Overview
ISO 16063-1:1998 - Methods for the calibration of vibration and shock transducers - Part 1: Basic concepts - defines the fundamental concepts, terminology and general methods used to calibrate vibration and shock transducers. It covers calibration of continuous-reading rectilinear acceleration, velocity and displacement transducers, describes primary and comparison calibration approaches, and explains how to express measurement uncertainty. This part is the introductory volume in the ISO 16063 series and establishes the baseline requirements and vocabulary for more detailed procedures in subsequent parts.
Key Topics
- Scope and applicability: Focus on continuous-reading rectilinear transducers; explicitly excludes rotational transducers and most transducers for force, pressure or strain.
- Terms and definitions: Harmonised with ISO 2041 (vibration and shock vocabulary); key defined concepts include sensitivity, direct response, transverse sensitivity ratio (TSR), reciprocal/unilateral transducers, input/output signals.
- Characteristics to be measured:
- Sensitivity (magnitude and phase) across frequency - displacement, velocity and acceleration sensitivities as complex quantities.
- Frequency response and phase response - procedures to detect resonances and phase lag.
- Non-linearity - amplitude distortion, zero shifts after shock, and stop limits.
- Spurious responses such as temperature dependency, cable effects and transverse motion.
- Calibration methods:
- General overview of primary calibration methods (a preferred primary method is identified in clause 5.2.1) and comparison calibration methods (clause 5.3).
- Practical guidance for temperature-response calibrations (e.g., protect standard transducer so its sensitivity remains constant to within 2%; ensure transverse motion
