Full title and description

ISO 23670:2021 — Space systems — Vibration testing. Provides guidance and technical requirements for planning and performing vibration tests on spacecraft, subsystems and units, including methods to avoid over‑testing (notably the force‑limiting approach).

Abstract

This international standard specifies vibration test methods, test‑system and instrumentation requirements, control strategies and acceptance criteria for space hardware. It includes guidance on test specification, tolerances, specimen configuration, response measurement, force measurement devices, shaker and fixture requirements, test procedures (preparation, implementation and post‑test activities), and interruption/handling rules. The document supports tailoring of technical requirements to meet specific test objectives.

Scope

Applies to ground vibration testing of spacecraft, subsystems and units for space applications. Covers development of the test specification, selection of control strategy and control points, required test equipment (shaker, fixtures, force measurement devices, measurement and control systems), instrumentation and data acquisition, procedures for resonance surveys, sine and random vibration testing, test success criteria, and procedures for handling interruptions, anomalies and post‑test verification. The standard is intended for use by test providers, test engineers and programme stakeholders and allows tailoring of requirements to specific objectives and hardware configurations.

Key topics and requirements

• Test specification and tolerances (define levels, durations, axes and pass/fail criteria).
• Control strategy and control point selection (acceleration vs. force control; notching/force limiting approaches to avoid over‑testing).
• Resonance survey and modal checks (pre/post low‑level surveys to identify modes and detect nonlinear behaviour).
• Shaker, fixture and force measurement device (FMD) requirements and calibration.
• Measurement system, instrumentation and data acquisition requirements (response measurement points, channels and sampling).
• Test procedures: preparation, safety checks, implementation (low‑level → full‑level → verification), and post‑test inspections/functional checks).
• Test interruption and anomaly handling (criteria for stopping, documentation and retest rules).
• Tailoring: provisions to adapt technical requirements to specific mission/test objectives and to mitigate over‑testing risks.

Typical use and users

Used by spacecraft manufacturers, subsystem and instrument developers, environmental test facilities, launch integrators, and qualification/verification engineers. Typical uses include qualification and acceptance vibration testing, proto‑flight verification, workmanship checks and correlation of analytical models with measured dynamic responses. Test houses and programme/system‑level test planners rely on the standard to ensure consistent, flight‑representative vibration tests and to reduce risk of over‑testing through force limiting and control best practices.

Related standards

Commonly used alongside other space and environmental test standards such as ECSS‑E‑ST‑10‑03 (Space engineering — Testing), NASA GEVS / GSFC‑STD‑7000 (General Environmental Verification Standard) and relevant IEC/ISO environmental test series (for example IEC 60068 series for vibration and shock test methods). Project teams often align ISO 23670 guidance with ECSS and agency‑specific verification standards when defining qualification and acceptance programmes.

FAQ

Q: What is this standard?

A: ISO 23670:2021 is an international standard that defines guidance and technical requirements for vibration testing of spacecraft, subsystems and units, including methods (such as force limiting) to reduce the risk of over‑testing.

Q: What does it cover?

A: It covers test specification, tolerances, control strategies and control points, specimen configuration and instrumentation, shaker/fixture/FMD requirements, test procedures (preparation, execution and post‑test), acceptance criteria, and handling of test interruptions and anomalies. The requirements are written to be tailorable to mission‑specific objectives.

Q: Who typically uses it?

A: Spacecraft and subsystem designers, environmental test laboratories, verification and qualification engineers, launch integrators and procurement/test managers who plan and execute vibration qualification and acceptance campaigns.

Q: Is it current or superseded?

A: ISO 23670:2021 is the current published (first) edition (published September 2021). Users should confirm during procurement or program planning that no later revision has been released.

Q: Is it part of a series?

A: It is a standalone ISO standard developed under ISO/TC 20/SC 14 (Space systems) addressing vibration testing; it is used in conjunction with broader space testing and environmental verification standards (ECSS, NASA GEVS, IEC test methods) but is not presented as a numbered multipart ISO series.

Q: What are the key keywords?

A: Key keywords include vibration testing, force limiting, shaker, fixture, force measurement device (FMD), random vibration, sine vibration, resonance survey, test control, qualification and acceptance.
