EN 16603-10-03:2014 (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 test sequence 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 and test conditions, tolerances and accuracy;
• 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;
• 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 test, for each model, is
defined after 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 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 tolerances, and test
accuracies,
• General requirements for development tests pertinent to the start of the
qualification test programme,
NOTE 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,
• In-orbit testing,
• Testing of space segment subsystems,

SIST EN 16603-10-03:2014
EN 16603-10-03:2014 (E)
NOTE 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 For verification of flight or ground software,
ECSS-E-ST-40 and ECSS-Q-ST-80 apply.
• Qualification testing of two-phase heat transport equipment,
NOTE For 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.

Terms, definitions and abbreviated terms
3.1 Terms from other standards
For the purpose of this standard, since ECSS-S-ST-00-01 has not been published
at the time of the publication of this standard, the introduction part of the ECSS
Glossary has been copied here.
For the purpose of this standard; the terms and definitions from ECSS-S-ST-00-01
apply, and in particular the following:
flight model
lifetime
protoflight model
qualification model
space segment element
space segment equipment
space segment subsystem
structural model

ECSS-S-ST-00-01C defines the highest-level system within a space project - i.e.
the one at the mission-level - as the “Space System”. The breakdown of a typical
space system and the definition of standard terms for the constituent levels
within the breakdown are given below (see Figure 3-1 and subsequent
definitions).
For this standard only, the terms for the Space Segment are defined in 3.1.
Since any definition always includes some ambiguity and in order to allow the
user of the testing standard to clearly classify the item under test in the right
category (i.e. Space segment Element, or equipment the table below give a list of
example (see Figure 3-2). This table, however, is not exhaustive
