Overview
ISO 16063-22:2005/Amd 1:2014 is an amendment to the international standard detailing methods for the calibration of vibration and shock transducers, specifically focusing on shock calibration by comparison to a reference transducer. This updated document built on the original 2005 edition expands on the shock pulse duration and dynamic range applicability, providing enhanced guidelines that ensure traceability and accuracy in shock calibration practices. The standard is developed and maintained by ISO Technical Committee ISO/TC 108, which specializes in mechanical vibration, shock, and condition monitoring.
The amendment revises key parameters such as acceleration peak magnitudes, pulse durations, and uncertainty ranges while referencing the primary calibration method ISO 16063-13:2001 for high-precision shock calibrations. It provides detailed methodologies and conditions under which shock calibration can be reliably performed using secondary and primary calibration techniques.
Key Topics
-
Shock Calibration Range
The amendment extends the applicability to shock pulse durations ranging from 0.025 ms to 8.0 ms with a dynamic acceleration range of 100 m/s² up to 2,000 km/s² (time dependent).
-
Traceability to Primary Calibration
Larger accelerations exceeding 100 km/s² and shorter pulse durations than 0.05 ms can be calibrated with traceability to the primary shock calibration outlined in ISO 16063-13 using laser interferometry.
-
Reference Transducers and Measurement Methods
Calibration is performed by comparing the test transducer to a reliable reference transducer using methods compliant with ISO 16063-13 specifications.
-
Uncertainty Limits
The amendment provides updated tables defining uncertainty limits for various shock calibrator apparatus including pendulum, drop ball, pneumatic pistons, and Hopkinson bars.
-
Dispersion in Bars
Annex C discusses wave dispersion phenomena in slender bars used in calibration (e.g., Hopkinson bar). It explains the impact of frequency-dependent wave speeds on calibration accuracy and sets requirements for bar dimensions and wave propagation.
-
Measurement Resolution
Recommendations call for transducer output measurements to have a resolution of at least 12 bits, preferably 16 bits, enhancing data accuracy.
-
Pulse Duration Recommendations
Suggested minimum pulse duration follows the relation t ≥ 5/f_shock,res, where f_shock,res is the shock measurement's effective bandwidth, ensuring proper signal resolution.
