||This international standard specifies a method for measuring airborne noise emitted by small air-moving devices such as those cooling electronic, electrical and mechanical equipment. It describes a method and the test apparatus for determining and reporting the airborne noise emitted by small air-moving devices (AMD) as a function of the airflow and the fan static pressure developed by the air-moving device on the test apparatus. Contents: scope; normative references; definitions (sound power level, air-moving device, fan, test plenum, air-moving device performance curve, point of operation, overall static efficiency of air-moving device, standard air density, frequency range of interest); measurement uncertainty; design and performance requirements for test plenum; installation; operation of air-moving device; measurement procedure; information to be recorded; information to be reported. Illustrations; informative annexes (data formats for presentation, test report).
