This International Standard lays down rules for the presentation of important characteristics for electro-mechanical shock and vibration pick-ups (seismic pick-ups), the electrical outputs of which are known functions of the uniaxial, multiaxial or angular accelerations, velocities or displacements of objects the motions of which are being measured. It is intended as a guide to instrument manufacturers for indicating characteristics of their pick-ups and as a help to users in selecting a particular type of pick-up or preparing performance specifications. The intention is to ensure that the user receives an adequate description of the characteristics of any particular pick-up. Throughout this International Standard, shock and vibration pick-ups will be referred to simply as "pick-ups".
