ISO 5347 comprises a series of documents dealing with methods for the calibration of vibration and shock pick-ups. This part of ISO 5347 lays down detailed specifications for the instrumentation and procedure to be used for mounting torque sensitivity testing. It applies to pick-ups that are mounted by screws, bolts or other threaded fasteners. The change in calibration factor due to the mounting torque is determined. This part of ISO 5347 is applicable for a mounting torque range of one-half of the specified value, the specified value and twice the value of the specified mounting torque.
