标准摘要
[中文适用范围]： 本部分 ISO 10302 涵盖了小空气移动设备（AMD）的振动水平，其安装足迹在全尺寸测试风室（定义于 ISO 10302-1）中小于 0.48 m × 0.90 m，在半尺寸风室中小于 0.18 m × 0.3 m。它涵盖了所有可以安装在测试风室箱的排放面或进气面上并自支撑的 AMD 类型。本部分 ISO 10302 中定义的程序规定了确定小 AMD 在用于信息技术和电信设备的平均结构中会引起的振动水平的方法。本部分 ISO 10302 中规定的方法允许确定所测试的单个 AMD 的感应振动水平。如果对该系列的几个单元进行了测量，这些数据可用于确定该生产系列振动水平的统计值。 [外文原描述]： ISO 10302-2:2011 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 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 ISO 10302‑1. The procedures defined in ISO 10302-2:2011 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 ISO 10302-2:2011 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.
