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 ).

The committee responsible for this document is ISO/TC 108, Mechanical vibration, shock and condition monitoring, Subcommittee SC 3, Use and calibration of vibration and shock measuring instruments.

This first edition of ISO 16063-16 cancels and replaces the first edition of ISO 5347-5:1993, which has been technically revised.

This corrected version of ISO 16063-16:2014 incorporates the following corrections:

• Table 1, last row, + sign added before 240°
• Paragraph 2, after Formula (2), k = 1 changed to k = 2 and the uncertainty value adapted.
• Formula (5) has been corrected, and a degree sign has been added after 180 in the explanation.
• Formula (7) has been corrected, and in the explanation, the superfluous rows for a_α0 and a_α180 have been removed.
• In Figure 1, the equal sign has been removed.
• Keys have been added under Figures 2 and 3.
• In Formula (A.2), the 8 above the summation sign has been removed.
• In the explanation to Formula (A.2), u_i has been replaced by u(x_i ).
• In Formula (A.3) and in its explanation, u(e_g ) has been replaced by u(a_g ).
• In addition, the following list of parts has been updated:

1 Scope

This part of ISO 16063 specifies the instrumentation and procedure to be used for performing primary calibration of accelerometers using Earth's gravitation. It is applicable to rectilinear accelerometers with DC (zero hertz frequency) response, such as straingauge, piezoresistive, variable capacitance, and servo accelerometer types.

This part of ISO 16063 is applicable to the calibration of the magnitude of the sensitivity, referenced to the acceleration due to the local gravitation at 0 Hz.

With the use of appropriate calibration equipment, this part of ISO 16063 can be applied to the calibration of the magnitude of the sensitivity, referenced to fractional parts of the acceleration due to the local gravitation at 0 Hz. The specification of the instrumentation used contains requirements on environmental conditions, as well as specific requirements for the apparatus to be used.

The sensitivity obtained using this part of the ISO 16063 standard for accelerometers with a DC response can be used over the flat part of the low-frequency range of the accelerometer. The degree of flatness of the applicable frequency range is intended to be taken into account in the uncertainty of measurement (UoM).

This part of ISO 16063 is applicable to reference standard accelerometers and working standard accelerometers, as well as complete acceleration measurement chain (accelerometer complete with amplifier and readout unit).
