European Foreword
This document (EN 16603-10-03:2022) has been prepared by Technical
Committee CEN/CLC/JTC 5 “Space”, the secretariat of which is held by DIN.
This standard (EN 16603-10-03:2022) originates from ECSS-E-ST-10-03C Rev.1.
This European Standard shall be given the status of a national standard, either
by publication of an identical text or by endorsement, at the latest by April 2023,
and conflicting national standards shall be withdrawn at the latest by April 2023.
Attention is drawn to the possibility that some of the elements of this document
may be the subject of patent rights. CEN [and/or CENELEC] shall not be held
responsible for identifying any or all such patent rights.
This document supersedes EN 16603-10-03:2014.
The main changes with respect to EN 16603-10-03:2014 are listed below:
• 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 so
on) 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-E-
ST-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,
5

---------------------- Page: 7 ----------------------
SIST EN 16603-10-03:2022
EN 16603-10-03:2022 (E)
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" (quantitative evaluation) and "error" (quantitative, but
unknown),
o Table 4-2 now addresses typical values for test centres and no more
requirements.
• Sine burst test replaced Transient test at space segment equipment level,
because rarely used, and it is merged with Transient at space segment
element level.
• Microvibration and Audible noise:
o new requirements for microvibration in particular to cover signal
measurement and background noise measurement and background noise
mitigation actions,
o requirements on Audible noise were changed, and some deleted, at
equipment level to account for the tight dependence on the mounting
structure.
• Polarity test: new requirement for polarity test of non-critical modes.

This document has been prepared under a standardization request given to CEN
by the European Commission and the European Free Trade Association.
This document has been developed to cover specifically space systems and has
therefore precedence over any EN covering the same scope but with a wider
domain of applicability (e.g. : aerospace).

EN 16603-10-03:2022 (E)
Introduction
The requirements on the systems engineering process are gathered in ECSS-E-
ST-10; while specific aspects are further elaborated in dedicated standards, in
particular: ECSS-E-ST-10-06, ECSS-E-ST-10-02 and the present standard (ECSS-
E-ST-10-03)
In the System Engineering branch (ECSS-E-10) this standard aims at a consistent
application of on ground testing requirements to allow proper qualification and
acceptance of space products
Experience has demonstrated that incomplete or improper on ground testing
approach significantly increase project risks leading to late discovery of design
or workmanship problem(s) or in-orbit failure(s).
Testing is part of the system engineering process as defined in ECSS-E-ST-10.
This starts at the early phase of the mission when defining verification process in
terms of the model philosophy and sequences of tests and ends at the last testing
phase prior launch.
In the level of decomposition of a space system, this standard addresses the
requirements for space segment element and space segment equipment.

The document is organised such that:
• clause 4 provides requirements for overall test programme, test
management test conditions, test input tolerances and measurement
uncertainties;
• clause 5 provides requirements for Space segment equipment;
• clause 6 provides requirements for Space segment element;
• clause 7 provides requirements for Pre-launch testing.

Clauses 5 and 6 are organised as follows:
• general requirements for the products under test applicable to all models
(clause 5.1 or 6.1);
• requirements applicable to qualification model (clause 5.2 or 6.2);
• requirements applicable to acceptance model (clause 5.3 or 6.3);
• requirements applicable to protoflight model (clause 5.4 or 6.4);
• detailed implementation requirements (clause 5.5 or 6.5);

In the clause providing requirements for each model (i.e. clauses 5.2, 5.3, 5.4, 6.2,
6.3 and 6.4), the first table of the clause:
• lists all types of test and defines their applicability and conditions;
• links to the second table of the clause that defines tests level and duration;
7

---------------------- Page: 9 ----------------------
SIST EN 16603-10-03:2022
EN 16603-10-03:2022 (E)
• provides reference to the clause defining the detailed implementation
requirements for the given test (clause 5.5 or 6.5).

For space segment equipment, the required sequence of tests, for each model, is
defined by tailoring the two tables in clause 5.2, 5.3 or 5.4.
Since testing activities are part of the overall verification activities, test
documentation to be produced (DRD’s) are either specified in the ECSS-E-ST-10-
02 (case of the test report) or in this document.
Annex D gives guidelines for performing the tailoring of this standard as well as
the generation of the compliance and verification matrices.

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,
9

---------------------- Page: 11 ----------------------
SIST EN 16603-10-03:2022
EN 16603-10-03:2022 (E)
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.
