- This section specifies the instrumentation and operating procedures for the absolute method calibration of linear accelerometers (with or without amplifiers), as well as methods for obtaining the amplitude and phase shift of the accelerometer's complex sensitivity using steady-state sinusoidal vibration and laser interferometry. The applicable frequency range of this section is 1 Hz ~ 10 kHz, and the dynamic range (amplitude) is 0.1 m/s ~ 1000 m/s (depending on the frequency). The measurement uncertainty specified in Chapter 3 of this part covers the above range. If the calibration frequency is lower than 1 Hz (for example: the reference frequency in other international standards is 0.4 Hz) and the acceleration amplitude is less than 0.1 m/s (for example: 0.004 m/s at 1 Hz), it can be Select a suitable low-frequency shaking table and use Method 3 specified in this section. Method 1 (fringe counting method) is suitable for sensitivity amplitude calibration in the frequency range from 1 Hz to 800 Hz. Under special conditions, it can be used in higher frequency bands (see Chapter 8). Method 2 (minimum point method) is suitable for sensitivity amplitude calibration in the frequency range of 800 Hz to 10 kHz (see Chapter 9). Method 3 (sinusoidal approximation method) is suitable for calibration of sensitivity amplitude and phase shift in the frequency range 1 Hz to 10 kHz (see Chapter 10). Method 1 and Method 3 specify calibration at different frequency points and fixed acceleration amplitudes. Method 2 requires calibration at a fixed displacement amplitude (its acceleration amplitude changes with frequency).
