Space engineering testing requirements and standards presented by ECSS for space projects and applications. The foreword explains ECSS as a cooperative effort to define what shall be accomplished, allowing organizational structures and methods to evolve without rewriting standards. The document includes a formal disclaimer limiting warranties and liabilities. The change log highlights the transition from ECSS-E-ST-10-03C (1 June 2012) to ECSS-E-ST-10-03C Rev.1 (31 May 2022), detailing main updates across scope, thermal tests, solar array and panel testing, pressure testing, input tolerances and measurement uncertainties, and new or modified test requirements.

Space engineering Testing ECSS Secretariat ESA-ESTEC Requirements & Standards Section Noordwijk, The Netherlands Foreword This Standard is one of the series of ECSS Standards intended to be applied together for the management, engineering, product assurance and sustainability in space projects and applications. ECSS is a cooperative effort of the European Space Agency, national space agencies and European industry associations for the purpose of developing and maintaining common standards. Requirements in this Standard are defined in terms of what shall be accomplished, rather than in terms of how to organize and perform the necessary work. This allows existing organizational structures and methods to be applied where they are effective, and for the structures and methods to evolve as necessary without rewriting the standards. This Standard has been prepared by the ECSS-E-ST-10-03 TA Task Force, reviewed by the ECSS Executive Secretariat and approved by the ECSS Technical Authority. Disclaimer ECSS does not provide any warranty whatsoever, whether expressed, implied, or statutory, including, but not limited to, any warranty of merchantability or fitness for a particular purpose or any warranty that the contents of the item are error-free. In no respect shall ECSS incur any liability for any damages, including, but not limited to, direct, indirect, special, or consequential damages arising out of, resulting from, or in any way connected to the use of this Standard, whether or not based upon warranty, business agreement, tort, or otherwise; whether or not injury was sustained by persons or property or otherwise; and whether or not loss was sustained from, or arose out of, the results of, the item, or any services that may be provided by ECSS.

Changes with respect to ECSS-E-ST-10-03C (1 June 2012) are identified with revision tracking.
Main changes are:
• Scope: Clarification on applicability perimeter, including not covering space vehicle constellation
• Thermal Tests:
o New and more clear definitions, (thermal vacuum test, thermal test at room pressure and thermal test at mission pressure, they are no more in the Glossary),
o Thermal Ambient Test not used and substituted by Thermal Test at mission pressure,
o Alternative methods are addressed as reference to the Handbook
o “thermal” word in thermal parameters (cycles, levels, gradient and soon) changed as “temperature”,
o Test for switch on capability at equipment level was updated to cover test at maximum and minimum temperature,
o New requirement on power status during thermal tests at equipment level and parameter monitoring.
• Test on solar arrays and panel:
o overall align of the Testing Standard with the new version of ECSS-EST-20-08,
o new requirements for solar array performance tests in addition to flasher test,
o additional requirement for after storage phase,
o functional tests requirements at equipment level during thermal tests for solar arrays are now expanded.
• Pressure test:
o Overall alignment with new version of ECSS-E-ST-32-02,
o requirements on proof pressure test rephrased to enlarge the objective of the test.
• Input test Tolerance and measurement uncertainties:
o “tolerance” definition was substituted by “test input tolerance”whereas “accuracy of measurement” was deleted and substituted by | | | “measurement uncertainty” to be in accordance with actual
International Standards,
o some requirements rephrased to avoid confusion between"uncertainty" (quantitat

FAQs

What is the purpose of this ECSS testing standard?

It defines testing requirements for space projects and applications in terms of what shall be accomplished, enabling existing methods to be applied and evolved without rewriting the standards.

What does the disclaimer state about warranties and liability?

The document provides no warranties, including that the contents are error-free, and limits ECSS liability for damages arising from use of the standard.

Which main areas were changed in ECSS-E-ST-10-03C Rev.1 compared with ECSS-E-ST-10-03C?

Key updates include scope clarification, revisions to thermal test definitions and monitoring requirements, enhanced solar array/panel testing requirements, updates to pressure test phrasing, and changes to input test tolerance and measurement uncertainty handling, plus updates to other test methods.
