Overview

ISO 15261:2004/Amd 1:2016 is an amendment to the ISO 15261 vocabulary for vibration and shock generating systems. This amendment updates key terminology used to describe vibration test equipment (shakers) and, in particular, replaces subclause 3.12 with a clarified definition of the transverse motion ratio. The document is maintained by ISO/TC 108 (Mechanical vibration, shock and condition monitoring), Subcommittee SC 6.

Key topics

• Vocabulary for vibration and shock generating systems: standardized terms that ensure consistent communication across test labs, manufacturers and regulators.
• Transverse motion ratio (T): the amendment replaces the earlier text with a precise definition:
  • T is the maximum ratio of a vibration quantity (acceleration, velocity or displacement) measured in a direction perpendicular to the operating axis of a vibration generator to the specified amplitude along the operating axis under sine excitation.
  • The transverse component is calculated from two orthogonal axes in the plane perpendicular to the operating axis (root-sum-square of the two orthogonal transverse components).
  • T is normally expressed as a percentage and is frequency-dependent.
• Scope of quantities: applies equally to acceleration, velocity and displacement measures used in vibration testing.
• Editorial and copyright details: the amendment follows ISO/IEC Directives and notes possible patent declarations.

Applications

• Shaker specification and acceptance testing: use the transverse motion ratio to evaluate off-axis motion of vibration generators and to set acceptance criteria when procuring shakers.
• Test setup and fixture design: engineers use T to assess fixture alignment, mounting quality, and to minimize unwanted transverse responses that can invalidate test results.
• Laboratory quality assurance: vibration test labs rely on standardized vocabulary to document test reports, ensure repeatability, and demonstrate conformance to client or regulatory requirements.
• Industry sectors: applicable in aerospace, automotive, defense, electronics, and any industry performing environmental vibration or shock testing.

Who should use this standard

• Vibration and shock test engineers
• Laboratory managers and QA personnel
• Shaker and instrument manufacturers
• Standards committees and certification bodies
• Procurement and technical specification authors

Related standards

• Other ISO/TC 108 mechanical vibration and shock publications and vocabulary documents (refer to ISO/TC 108 for related standards and guidance).

Keywords: vibration and shock generating systems, ISO 15261 amendment, transverse motion ratio, vibration testing, shaker performance, mechanical vibration vocabulary, sine excitation, frequency-dependent.

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
