Overview
ISO 16063-31:2009/Amd 1:2025 is an important amendment to the international standard governing methods for the calibration of vibration and shock transducers. Specifically, this amendment enhances Part 31 of the series, focusing on the testing of transverse vibration sensitivity. This update introduces a normative annex detailing the testing methodology using elliptical orbits, providing a more comprehensive and precise approach to evaluating the transverse sensitivity of vibration and shock transducers.
Developed by ISO Technical Committee ISO/TC 108 on Mechanical Vibration, Shock, and Condition Monitoring, this amendment aligns with established procedures and advances the international framework for calibration standards. It ensures the reliable performance and accuracy of transducers used in a variety of industrial, automotive, aerospace, and research applications.
Key Topics
-
Calibration of vibration and shock transducers: This standard discusses precise methods to measure device responses when subjected to transverse vibrations, ensuring accuracy in sensitive measurement instruments.
-
Transverse vibration sensitivity: The amendment focuses on the critical aspect of how transducers respond to vibrations perpendicular to their main sensing axis, an important parameter in accurate data acquisition.
-
Elliptical orbit testing method: A significant addition described in Annex B involves the use of elliptical orbits generated by bi-axial excitation in X and Y directions. This technique allows for the testing of transducer sensitivity over multiple axes and phases of vibration.
-
Mathematical formulation: The amendment provides detailed formulas (B.1 to B.10) describing acceleration components, output response, sensitivity ellipses, and sensitivity lines, enhancing the precision in quantifying transverse sensitivity.
-
Special case for circular orbits: The amendment notes circular orbit motion as a special case of elliptical motion, where the two perpendicular vibration components have equal magnitudes and are 90 degrees out of phase, simplifying sensitivity calculations.
