ISO 16063-32:2016规定了通过冲击激励测试加速度计频率和相位响应的仪器和程序的详细规范。它适用于阻尼比小于临界值且频率范围高达150 kHz的压电式、压阻式和可变电容式加速度计。 该方法假定，在满足ISO 5348中规定的加速计机械安装建议且参考冲击球的质量至少超过加速计质量三倍的条件下，通过该方法获得的被测加速计的频率和相位响应是安装加速计的最佳可能特性加速计正在测试中。 通过这种方法获得的被测加速度计的相位响应被认为是加速度计的某种“虚拟”特性，假定在0 Hz的频率下，输入和输出信号之间存在零相移。 注1:用户应注意，对于现场应用中的同一加速计，频率和相位响应可能不同，这取决于测试结构的质量和符合性以及安装方法。该方法仅允许对加速度计的频率和相位响应进行定性评估。 注2:与适当特性的动态范围相比，用户不会试图获得被测加速计频率和相位响应初始部分的更好分辨率。通过这种方法获得的加速度计的频率和相位响应的最佳用途是为上述特性的初始部分获得最佳拟合线。

ISO 16063-32:2016 lays down detailed specification for instruments and procedures of testing the frequency and the phase response of accelerometers by means of shock excitation. It applies to the accelerometers of the piezoelectric, piezoresistive and variable capacitance types with the damping ratio less than critical and in the frequency range up to 150 kHz. The method presumes that the frequency and the phase responses of the accelerometer under test gained by this method are the best possible characteristics for the mounted accelerometer on the condition that the recommendations for mechanical mounting of accelerometer stated in ISO 5348 are fulfilled and that the mass of the reference shock ball exceeds at least three times the mass of the accelerometer under test. Phase response of the accelerometer under test gained by this method is considered to be some "virtual" characteristic of accelerometer presuming that there is zero phase shift between the input and output signals at a frequency of 0 Hz. NOTE 1 It is intended that the user be aware that for the same accelerometer in the field application, the frequency and the phase responses might be different, depending on the mass and compliance of the test structure and the method of mounting. The method allows just a qualitative evaluation of the frequency and the phase response of accelerometers. NOTE 2 It is intended that the user does not try to get better resolution of the initial parts of the frequency and phase responses of the accelerometer under test than the dynamic range of the adequate characteristic provides it. The best use of the frequency and the phase responses of the accelerometer gained by this method are to get the best fit lines for the initial parts of the mentioned characteristics.
