目的本标准的目的是为指定、制造、使用和维护风机的个人定义适当的风机平衡质量和运行振动水平。它是附录F中列出的一系列标准和出版物的一部分，涵盖了与风机设计、制造和使用相关的重要方面。范围本标准适用于商业供暖、通风和空调中常见的带有刚性转子的风机；工业过程应用；矿井/隧道通风应用；以及发电应用。一些申请被排除在外。该标准仅用于覆盖风扇的平衡或振动，不考虑风扇振动对人员、设备或过程的影响。

PurposeThe purpose of this standard is to define appropriate fan balance quality and operating vibration levels to individuals who specify, manufacture, use and maintain fans. It is part of a series of standards and publications listed in Annex F that cover important aspects related to fan design, manufacture and use.ScopeThis standard covers fans with rigid rotors generally found in commercial heating, ventilating and air conditioning; industrial process applications; mine/tunnel ventilation applications; and power generation applications. Some applications are excluded. This standard is intended to cover only the fan's balance or vibration and does not consider the effect of fan vibration on personnel, equipment or processes.
