Full title and description

St ISO 26871-2020 — Space systems — Explosive systems and devices. This International Standard specifies design, performance, safety, interface and verification requirements for explosive and pyrotechnic systems and devices intended for use on spacecraft, launch vehicles and associated ground support equipment.

Abstract

ISO 26871:2020 provides requirements and guidance to ensure that explosive systems and devices used in space applications perform their intended functions reliably and safely throughout design, integration, test and operational phases. Topics include background and applicability, properties, design (including debris and reliability considerations), mission and functionality requirements, prevention of unintended functioning, environmental survival, interface and mechanical/electrical/thermal requirements, and verification/qualification.

General information

• Status: Active (current international standard).
• Publication date: October 2020 (published 19 October 2020 in the ISO catalogue entry).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 49.140 — Space systems and operations.
• Edition / version: Second edition (2020), replacing ISO 26871:2012.
• Number of pages: 77 pages (English original).

Scope

Applies to explosive systems and devices used on spacecraft, launch vehicles and related ground support equipment. The standard covers requirements for design and analysis, functional and safety requirements, reliability and confidence levels, unwanted-response prevention, mission-specific considerations, environmental and survivability criteria, interfaces (internal and external), and mechanical, electrical and thermal requirements together with verification and qualification testing. It is intended for use where explosive/pyrotechnic functions (for example separation, initiation, actuation or controlled release) are needed in space applications.

Key topics and requirements

• Definitions, terminology and symbols relevant to explosive systems and devices for space.
• Design requirements: architecture, dimensioning, debris mitigation and containment.
• Reliability, confidence levels and performance allocation for mission success.
• Prevention of unintended function and safety measures for handling, integration and operation.
• Environmental and survival conditions: thermal, mechanical, shock (pyroshock), vacuum and ageing considerations.
• Interface requirements: functional, internal and external interfaces with spacecraft and ground support equipment.
• Mechanical, electrical and thermal requirements, including EMI/EMC considerations where applicable.
• Verification, qualification and testing regimes (type and acceptance tests, inspections and documentation).
• Programmatic and mission tailoring: guidance for tailoring requirements to specific project constraints and safety policies.

Typical use and users

Primary users include spacecraft and launch vehicle systems engineers, pyrotechnic/actuation device designers, safety and reliability engineers, integration and test teams, procurement and quality assurance staff, test laboratories and regulatory/safety authorities involved in spaceflight hardware that employs explosive or pyrotechnic components. The standard is used during requirement definition, design, qualification testing, integration and operations planning.

Related standards

Relevant complementary or related documents include the earlier ISO 26871:2012 (superseded), ECSS explosive/pyrotechnic standards such as ECSS‑E‑ST‑33‑11 (Explosive systems and devices), and national/agency specifications for pyrotechnics (for example NASA pyrotechnic system specifications). Standards on space system safety, interface control, vibration/pyroshock testing and environmental testing (ISO/ECSS/agency documents) are also commonly used alongside ISO 26871.

FAQ

Q: What is this standard?

A: ISO 26871:2020 (St ISO 26871-2020) is an international standard that defines requirements for explosive and pyrotechnic systems and devices used in space applications, covering design, safety, interfaces and verification.

Q: What does it cover?

A: It covers terminology; applicability; properties; detailed design requirements (including debris and reliability); mission and functionality specs; prevention of unintended function; survival and environmental conditions; interface, mechanical, electrical and thermal requirements; and verification/qualification tests and documentation.

Q: Who typically uses it?

A: Systems and design engineers, pyrotechnic device manufacturers, test and integration teams, quality and safety engineers, launch providers and space agencies that develop, procure or certify explosive/pyrotechnic hardware for spacecraft and launch systems.

Q: Is it current or superseded?

A: ISO 26871:2020 is the current (active) edition published in October 2020 and replaces the 2012 edition. Users should check with their national standards body or ISO catalogue for any amendments or later confirmations.

Q: Is it part of a series?

A: It is part of the body of ISO standards for space systems (ICS 49.140) and is used alongside other space engineering and safety standards (ISO, ECSS and agency specifications) rather than as a numbered multi‑part series. Projects commonly apply it together with related ECSS and agency (e.g., NASA) pyrotechnic and space safety standards.

Q: What are the key keywords?
