ISO 16063的这一部分规定了用于发动机主振动校准的仪器和程序直线加速度计（带或不带放大器），以获得复灵敏度的幅值和相位滞后通过稳态正弦振动和激光干涉测量。它适用于1 Hz至10 kHz的频率范围和0.1 m/s2至10 kHz的动态范围（振幅）1000米/秒（取决于频率）。这些范围包括第2条规定的测量不确定度。校准频率更低大于1 Hz（例如，0,4 Hz，这是其他国际标准中使用的参考频率）和加速度可使用本部分规定的方法3获得小于0.1 m/s2的振幅（例如，在1 Hz时为0004 m/s2）ISO 16063，与适当的低频振动发生器一起使用。方法1（条纹计数法）适用于频率范围为1Hz至800赫兹，在特殊条件下，在更高频率下（参见。第7条）。方法2（最小点法）可以用于800 Hz至10 kHz频率范围内的灵敏度幅度校准（参见第8条）。方法3（正弦近似法）可用于频率范围内的灵敏度和相位校准1 Hz至10 kHz（参见第9条）。方法1和3提供了在不同频率下固定加速度振幅下的校准。方法2要求在固定位移振幅下进行校准（加速度振幅随频率变化）。
This part of ISO 16063 specifies the instrumentation and procedure to be used for primary vibration calibration ofrectilinear accelerometers (with or without amplifier) to obtain magnitude and phase lag of the complex sensitivityby steady-state sinusoidal vibration and laser interferometry.It is applicable to a frequency range from 1 Hz to 10 kHz and a dynamic range (amplitude) from 0,1 m/s2 to1 000 m/s2 (frequency-dependent).These ranges are covered with the uncertainty of measurement specified in clause 2. Calibration frequencies lowerthan 1 Hz (e.g. 0,4 Hz, which is a reference frequency used in other International Standards) and accelerationamplitudes smaller than 0,1 m/s2 (e.g. 0,004 m/s2 at 1 Hz) can be achieved using Method 3 specified in this part ofISO 16063, in conjunction with an appropriate low-frequency vibration generator.Method 1 (fringe-counting method) is applicable to sensitivity magnitude calibration in the frequency range 1 Hz to800 Hz and, under special conditions, at higher frequencies (cf. clause 7). Method 2 (minimum-point method) canbe used for sensitivity magnitude calibration in the frequency range 800 Hz to 10 kHz (cf. clause 8). Method 3(sine-approximation method) can be used for magnitude of sensitivity and phase calibration in the frequency range1 Hz to 10 kHz (cf. clause 9).Methods 1 and 3 provide for calibrations at fixed acceleration amplitudes at various frequencies. Method 2 requirescalibrations at fixed displacement amplitudes (acceleration amplitude varies with frequency).
