European foreword
This document (EN 16602-70:2016) has been prepared by Technical Committee CEN-CENELEC/TC 5
“Space”, the secretariat of which is held by DIN.
This European Standard (EN 16602-70:2016) originates from ECSS-Q-ST-70C 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 2017, and conflicting national standards shall be
withdrawn at the latest by April 2017.
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 13291-3:2003.
The main changes with respect to EN 13291-3:2003 are listed below:
- new EN number and modified title,
- Reorganization of the content of the document to separate descriptive text and requirements,
including clarification, modification of requirements and implementation of change requests,
- Alignment of the three Standards EN 16603-32-08 (based on ECSS-E-ST-32-08C Rev.1),
EN 16602-70 (based on ECSS-Q-ST-70C Rev.1) and EN 16602-70-71 (based on ECSS-Q-ST-70-
71C),
- Additon of Subclauses 5.1.18 "Bacterial and fungus growth", 5.1.19 "Hydrogen embrittlement"
and 5.1.20 "Manned environment" coming from ECSS-Q-ST-70-71A Rev.1.
This document has been prepared under a mandate 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, Slovakia, Slovenia, Spain,
Sweden, Switzerland, Turkey and the United Kingdom.
Scope
This European Standard specifies the requirements and statements applicable
to materials, mechanical parts and processes to satisfy the mission performance
requirements.
This standard also specifies the documentation requirements and the
procedures relevant to obtaining approval for the use of materials, mechanical
parts and processes in the fabrication of space systems and associated
equipment.
This standard covers the following:
• management, including organization, reviews, acceptance status and
documentation control;
• selection criteria and rules;
• evaluation, validation and qualification, or verification testing;
• procurement and receiving inspection;
• utilization criteria and rules.
The relationship between activities and programme phases is defined in Annex E.
The provisions of this standard apply to all actors involved at all levels in the
production of space systems. These can include manned and unmanned
spacecraft, launchers, satellites, payloads, experiments, electrical ground
support equipment, mechanical ground support equipment, and their
corresponding organizations.
This standard may be tailored for the specific characteristics and constraints of a
space project in conformance with ECSS-S-ST-00.

3.4 Nomenclature
The following nomenclature applies throughout this document:
a. The word “shall” is used in this standard to express requirements. All the
requirements are expressed with the word “shall”.
b. The word “should” is used in this standard to express recommendations.
All the recommendations are expressed with the word “should”.
NOTE It is expected that, during tailoring,
recommendations in this document are either
converted into requirements or tailored out.
c. The words “may” and “need not” are used in this standard to express
positive and negative permissions, respectively. All the positive
permissions are expressed with the word “may”. All the negative
permissions are expressed with the words “need not”.
d. The word “can” is used in this standard to express capabilities or
possibilities, and therefore, if not accompanied by one of the previous
words, it implies descriptive text.
NOTE In ECSS “may” and “can” have completely
different meanings: “may” is normative
(permission), and “can” is descriptive.
e. The present and past tenses are used in this standard to express
statements of fact, and therefore they imply descriptive text.

conformance with Annex A.
b. The supplier shall document all mechanical parts in the Declared
mechanical parts list in conformance with Annex B.
c. The supplier shall document all processes in the Declared process list in
conformance with Annex C.
d. The supplier shall process the lists of lower level suppliers to ensure
exchangeabililty, traceability searchability, sortability, storability and
retrievability for that set of lists, before submitting it to the customer.
e. The lists specified in the requirement 4.2.3a, 4.2.3b and 4.2.3c shall be
updated during the course of the project.
f. The preliminary lists specified in the requirement 4.2.3a, 4.2.3b and 4.2.3c
shall include the items from suppliers’ preliminary needs.
NOTE They are used to identify critical items
(available for the PDR).
g. The as-designed lists shall include the items from the baselines various
design files, available for CDR.
h. Any change after CDR or QR shall be reflected in the list and shall be in
accordance with Figure 4-1 (Part 2).
NOTE 1 The MMPP manager is responsible within the
programme to ensure that all the information
needed is given and that the approval status is
consistent with technical and scheduling
objectives and data is exchangeable.
NOTE 2 Where no project requirements exist for a
separate DMPL, the mechanical parts can be
entered into a separate section of the DML.
NOTE 3 The materials of, for example, screws and nuts
that are made up of a few materials can be
listed in the DMPL. The materials (metals and
plastics) of complex parts can be listed in the
DML with, for example, outgassing, toxicity,
flammability, corrosion and stress corrosion
values and reference to the DMPL item.
i. The supplier shall establish, collect, review and deliver the declared
materials, mechanical parts and processes lists in an electronic format in
conformance with Annex A, Annex B, and Annex C.
j. The supplier shall demonstrate that the lists specified in the requirements
4.2.3a, 4.2.3b and 4.2.3c have been formally approved prior to their
delivery to the customer.
4.2.4 Supplier role and responsibilities
a. The supplier shall perform the following tasks:
1. obtaining the correct and complete lists from lower level suppliers;
2. providing provisional and, later, definitive approval for each list;
3. submitting the project declared lists for approval prior to initiation
of the hardware phase, before CDR.
b. The lists specified in the requirement 4.2.3i by the suppliers shall include
all the information described in this standard.
c. Amendments to the lists specified in the requirement 4.2.3 a, b and c shall
be implemented through established change procedures.
d. The following documentation shall be delivered to the customer upon
request:
1. RFA with reference and issue in conformance with DRD in Annex D;
2. evaluation reports;
3. deviation requests.
e. The material, mechanical parts or process justification files shall be made
available to the customer upon request either on the supplier site, or by
any other process agreed by both parties.
NOTE For example, by non-disclosure agreement.
4.3 Technical constraints
a. Mechanical parts, and materials and processes shall satisfy the mission’s
functional requirements and constraints.
b. Mechanical parts, and materials and processes shall satisfy both ground
environment and flight requirements and constraints.
NOTE Examples are:
• Ground environment constraints:
manufacture, tests, storage, maintenance,
transport and integration
• Flight constraints: launch and orbit.
c. << deleted >>
d. The estimated availability of the parts and products obtained from
materials and processes used shall be compatible with the space system’s
life cycle.
NOTE Examples of space system’s life cycle are tests,
storage and mission.
4.4 Cleanliness and contamination control
a. The supplier shall establish and maintain a contamination and cleanliness
control programme including, as a minimum:
1. cleaning procedures, and
2. cleanliness monitoring procedures or methods.
b. The risks of chemical or particle pollution generated by parts, materials
or processes used shall be identified and reduced as specified in ECSS-M-
ST-80, 7.2, in conformance with mission requirements.
NOTE Cleanliness or contamination analysis is
example of mission requirem
