Abstract: 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 ...

Abstract: The products within the scope of this program are air control devices for use in general ventilation and air conditioning systems.
This program shall apply only to complete cataloged series of sizes. It shall not apply ...

Abstract: This ANSI/AMCA standard defines uniform methods for conducting laboratory tests on housed fans to determine airflow rate, pressure, power and efficiency, at a given speed of rotation. This revision adds requirements for ...

Abstract: Provides general information and comments on factors to be considered when designing or specifying installations requiring louvers. Serves as a guide to understanding the various types of louvers available and includes ...

Abstract: Purpose
This part of the AMCA Fan Application Manual includes general information about how fans are tested in the laboratory, and how their performance ratings are calculated and published. It also reviews some of the more important reasons for the "loss" of fan performance that may occur when the fan is installed in an actual...

Abstract: This standard establishes standard methods for calculating consistent fan sound ratings from laboratory test data.
This revision removes catalog statement requirements previously found in AMCA 301-90. Those statements ...

Abstract: Introduction
To apply Sound Power Level Ratings in the design of an air system, the engineer must understand what these ratings are and he must appreciate their limitations. For the many design engineers who are not yet familiar with the techniques of applying acoustical data, this publication may serve as an introduction to th...

Abstract: Purpose
The loudness of a sound as heard by the human ear depends not only upon the overall intensity of the sound, but on its frequency distribution as well. The ear acts as an analyzer, determining ...

Abstract: Provides information on testing and rating power plant fans and covers construction features and related accessories. Sample equipment specifications are included which outline the information a fan manufacturer requires ...
