DNV ECMA 275 PDF

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

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 ISO 10302-1. Some guidance is given for non-self-supporting AMDs.

The procedures defined in this Standard 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 Standard allow the determination of induced vibration levels for the individual AMD that is tested. These data may be used to determine the statistical values of vibration levels for a production series if levels are measured for several units of that series.
