Full title and description

ISO 8626:1989/Amd 1:2016 — Servo-hydraulic test equipment for generating vibration — Method of describing characteristics — Amendment 1. This is a one-page amendment published in 2016 that updates and clarifies parts of the original ISO 8626:1989 text used to describe and declare the performance characteristics of servo-hydraulic vibration test equipment.

Abstract

This amendment to ISO 8626:1989 provides technical and editorial changes to the method by which manufacturers and test laboratories describe key characteristics of servo-hydraulic vibration generating equipment. The content is compact (one page) and is intended to be read together with the original 1989 standard; it clarifies definitions and declaration requirements so that users can compare and specify equipment more reliably.

General information

• Status: Published
• Publication date: 29 November 2016 (published as Amendment 1, 2016)
• Publisher: International Organization for Standardization (ISO)
• ICS / categories: 17.160 — Vibrations, shock and vibration measurements
• Edition / version: Amendment 1 to ISO 8626:1989 (Edition: Amd 1, 2016)
• Number of pages: 1 (amendment document)

Scope

The amendment applies only to ISO 8626:1989 and is intended to update, clarify or correct specific provisions of that International Standard. ISO 8626 covers methods for describing the performance characteristics of servo-hydraulic systems used to generate linear vibration (e.g., rated force, frequency range, permissible static load, limits for displacement/velocity/acceleration, transverse motion). The amendment itself does not replace the full standard; it must be used in conjunction with ISO 8626:1989.

Key topics and requirements

• Clarification of terminology and declaration requirements for servo-hydraulic vibration equipment.
• Guidance on which characteristic parameters should be reported by manufacturers (rated force, frequency range, permissible static load, displacement/velocity/acceleration limits, resonance information).
• Improved precision in measurement or calculation statements used when declaring system performance so users can compare different systems.
• Editorial corrections and small technical updates to the original 1989 text (amendment is primarily concise and targeted).
• Reference to ISO/TC 108/SC 6 committee practice for vocabulary and measurement conventions where appropriate.

Typical use and users

Used by manufacturers of servo-hydraulic vibration test systems, test-laboratory engineers, equipment purchasers and specifiers, standards committees, and quality/acceptance engineers who need consistent, comparable declared performance data for vibration test systems. It is primarily a normative reference when preparing equipment data sheets and procurement specifications.

Related standards

Relevant companion standards include the original ISO 8626:1989 (base standard), ISO 5344 (electrodynamic vibration generating systems — performance characteristics and its amendments), ISO 15261 (vibration and shock generating systems — vocabulary and its amendments), and calibration standards such as ISO 16063 (methods for calibration of vibration and shock transducers). These documents together provide vocabulary, performance declaration and calibration practices for vibration-generating systems.

FAQ

Q: What is this standard?

A: ISO 8626:1989/Amd 1:2016 is Amendment 1 (published 2016) to the International Standard ISO 8626:1989, which covers the method of describing performance characteristics of servo-hydraulic vibration test equipment.

Q: What does it cover?

A: The amendment updates and clarifies elements of the original 1989 standard related to how manufacturers and laboratories describe and declare key equipment characteristics (force ratings, frequency range, permissible static loads, limits for displacement/velocity/acceleration, transverse motion, resonance information). It is a short (one-page) technical and editorial update that must be read alongside ISO 8626:1989.

Q: Who typically uses it?

A: Equipment manufacturers, test-lab engineers, procurement/specification writers, quality managers and standards committees involved in mechanical vibration and shock testing use this amendment to ensure consistent and comparable declaration of servo-hydraulic system performance.

Q: Is it current or superseded?

A: The amendment was published in 2016 and is a published update to ISO 8626:1989. Users should consult ISO records or their national standards body to confirm whether the base standard or subsequent revisions have been consolidated or superseded since 2016; the amendment itself remains the formal Amd 1:2016 document to be used with ISO 8626:1989.

Q: Is it part of a series?

A: It is part of the body of standards maintained by ISO/TC 108 (Mechanical vibration, shock and condition monitoring), Subcommittee SC 6 (Vibration and shock generating systems). Related series include standards for electrodynamic and other types of vibration generators (for example ISO 5344) and vocabulary/calibration standards (ISO 15261, ISO 16063).

Q: What are the key keywords?

A: Key keywords are: servo-hydraulic, vibration test equipment, performance characteristics, rated force, frequency range, transverse motion ratio, displacement, velocity, acceleration, ISO 8626, amendment 2016.
