ISO 16063-42:2014 specifies the instrumentation and procedure to be used for the accurate calibration of seismometer sensitivity using local gravitational acceleration (local Earth's gravitation, local value for the acceleration due to the Earth's gravity) as a reference value.
It is intended generally to be applied to a servo-type accelerometer with/without a velocity output, which usually has a mass position output in the category of a wide-band seismometer with a bandwidth from 0,003 Hz to 100 Hz. The method specified enables the user to obtain static sensitivity for the seismometers up to 10-5 m/s2 (which corresponds to 1 mGal and approximately 1 ppm of the gravitational acceleration).
The intended end-usage of the seismometer to be applied is: a) measurement and observation for the earth science including geophysics usage, b) measurement and observation for disaster prevention, such as detecting the precursor of a land slide, c) diagnosis for the soundness of a building structure and foundation soil in civil engineering, d) observation for nuclear-test detection.
