Abstract: Based on the research of uncertainty source and magnitude, the experimental results and experience, the measurement uncertainty of magnitude and phase shift of sensitivity is analyzed and evaluated according to ISO 16063-11:1999 for high precision low frequency accelaromter with amplifier at Secondary Standard for Vertical Low frequency Vibration. Therefore, it will provide a reference data to emending the nation vibration dissemination system. The relative expanded uncertainties of magnitude and phase shift of sensitivity are 0.30% and 0.1961616; at reference condition (16Hz), 0.66% and 0.6561616; over the complete frequency range from 0.1Hz to 120Hz.
