1 Scope
This standard addresses the requirements for performing verification by testing of
space segment elements and space segment equipment on ground prior to launch. The
document is applicable for tests performed on qualification models, flight models
(tested at acceptance level) and protoflight models.
The standard provides:
-
• Requirements for test programme and test management,
-
• Requirements for retesting,
-
• Requirements for redundancy testing,
-
• Requirements for environmental tests,
-
• General requirements for functional and performance tests,
NOTE 1 Specific requirements for functional and performance tests are not part of this standard since they are defined in the specific project documentation.
-
• Requirements for qualification, acceptance, and protoflight testing including qualification,
acceptance, and proto-fight models’ test margins and duration,
-
• Requirements for test factors, test condition, test input tolerances, and measurement uncertainties,
-
• General requirements for development tests pertinent to the start of the qualification
test programme,
NOTE 2 Development tests are specific and are addressed in various engineering discipline
standards.
-
• Content of the necessary documentation for testing activities (e.g. DRD).
Due to the specific aspects of the following types of test, this Standard does not
address:
-
• Space system testing (i.e. testing above space segment element), in particular the
system validation test,
-
• Testing peculiarities of space vehicles constellations,
-
• In-orbit testing,
-
• Testing of space segment subsystems,
NOTE 3 Tests of space segment subsystems are often limited to functional tests that, in some
case, are run on dedicated models. If relevant, qualification tests for space segment
subsystems are assumed to be covered in the relevant discipline standards.
-
• Testing of hardware below space segment equipment levels (including assembly, parts,
and components),
-
• Testing of stand-alone software,
NOTE 4 For verification of flight or ground software, ECSS‑E‑ST‑40 and ECSS‑Q‑ST‑80 apply.
-
• Testing of two-phase heat transport equipment,
NOTE 5 For acceptance and qualification testing of two-phase heat transport equipment, ECSS‑E‑ST‑31‑02 applies.
-
• Tests of launcher segment, subsystem and equipment, and launch facilities,
-
• Tests of facilities and ground support equipment,
-
• Tests of ground segment.
This standard may be tailored for the specific characteristic and constrains of a
space project in conformance with ECSS‑S‑ST‑00. Annex D gives guidelines for performing this tailoring.
