Specifies vibration levels from small air moving devices (AMDs) with mounting footprints of less than 0,48 m x 0,90 m for the full-size test plenum defined in ISO 10302-1 and less than 0,18 m x 0,3 m for the half-size plenum.

This part of ISO10302 covers vibration levels from small air-moving devices (AMDs) with mounting footprints of less than 0,48m×0,90m for the full-size test plenum defined in ISO10302-1 and less than 0,18m×0,3m for the half-size plenum.

It covers all types of AMDs which can be mounted on, and are self-supported at, the discharge or inlet plane of a test plenum box as specified in ISO10302-1.

The procedures defined in this part of ISO10302 specify methods for determining the vibration levels that a small AMD would induce in an average structure used in information technology and telecommunications equipment. The methods specified in this part of ISO10302 allow the determination of induced vibration levels for the individual AMD that is tested. These data can be used to determine the statistical values of vibration levels for a production series if levels are measured for several units of that series.
