ISO 16063-44 is a safety standard on the calibration of field vibration calibrators. Since vibration calibrators are used for testing and checking vibration sensors and measuring instruments at the site of their operation, they are transportable and battery operated.
ISO 16063-44 specifies the instrumentation and procedure to be used for performing calibration of field vibration calibrators (FVCs). Calibration intervals are determined based on periodic examinations of the operational condition of the FVC.
NOTE: ISO 16063-44 is not applicable to FVCs used for the calibration of transducers. These are covered by ISO 16063-21.
ISO 16063-44 on FVC calibration is useful for:
ISO 16063 comprises a series dealing with methods for the calibration of vibration and shock transducers. ISO 16063-44 focuses on FVCs. In this context, FVCs is mainly used for in situ checks of vibration and shock transducers providing sine wave vibration at known frequency and magnitude under field conditions.
The FVC acts as a calibrated vibration source for in situ checks of transducer sensitivity. Operational frequency and acceleration RMS value of FVCs are usually 160 Hz or 159,2 Hz, and 3,16 m/s2, 9,81 m/s2 or 10 m/s2, respectively, which are widely accepted as reference conditions.
There are also FVCs with selectable acceleration magnitudes and frequencies. Using the calibration procedure described by ISO 16063-44, the acceleration generated by an FVC can be traceable, through the chain of calibration.
ISO 16063-44 guidelines assists you with the configuration and application of field vibration calibrators.
