Full title and description

St ISO 21980-2020 — Space systems — Evaluation of radiation effects on Commercial‑Off‑The‑Shelf (COTS) parts for use on low‑orbit satellite. This standard gives guidance and methods to evaluate radiation-induced failure modes and quantify suitability of COTS electronic and electromechanical parts for use in low Earth orbit (LEO) satellite applications.

Abstract

ISO 21980:2020 defines evaluation methods for environmental and radiation tests applicable to COTS parts intended for LEO satellites. It covers the principal radiation effects of concern (total ionizing dose, single‑event effects, and displacement damage), describes useful test types and test selection criteria, and provides guidance for interpreting test results when qualifying COTS components for small satellite and other LEO missions.

Scope

Provides methods and recommendations for evaluating radiation effects on Commercial‑Off‑The‑Shelf (COTS) parts intended for use in low‑orbit satellites. The standard addresses which radiation effects should be considered for LEO operations (total ionizing dose, single‑event effects, displacement damage), describes relevant laboratory and environmental tests, and gives guidance on test planning, data interpretation and reporting to support selection and acceptance of COTS parts for satellite systems.

Key topics and requirements

• Identification of relevant radiation effects for LEO: total ionizing dose (TID), single‑event effects (SEE), and displacement damage (DD).
• Recommended test types and procedures for characterizing TID, SEE and DD susceptibilities.
• Guidance on selecting representative test samples, test levels and test environments appropriate to LEO missions.
• Data reporting and interpretation practices to support engineering decisions (pass/fail criteria, margins, and derating considerations).
• Risk‑based use of COTS parts including acceptance testing, life‑cycle considerations and documentation needed for procurement and qualification.

Typical use and users

Used by satellite and payload designers, spacecraft systems engineers, parts engineers, procurement and quality assurance teams, environmental and radiation test laboratories, and COTS component suppliers who need to assess and document the radiation performance of components intended for LEO satellites (including small satellites and CubeSats). Typical uses include pre‑selection screening, qualification testing, supplier evaluation, and generating test evidence to support mission risk assessments.

Related standards

Related ISO deliverables from the ISO/TC 20/SC 14 space systems portfolio (for example standards addressing CubeSats and other space product assurance topics) are commonly used alongside ISO 21980 when developing test programs and procurement requirements. Examples of related space systems standards published in the same portfolio include ISO 17770 (CubeSats) and other ISO/TC 20/SC 14 outputs.
