This verification system table is applicable to the transfer of measurement values of vibration measuring instruments, and stipulates the composition and use of the national reference standard for vibration. It specifies the procedure for transferring vibration measurement values from the national reference standard to working measuring instruments through metrological standard instruments, and provides corresponding expanded uncertainties and basic verification methods. When conducting calibration, this verification system table can also be used as a basis for traceability of measurement values.
This verification system table uses the amplitude and phase (φ) (in °) of vibration frequency f〖KG-*4〗 (Hz), vibration acceleration a〖KG-*4〗 (m/s2), velocity v〖KG-*4〗 (m/s), and displacement d〖KG-*4〗 (m) as the main physical quantities to describe vibration motion.
