 63 Hz Octave Band (Withdrawn 2022)
This standard applies to products rated in the 63 Hz Octave Band (50, 63 and 80 Hz One-Third Octave Bands) where the sound power is determined from measurements made in a reverberation room by using the comparison method as specified per ANSI Standard S12.51/ISO: 3741.
This standard has been withdrawn because the terms and values produced by using it have not been widely accepted and are no longer supported by the member companies.
