ISO 16063的这一部分规定了使用互易法和国际单位制对加速度计进行初级校准所使用的仪器和程序。
它适用于在40Hz至5kHz的频率范围和10m/s2至100m/s2的频率相关振幅范围内校准直线加速度计,并且基于使用电动振动器的线圈作为往复换能器。
如果校准期间与换能器一起使用的信号调节器或放大器已经充分表征,则可以使用ISO 16063的这一部分来获得换能器灵敏度的校准。为了实现这些测量不确定度,已经假设换能器已经与其信号调节器或放大器(其组合在ISO 16063的这一部分中被称为加速度计)组合进行了校准。
This part of ISO 16063 specifies the instrumentation and procedures to be used for primary calibration of accelerometers using the reciprocity method and the SI system of units.
It is applicable to the calibration of rectilinear accelerometers over a frequency range of 40 Hz to 5 kHz and a frequency-dependent amplitude range of 10 m/s2 to 100 m/s 2 and is based on the use of the coil of an electrodynamic vibrator as the reciprocal transducer.
Calibration of the sensitivity of a transducer can be obtained using this part of ISO 16063 provided that the signal conditioner or amplifier used with the transducer during calibration has been adequately characterized. In order to achieve these measurement uncertainties, it has been assumed that the transducer has been calibrated in combination with its signal conditioner or amplifier (the combination of which in this part of ISO 16063 is referred to as the accelerometer).
