Full title and description

St ISO 19924-2017 — ISO 19924:2017, "Space systems — Acoustic testing". An international standard giving guidance and a framework for performing acoustic tests on spacecraft hardware (systems, subsystems, modules and units), with emphasis on reverberant-chamber testing, test-system requirements, procedures and criteria for interruption and evaluation.

Abstract

ISO 19924:2017 provides guidance for test providers and interested parties to implement acoustic tests of aerospace systems, subsystems, modules and units for applicable spacecraft programmes. It specifies a framework to meet test and process requirements and acts as a supplement to ISO 15864. The standard describes the acoustic test system, technical requirements and procedures for acoustic tests in reverberant chambers, plus criteria for manual test interruption and evaluation. Requirements are tailorable to fulfil specific test objectives.

General information

• Status: Published (active international standard).
• Publication date: 28 September 2017.

Scope

Applies to acoustic (airborne) environment testing of spacecraft hardware using reverberant chambers. Covers the acoustic test system elements, technical and procedural requirements for generating and measuring specified acoustic fields, conditions for interrupting tests, evaluation and reporting of results. Intended to be used alongside programme-specific test specifications and as a supplement to the general test-method guidance provided in ISO 15864; requirements may be tailored to the objectives of a given test program.

Key topics and requirements

• Framework for planning and implementing reverberant‑chamber acoustic tests on spacecraft hardware.
• Acoustic test system design and performance requirements (sound source, chamber characteristics, diffuse field criteria).
• Specification of test levels, spectra and sweep/steady-state procedures and how to tailor them to programme needs.
• Instrumentation, microphone placement, calibration and data‑acquisition requirements.
• Fixturing, item under test mounting and load/constraints considerations to avoid unrealistic boundary conditions.
• Criteria and procedures for manual test interruption, anomaly handling and evaluation of test results.
• Data analysis, acceptance criteria and required test documentation and reporting.
• Guidance on tailoring, safety and environmental considerations for acoustic test operations.

Typical use and users

Used by space test laboratories, prime contractors and subsystem manufacturers to plan, perform and document acoustic qualification and acceptance tests. Primary users include test engineers, systems and verification engineers, test managers, procurement and quality assurance personnel, and technical authorities responsible for spacecraft environmental verification.

Related standards

Commonly used together with other space and test standards such as ISO 15864 (Space systems — General test methods for spacecraft, subsystems and units), ISO 14620 (spacecraft cleanrooms/contamination), ISO 266 (acoustics — preferred frequencies), IEC 60068-2-65 (acoustically induced vibration test methods), and sector/agency documents (e.g., NASA and ECSS/MIL test criteria and guidance). Programmes often reference ISO 19924 alongside national or mission-specific acoustic test requirements.
