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 patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents ).

This document was prepared by Technical Committee ISO/TC 108, Mechanical vibration, shock and condition monitoring.

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.

A list of all parts in the ISO 16063 series can be found on the ISO website.

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.

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 range from 1 m/s² to 100 m/s² (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).

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.
