ISO 24917:2020

Overview

ISO 24917:2020 - Space systems - General test requirements for launch vehicles defines overarching test requirements for launch vehicles equipped with liquid‑propellant engines, covering all development phases and launches from stationary ground-, sea- and air‑based launchers. The second edition (2020) updates terminology, the flight‑vehicle development test structure and the requirements applicability matrix. The standard is intended to harmonize testing practice, reduce development time and cost, and improve launch vehicle quality and reliability.

Key topics and technical requirements

ISO 24917 organizes testing around a clear testing philosophy (objectives, planning, organization and sequencing) and specifies requirements for a comprehensive set of test types and programmes. Major technical topics include:

• Development test programme plan: scope, sequence, objectives, responsibilities, reporting and metrological support.
• Test object definitions and documentation: classification of units, test models and mock‑ups.
• Typical test types (requirements and applicability):
  • Static load, vibration, acoustic and shock tests
  • Cold tests and climatic tests
  • Hot firing tests for liquid‑propellant engines and stages
  • Electromagnetic compatibility (EMC) tests
  • Fire and explosion safety, lightning and static resistance tests
  • Transportability and lifetime tests
  • Integration/check‑out, fuelling and antenna mock‑up tests
  • Flight tests, tests at integration and launch sites, and batch production tests
• Criteria and reporting: test acceptance criteria, typical test report contents and reporting requirements.
• Support plans: communications systems programme plan, safety and reliability assurance, and test metrological support.
• Informative annexes: manufacturing/test category mapping, applicability matrix, typical test report and programme plan contents.

Keywords naturally covered: ISO 24917, launch vehicle testing, space systems, development test programme plan, EMC test, hot firing test, flight test.

Practical applications - who uses it

ISO 24917 is practical for organizations responsible for designing, verifying and fielding launch vehicles, including:

• Launch vehicle manufacturers and prime contractors - to plan and document development and qualification testing.
• Subsystem and engine suppliers - to define unit qualification and acceptance tests.
• Space agencies and launch service providers - for procurement, oversight and acceptance criteria.
• Test engineers, systems engineers and QA/safety teams - to align test methods, reporting and metrology.
• Regulatory and certification bodies - as a reference for harmonized test expectations.

Using ISO 24917 helps reduce program risk, streamline test programmes and ensure traceable, consistent evidence of performance and safety.
