振动与冲击传感器校准方法 第21部分：振动比较法校准
Application Summary AI generated
This standard specifies the procedure for calibrating vibration transducers (e.g., accelerometers) by comparing their output directly to a reference transducer under controlled sinusoidal vibration. It is applied in metrology laboratories and industrial testing facilities to ensure accuracy in vibration measurement equipment used for machinery health monitoring, structural dynamics analysis, and product qualification testing.
