Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of

This first edition of ISO 16063-34 cancels and replaces ISO 5347-17:1993, which has been technically
revised. The main changes are as follows:
— a method for the determination of complex sensitivity using a laser interferometer has been added;
— a method for the determination of complex sensitivity using a reference transducer inside the
temperature chamber has been added;
— a procedure for testing phase changes has been added;
— Annex A for the determination of the achievement time of the setpoint temperature for the device
under test has been added;
— Annex B for the evaluating uncertainty caused by temperature tolerance has been added.

Introduction
The purpose of this document is to establish the procedures for testing the complex sensitivity of
vibration transducers at fixed temperatures in the temperature range from –190 °C to 800 °C and
frequency range from 10 Hz to 3 kHz.
The three methods described in this document allow the determination of the complex sensitivity or
temperature response of complex sensitivity of a transducer to sinusoidal vibration in the temperature
chamber.
Principles, procedures, and uncertainties of calibrations such as a comparison to a reference transducer
or an absolute measurement by laser interferometer are given in this document. Calibrations are
carried out using one of the three methods, depending on the different principles to be used and the
temperature and frequency range limitations.
INTERNATIONAL STANDARD ISO 16063-34:2019(E)
Methods for the calibration of vibration and shock
transducers —
Part 34:
Testing of sensitivity at fixed temperatures
1 Scope
This document details specifications for the instrumentation and methods to be used for testing fixed
temperature sensitivity of vibration transducers. It applies to rectilinear velocity and acceleration
transducers.
The methods specified use both a comparison to a reference transducer and an absolute measurement
by laser interferometer.
This document is applicable for a frequency range from 10 Hz to 3 kHz (method-dependent), a dynamic
2 2
range from 1 m/s to 100 m/s (frequency-dependent) and a temperature range from –190 °C to 800 °C
(method-dependent). Although it is possible to achieve these ranges among all the described systems,
generally each has limitations within them.
Method 1 (using a laser interferometer) is applicable to magnitude of sensitivity and phase calibration
in the frequency range 10 Hz to 3 kHz at fixed temperatures (see Clause 7). Method 2 (using a reference
transducer inside a chamber whose temperature limit is –70 °C to 500 °C) can be used for magnitude
of sensitivity and phase calibration in the frequency range 10 Hz to 1 kHz at fixed temperatures (see
Clause 8). Method 3 (using a reference transducer outside the chamber) can only be used for the
determination of the temperature response of complex sensitivity over a certain temperature range
(see Clause 9).
NOTE Method 1 and Method 2 can provide the deviation of complex sensitivity over a certain temperature
range if the calibration is also done at the reference temperature (room temperature 23 °C ± 5 °C).
To ensure the consistency of the use and test condition, the transducer, its cable and the conditioning
amplifier are intended to be considered as a single unit and tested together.

3 Terms and definitions
For the purpose of this document, the terms and definitions given in ISO 2041 and the following apply.

3.1
temperature response
sensitivity of the transducer at a given frequency as a function of its steady-state temperature
Note 1 to entry: Temperature response is measured at specified frequencies within the rated frequency range of
the transducer.
Note 2 to entry: In general, the sensitivity is a complex-valued function quantity and can be expressed in terms of
its magnitude and phase.
4 Uncertainty of measurement
The limits of the uncertainty of measurement in terms of expanded uncertainty applicable to this
document are as follows.
a) For the magnitude of sensitivity:
— when using a laser interferometer (Method 1): 0,5 % of the measured value at reference
conditions; 1 % of the measured value outside reference conditions,
— when using a reference transducer
