ISO 16063-33:2017 specifies a method, procedures and the specifications for an apparatus to be used for testing the magnetic field sensitivity of vibration and shock transducers. It is applicable to all kinds of vibration and shock transducers. ISO 16063-33:2017 is applicable for a reference test sinusoidal magnetic field having a root mean square (r.m.s.) value more than 10?3 T at 50 Hz or 60 Hz. Typically, a test magnetic field of 10?2 T at 50 Hz or 60 Hz is used. ISO 16063-33:2017 is primarily intended for those who are required to meet internationally standardized methods for the measurement of magnetic field sensitivity under laboratory conditions. NOTE 1 T (tesla) = 1 Wb/m2.

Abstract

Overview

ISO 16063-33:2017 - Methods for the calibration of vibration and shock transducers - Part 33: Testing of magnetic field sensitivity specifies laboratory procedures and apparatus requirements for measuring how vibration and shock transducers respond to external sinusoidal magnetic fields. The standard applies to all types of vibration/shock transducers and covers reference test fields at 50 Hz or 60 Hz with r.m.s. magnetic flux densities above 10⁻³ T (typically 10⁻² T). It is intended for calibration laboratories, manufacturers and metrology institutes needing internationally consistent magnetic‑sensitivity measurements.

Key topics and requirements

Test principle: Determine the transducer’s maximum output in a reference magnetic field and express magnetic field sensitivity S as S = X_B,max / B, where X_B,max is the transducer maximum output (r.m.s.) and B is the test magnetic flux density (r.m.s., in tesla).
Magnetic field sensitivity tester: A dedicated tester uses a pair of coils (two coils) symmetrically mounted with distance D equal to coil radius R (D = R). The test platform is non‑ferromagnetic, rotatable and centred between coils.
Apparatus specs
- Coil arrangement: Two coils rotated horizontally; field uniformity within ±3% near centre.
- Platform: Mass > 50 × transducer mass; allow ≥180° rotation around the transducer’s sensitivity axis.
- Vibration isolation: Eigenfrequency
