Methods for the calibration of vibration and shock pick-ups — Part 13: Testing of base strain sensitivity

Lays down detailed specifications for the instrumentation and procedure to be used for base strain sensitivity testing. Applies to rectilinear accelerometers, mainly of the piezoelectric type. Is applicable for the following parameters: reference values – pick-up base radius of curvature: 25 m, base strain: 2,5 × 10^-4; check values – radius of curvature 62,5 m, strain of base 1 × 10^-4; radius of curvature 12,5 m, strain of base 5 × 10^-4.
