ASA S12.11-2003/Part 1ISO 10302:1996 (R2008) PDF

This Nationally Adopted International Standard specifies in detail a laboratory method for determining and reporting the airborne noise emissions of small air-moving devices used primarily for cooling electronic equipment, such as computer and business equipment. To provide compatibility with measurements of noise emitted by such equipment, this Nationally Adopted International Standard uses the noise emission descriptors and sound power measurement methods of ANSI S12.10- 2002/ISO 7779:1999. The descriptor of overall noise emission of the air-moving device under test is the A-weighted sound power level. The one-third-octave-band sound power level is the detailed descriptor of the noise emission. Octave band sound power levels may be provided in addition to the one-third-octave-band sound power levels. ANSI S12.11-2003 Part 2 describes measurement of structure-borne noise generated by air-moving devices.
