Space engineering - Verification

This Standard establishes the requirements for the verification of a space system product.
It defines the fundamental concepts of the verification process, the criteria for defining the verification strategy and specifies the requirements for the implementation of the verification programme. It includes also the list of the expected documentation (i.e. Document requirements definitions, DRDs).
This Standard is intended to apply to different products at different levels from a single equipment to the overall system.
Discipline related verification aspects are complemented in Standards specific to those disciplines.
For verification process for SW the following standards are considered fully sufficient for development of these items:
-   ECSS-E-ST-40 Space engineering - Software
-   ECSS-Q-ST-80 Space product assurance - Software product assurance
Detailed requirements for Testing are covered in the ECSS E-ST-10-03.
This standard does not specifically address Validation of space products as a separate process, since product Verification is performed against requirements that also address the suitability of the product to fulfil the needs of its intended use. As such, Validation is achieved through the Verification process provided adequate requirements are placed on the product.
It is recognised that testing and analysis also occur during the product development process, but they are not addressed by this standard as they are not formal requirement verification activities in the sense of the customer-supplier relationship.
The guidelines on verification are provided in the associated handbook ECSS-E-HB-10-02A.
The requirements on the systems engineering process are gathered in ECSS-E-ST-10 "System Engineering"; specific aspects of the SE process are further elaborated in dedicated standards, in particular: ECSS-E-ST-10-06 "Technical Specification", ECSS-E-ST-10-02 "Verification" (the present standard), and ECSS-E-ST-10-03 "Testing". These standards are based on the same principles, process and documentation model.
The applicability of each these standards can therefore not be considered in isolation from the others
This standard may be tailored for the specific characteristic and constraints of a space project in conformance with ECSS-S-ST-00.

Raumfahrttechnik - Verifikation

Ingénierie spatiale - Vérification

La présente norme définit les exigences applicables à la vérification d'un produit du système spatial.
Elle définit les concepts fondamentaux du processus de vérification, ainsi que les critères pour définir la stratégie de vérification, et spécifie les exigences de mise en oeuvre du programme de vérification. Elle inclut en outre la liste de la documentation attendue (définitions des exigences documentaires ou DRD).
La présente norme est destinée à s'appliquer à différents produits et à différents niveaux, depuis un équipement particulier jusqu’à l'ensemble du système.
Les aspects de la vérification associés à des disciplines particulières sont traités par des normes spécifiques.
Concernant le processus de vérification des logiciels, les normes suivantes sont considérées comme suffisantes pour le développement de ces éléments :
-   ECSS-E-ST-40 Ingénierie spatiale - Logiciels
-   ECSS-Q-ST-80 Assurance produit des projets spatiaux - Assurance produit logiciel
Les exigences d'essai détaillées sont décrites dans l'ECSS E-ST-10-03.
La présente norme ne traite pas de manière spécifique de la validation des produits spatiaux en tant que processus distinct, car la vérification des produits est effectuée en fonction d'exigences liées à la capacité du produit à satisfaire les besoins associés à son utilisation prévue. C'est pourquoi la validation est effectuée dans le cadre du processus de vérification, sous réserve que le produit s'accompagne des exigences appropriées.
Il est admis que les essais et analyses interviennent également au cours du processus de développement du produit. Ils ne sont cependant pas traités dans la présente norme, dans la mesure où ils ne sont pas considérés comme des activités formelles de vérification des exigences au sens de la relation client-fournisseur.
Les lignes directrices relatives à la vérification sont fournies dans le manuel associé ECSS-E-HB-10-02A.
Les exigences relatives au processus d'ingénierie des systèmes sont réunies dans l'ECSS-E-ST-10, « Ingénierie système » ; les aspects spécifiques au processus d'IS sont décrits de façon plus détaillée dans des normes dédiées, à savoir : ECSS-E-ST-10-06 « Spécification technique de besoin », ECSS-E-ST-10-02 « Vérification » (la présente norme) et ECSS-E-ST-10-03 « Vérification par essai ». Ces normes se fondent sur les mêmes principes, les mêmes processus et le même modèle de documentation.
L'applicabilité de chacune de ces normes ne peut donc être envisagée de manière indépendante.
La présente norme peut être adaptée aux caractéristiques et contraintes spécifiques d'un projet spatial conformément à l'ECSS-S-ST-00.

Vesoljska tehnika - Preverjanje

Ta standard določa zahteve za preverjanje izdelka vesoljskega sistema.
Opredeljuje temeljne koncepte postopka preverjanja, merila za določanje strategije preverjanja in določa zahteve za izvajanje programa preverjanja. Vključuje tudi seznam pričakovane dokumentacije (tj. dokumente z definicijami zahtev, DRD-je).
Ta standard se uporablja za različne izdelke na različnih ravneh od posameznega kosa opreme do celotnega sistema.
Vidiki preverjanja, povezani s posamezno disciplino, so dopolnjeni s standardi, specifičnimi za te discipline.
V okviru postopka preverjanja programske opreme naslednji standardi povsem zadostujejo za razvoj teh postavk:
– ECSS-E-ST-40 Vesoljska tehnika - Programska oprema
– ECSS-Q-ST-80 Zagotavljanje varnih proizvodov v vesoljski tehniki - Zagotavljanje varne programske opreme
Podrobne zahteve za preskušanje so zajete v standardu ECSS E-ST-10-03.
Ta standard se posebej ne nanaša na preverjanje vesoljskih izdelkov v smislu ločenega procesa, saj se preverjanje izdelkov izvaja glede na zahteve, ki obravnavajo tudi primernost izdelka za izpolnitev potreb njegove predvidene uporabe. Preverjanje se tako izvaja s postopkom preverjanja, v katerem mora izdelek izpolnjevati ustrezne zahteve.
Znano je, da se preskušanje in analiza izvajata tudi med procesom razvoja izdelka, vendar ju ta standard ne zajema, ker nista formalni dejavnosti preverjanja zahtev v smislu razmerja med stranko in dobaviteljem.
Smernice za preverjanje so navedene v pripadajočem priročniku ECSS-E-HB-10-02A.
V standardu ECSS-E-ST-10 »Sistemski inženiring« so zajete zahteve za postopek sistemskega inženiringa; posebni vidiki postopka sistemskega inženiringa so natančneje določeni v namenskih standardih, točneje: ECSS-E-ST-10-06 »Tehnična specifikacija«, ECSS-E-ST-10-02 »Preverjanje« (ta standard) in ECSS-E-ST-10-03 »Preskušanje«. Navedeni standardi temeljijo na enakih načelih, procesu in modelu dokumentiranja.
Zato uporabnosti posameznega standarda ni mogoče presojati ločeno od ostalih standardov.
Ta standard se lahko prilagodi posameznim lastnostim in omejitvam vesoljskega projekta v skladu s standardom ECSS-S-ST-00.

European Foreword

This document (EN 16603-10-02:2018) has been prepared by Technical Committee CEN/CLC/TC 5

“Space”, the secretariat of which is held by DIN (Germany).
This document (EN 16603-10-02:2018) originates from ECSS-E-ST-10-02C 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 May 2019, and conflicting national standards shall be

withdrawn at the latest by May 2019.

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 14725:2003.

The main differences between EN 14725:2003 (that was based on ECSS-E-10-02A) and this standard

are:

• Restructuring of the document following, in particular: moving of the guidelines in the

associated Handbook, inclusion of an introductive clause on the Verification principles,

structuring of the requirement clauses in line with the verification process flow as

summarized in the principles.

• Clarification on standard applicability to different types of products (e.g. launcher,

transportation system, ground segment, GSE).
• Clarification of the verification vs. validation coverage.

• Moving of detailed test requirements to EN 16603-1003 (based on ECSS-E-ST-10-03C)

“Testing” including AIT Plan, Test Specification and Test Procedure DRDs.

• Introduction of risk assessment and mitigation plan concerning those requirements not

verified by test.

• Clarification on the applicability of verification by similarity as analysis method in

relationship to different types of products (requirement 5.2.2.3c)

• Clarification on product categories vs. heritage and relevant qualification requirements (clause

5.2.4.2)

• Clarification on in-orbit stage verification activities, in particular the relationship with the

commissioning (clause 5.2.4.5)

• Inclusion of a requirement concerning the verification database delivery in electronic form

(requirement 5.4.1c)
• Introduction of “status of compliance” in the VCD data (VCD DRD)

• Simplification of DRD’s number and content

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).

According to the CEN-CENELEC Internal Regulations, the national standards organizations of the

following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,

Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of

Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,

Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia,

Scope

This Standard establishes the requirements for the verification of a space system

product.

It defines the fundamental concepts of the verification process, the criteria for

defining the verification strategy and specifies the requirements for the
implementation of the verification programme. It includes also the list of the
expected documentation (i.e. Document requirements definitions, DRDs).

This Standard is intended to apply to different products at different levels from

a single equipment to the overall system.
Discipline related verification aspects are complemented in Standards specific
to those disciplines.
For verification process for SW the following standards are considered fully
sufficient for development of these items:
• ECSS-E-ST-40 Space engineering – Software
• ECSS-Q-ST-80 Space product assurance - Software product assurance
Detailed requirements for Testing are covered in the ECSS E-ST-10-03.
This standard does not specifically address Validation of space products as a
separate process, since product Verification is performed against requirements

that also address the suitability of the product to fulfil the needs of its intended

use. As such, Validation is achieved through the Verification process provided
adequate requirements are placed on the product.
It is recognised that testing and analysis also occur during the product
development process, but they are not addressed by this standard as they are
not formal requirement verification activities in the sense of the customer-
supplier relationship.
The guidelines on verification are provided in the associated handbook ECSS-E-
HB-10-02A.
The requirements on the systems engineering process are gathered in ECSS-E-
ST-10 “System Engineering”; specific aspects of the SE process are further
elaborated in dedicated standards, in particular: ECSS-E-ST-10-06 “Technical
Specification”, ECSS-E-ST-10-02 “Verification” (the present standard), and
ECSS-E-ST-10-03 “Testing”. These standards are based on the same principles,
process and documentation model.
The applicability of each these standards can therefore not be considered in
isolation from the others

This standard may be tailored for the specific characteristic and constraints of a

space project in conformance with ECSS-S-ST-00.

Verification principles
4.1 Verification process
4.1.1 Verification objectives
The overall objective of verification is to demonstrate, through a dedicated
process, that the deliverable product meets the specified requirements.
A satisfactory completion of the verification process is the basis for a
contractual acceptance (as defined in ECSS-S-ST-00-01) of the product by the
Customer.
The objectives of the Verification process are as follows:
• to demonstrate the qualification of design and performance, as meeting
the specified requirements at the specified levels;
• to ensure that the product is in agreement with the qualified design, is
free from workmanship defects and acceptable for use;
• to confirm product integrity and performance at particular steps of the
project life cycle (e.g. launch, commissioning, mission events and
landing).
• to confirm that the overall system (including tools, procedures and
resources) is able to fulfil mission requirements;
4.1.2 Verification activities
The verification process activities consist of planning, execution, reporting,
control and closeout as summarized in Figure 4-1.

4.2 Verification planning
4.2.1 Verification approach
To reach the verification objectives the verification approach is established in
early phases of a project by analyzing the requirements to be verified, taking
into account:
• design peculiarities and constraints,
• qualification status of candidate solutions (product category),
• availability and maturity of verification tools,
• verification (including test) methodologies,
• ground segment and in orbit constraints for the in-orbit stage (including
commissioning),
• programmatic constraints, and
• cost and schedule.
In generating the verification approach, the supplier conducts the following
steps:
 Identify “what” are the products and requirements subject of the
verification process;
 Identify “How” to verify them by considering the methods stated
in the technical specification
 Identify “When” to implement by applying the chosen verification
strategy.
These steps are generally conducted in an iterative process based on technical,
cost and schedule considerations, ensuring that the approach is agreed by both
the supplier and the customer.
4.2.2 Verification methods
The verification is executed by one or more of the following verification
methods: test, analysis, review of design and inspection. This list shows the
order of precedence that, in general, provides more confidence in the results.
4.2.3 Verification levels
The verification is performed incrementally at different product decomposition
levels. The number and type of verification levels depends upon the complexity
of the project and on its characteristics.
The usual verification levels for a space product are equipment, subsystem,
element, segment and overall system.
---------------------- Page: 14 ----------------------
SIST EN 16603-10-02:2019
EN 16603-10-02:2018 (E)
4.2.4 Verification stages
The verification process is implemented in subsequent verification stages along
the project life cycle.
The stages depend upon project characteristics and identify a type of
verification. The verification stages are qualification, acceptance, pre-launch,
in-orbit (including commissioning) and post-landing.
4.2.5 Model philosophy
The verification by test is implemented on the selected models chosen for the
project.
Model philosophy is defined by means of an iterative process which combines
programmatic constraints, verification strategies and the integration and test
programme, taking into account the development status of the candidate design
solution.
4.2.6 Verification tools

The verification tools to be used to perform verification activities are identified

and their procurement and utilisation planned. The extent to which the tools
are themselves subjected to formal verification depends upon their role.
4.3 Verification execution and reporting
The verification process activities are incrementally performed at different
product decomposition levels and in different stages, applying a coherent

bottom-up strategy and utilizing a suitable combination of different verification

methods.

In particular the verification by test is carried-out on different physical models

in agreement with the selected model philosophy.
4.4 Verification control and closeout

The verification process is monitored in its execution by the Verification Control

Board (see 5.4.2) and confirmed completed when, based on objective evidence,
the VCD deems the product as verified against the identified requirements and
the associated verification objectives. This has to be finally confirmed by the
customer.

meets the specified customer requirements and is capable of sustaining
its operational role through:
1. Verification planning;
2. Verification execution and reporting;
3. Verification control and close-out.
5.2 Verification planning
5.2.1 Verification approach
a. The supplier shall identify any constraints on the verification process
arising from both the verification objectives and the requirements
defined by the customer as needing verification.
NOTE For example, ground segment characteristics,
launch service, envisaged end to end tests
involving several suppliers. The usual general
objectives are listed in clause 4.1.1 “Verification
objectives”.
b. The requirements specified in 5.2.1a shall always include those of the
technical specification.
c. The supplier shall define the verification approach by conducting the
following steps:
1. Identify and agree with the customer the set of requirements to be
subject of the verification process.
2. Select the methods and the levels of verification, the associated
model philosophy and the verification tools.
3. Identify the stages and events in which the verification is
implemented.

d. The verification approach shall be defined by the supplier in the
Verification Plan (VP) for approval by the customer prior to
implementation.
e. For each requirement to be verified, the verification strategy shall be
defined in terms of the combination of the selected verification methods
for the different verification levels at the applicable verification stages, in
the initial issue of the Verification Control Document (VCD) also called
verification matrix (see Annex B), for approval by the customer.
5.2.2 Verification methods
5.2.2.1 General
a. Verification shall be accomplished by one or more of the following
verification methods:
1. test (including demonstration);
2. analysis (including similarity);
3. review-of-design;
4. inspection.
b. <>
c. <>
d. For each requirement verified only by analysis or review-of-design, a risk
assessment (part of the VP) shall be conducted to determine the level
(major/minor) of the impact of this requirement on the mission.
e. For each case where the risk assessment performed as a result of 5.2.2.1d
identifies the impact of the requirement as being major, risk mitigation
planning shall be defined and reported as part of the Verification Plan.
5.2.2.2 Test
a. Verification by test shall consist of measuring product performance and
functions under representative simulated environments.
b. <>
c. <>
d. <>
e. <>
f. <>
g. <>
5.2.2.3 Analysis
a. Verification by analysis shall consist of performing theoretical or
empirical evaluation using techniques agreed with the Customer.

EN 16603-10-02:2018 (E)
NOTE Techniques comprise systematic, statistical and
qualitative design analysis, modelling and
computational simulation.
b. <>
c. Analysis to demonstrate qualification of a product by similarity with an
already qualified product shall fulfil the following criteria:
1. The already qualified product was not qualified by similarity.
2. The product to be verified belongs to category A or to category B
(defined in Table 5-1) but no testing is required to achieve
qualification.
NOTE Implicitly the product to be verified cannot
belong to categories C and D equipment
(defined in Table 5-1).
d. Similarity analysis shall define differences that can dictate additional
verification activities.
e. An analysis programme shall be defined in the Verification Plan (VP).
f. An analysis programme shall be applicable to qualification and in-orbit
stages only.
5.2.2.4 Review-of-design (ROD)
a. Verification by Review-of design (ROD) shall consist of using approved
records or evidence that unambiguously show that the requirement is
met.
NOTE Examples of such approved records are design
documents and reports, technical descriptions,
and engineering drawings.
b. A review-of-design programme shall be defined in the Verification Plan
(VP).
c. A review-of-design programme shall only be applicable in the
qualification stage or in the in-orbit stage.
5.2.2.5 Inspection
a. Verification by inspection shall consist of visual determination of
physical characteristics.
NOTE Physical characteristics include constructional
features, hardware conformance to document
drawing or workmanship requirements,
physical conditions, software source code
conformance with coding standards.
b. An inspection programme shall be defined in the Verification Plan (VP).
