制造厂家为使电机、电器或机械设备能可靠而又充分发挥性能的运行所作出的规定数值。如额定电压、额定功率、额定转矩、额定容量等。使用中一般不得超过额定值。

• The voltage rating of these resistors must be at least equal to the test voltage.

  这些电阻器的电压额定值必须至少等于测试电压。

• If the insulation is to be as well protected after it is reduced, the arrester rating must be correspondingly reduced.

  若绝缘减少后仍同样地能被保护，那末避雷器额定值也必须相应降低。

• Do not exceed the speed in revolutions per minute (RPM) rating of any grinding wheel or disk.

  不可超过任何砂轮片或转盘的每分钟转数（RPM）额定值。

• ASME capacities are steam pressure ratings and do not reflect the CSA temperature relieving capacity of the valves for selection purposes.

  ASME流容是蒸汽压力额定值，并不代表阀门在所选择的用途中CSA温度泄放能力。

• Nameplate rating is only a guide to transformer application, and should only be used as a first step in the selection process.

  铭牌额定值仅是变压器应用的一个指导，只是选择过程的第一步。

• When electric power coupling transformer at input current is less than rated value, public winding can be also overload.

  电力自耦变压器在其输入电流均小于额定值时，其公共绕组也可能过负荷。

• Ratings are in accordance with the recommended standards adopted by the Steam Heating Equipment Manufacturers Association.

  额定值符合美国蒸汽加热设备制造商协会所采用的推荐标准。

• Be sure to use capacitors within the specified values by checking the voltage waveform, current waveform, and frequency applied to them.

  使用前请先检查电容器两端的电压波形、电流波形和频率是否在额定值内。

• When the air pressure of the inner tube rises to a rated value, the one-way valve is closed, and the inflation process is completed.

  内胎气压升高到额定值时，单向阀关闭，充气过程即结束。
