Full title and description

ISO 24637:2009 — Space systems — Electromagnetic interference (EMI) test reporting requirements. This International Standard specifies the information and level of detail that shall be included in equipment‑level EMI test reports for spaceflight hardware to support integration analysis, anomaly investigation and any waiver requests following test non‑conformance.

Abstract

ISO 24637:2009 defines minimum content, presentation and augmentation requirements for EMI test reports produced at the equipment level for space systems. Emphasis is placed on supplying sufficient measurement system details, test setup documentation, data presentation and signatures so that results can be reproduced, evaluated for integration, and used when a non‑conformance waiver is requested.

Scope

This standard applies to EMI test reports at the equipment level for spaceflight hardware. It specifies the information required to reproduce tests and to support subsystem and system‑level integration checks, including measurement system details, photographs and drawings of test setups, antenna and probe data, calibration and transfer functions, data presentation formats for radiated and conducted measurements, and documentation of any test deviations or modifications. It does not specify test methods or limits themselves but prescribes how test results and contextual data shall be reported.

Key topics and requirements

• Mandatory report elements: test identification, EUT description and operating modes, signature and contact information for engineers, summary conclusions.
• Measurement system detail: equipment list, calibration certificates, antenna factors, LISN/ probe transfer functions and distances.
• Test setup documentation: photographs, drawings, cabling and interface descriptions to allow reproducibility.
• Data presentation rules: units, resolution, graphic outputs for radiated/conducted emissions and transient events, and reporting conventions for non‑conformances.
• Documentation of modifications and procedure variations, and clear marking of results that apply to flight articles versus test‑only configurations.

Typical use and users

Used by spacecraft EMC/EMI engineers, AIT (assembly, integration & test) teams, test laboratory personnel, systems engineers, project verification managers and procurement/certification authorities. The standard is referenced when preparing EMI test reports for satellite equipment, for assessing integration risk, and when documenting non‑conformance cases or waiver requests to higher‑level verification authorities.

Related standards

Commonly used alongside space engineering EMC standards and test methods such as ECSS‑E‑ST‑20 (Electromagnetic compatibility) and its equipment/subsystem test annexes, national/industry EMI test method standards (for example MIL‑STD‑461 in some programs), and ECSS handbooks and technical reports for EMC verification and reporting practice. These documents provide test methods, limits and system‑level verification requirements; ISO 24637:2009 complements them by prescribing the required content and presentation of the resulting equipment‑level EMI test reports.

FAQ

Q: What is this standard?

A: ISO 24637:2009 is an ISO International Standard that specifies the content and presentation requirements for equipment‑level electromagnetic interference (EMI) test reports for spaceflight hardware.

Q: What does it cover?

A: It covers the minimum information that must appear in EMI test reports (e.g., test identification, EUT configuration and modes, measurement system data, calibration, setup photos/drawings, data presentation and documentation of deviations or modifications). It does not define test procedures or limits.

Q: Who typically uses it?

A: Spacecraft and payload EMC/EMI engineers, AIT/test labs, systems engineers, project verification managers and certification authorities who need consistent, reproducible equipment‑level EMI test documentation.

Q: Is it current or superseded?

A: The 2009 edition (Edition 1) is the published version. ISO records indicate periodic systematic reviews; users should check with their national standards body or ISO for any revision or withdrawal notices before relying on it for regulatory or procurement purposes.

Q: Is it part of a series?

A: ISO 24637:2009 is a standalone document addressing reporting requirements; it sits within the space systems subject area managed by ISO/TC 20/SC 14 and is typically used in combination with other space EMC standards and handbooks (for example ECSS EMC documents and relevant national test method standards).

Q: What are the key keywords?

A: EMI test report, electromagnetic interference, EMC, space systems, equipment‑level reporting, test setup documentation, calibration, LISN, antenna factors.
