The Air Movement and Control Association International (AMCA International) announced that the Board of
Standards Review of the American National Standards Institute (ANSI) recently approved the following document:
ANSI/AMCA STANDARD 300-08, Reverberant Room Method for Sound Testing of Fans.
This standard establishes a method of determining the octave band sound
power levels of a fan. The method is reproducible when all requirements of the
method are met. This standard applies to fans of all types and sizes. It is
limited to the determination of airborne sound emission for the specified
setups. Vibration is not measured, nor is the sensitivity of airborne sound emission
to vibration effects determined. The test setup requirements in this standard
establish the laboratory conditions necessary for a successful test. Rarely will it be possible to meet these requirements in a field
situation. This standard is not intended for field measurements.
This
edition revises the duct end reflection corrections a small amount. The revised corrections now reflect documented sources. Also, the
physical requirements for the reverberant room were revised to harmonize them
with international standards. Several other minor changes were made to make the
standard more understandable, reveals the associations press release. |
