Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
This ISO document is copyright-protected. While the reproduction by participants in the ISO standards
development process is permitted without prior permission from ISO, neither this document nor any extract

ISO 10794 was prepared by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcommittee
SC 14, Space systems and operations.
Introduction
This International Standard is intended for application by the management in space programmes and
applications.
The formation of this International Standard takes into account the existing International Standard prepared by
ISO/TC 176, notably ISO 9000, ISO 9001 and ISO 9004, and the content of ISO 14300-1 and ISO 14300-2.
The purpose of this International Standard is to define the requirements and statements applicable to
materials, mechanical parts and processes to satisfy the mission performance requirements.
This International Standard also defines 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.

5.2 Management and consolidation of the activities
5.2.1 Relationship
The relationship between materials and processes activities and programme phases is shown in Annex A.
5.2.2 Establishing and processing of lists
5.2.2.1 Each supplier and sub-tier supplier shall establish, collect, review and deliver the declared
materials, mechanical parts and processes lists including all the items intended for use in the flight equipment.
The lists shall reflect the current design at the time of issue. These lists shall contain the materials,
mechanical parts and processes used in the current design. The objectives are as follows:
⎯ compliance with all requirements of the programme;
⎯ verification of the results of equipment supplier activities;
⎯ control and monitoring the status of materials, mechanical parts and processes in accordance with
programme milestones. For additional information, see informative Annex A.
5.2.2.2 The following constraints should be taken into account:
⎯ requirements originating from the functional specifications;
⎯ requirements and conditions specific to the project;
⎯ maximum use of the materials and processes described in approved data sources, e.g. national agency
standards, and items already approved on similar projects;
⎯ use of project related preferred lists, if available.
5.2.2.3 An analysis of the criticality of these preliminary lists shall, after checking the conformity of the
materials, mechanical parts and processes against all the project requirements, allow them to be classified
into three categories:
⎯ critical items, subject to evaluation, validation, qualification, or verification programmes, for which a
request for approval should be drafted according to the method and the formats defined in the RFA DRD.
For additional information, see informative Annex E;
⎯ items that are not critical but which do not conform to one or more project requirements (a justified
deviation request should be drafted for this category);
⎯ non-critical items.
5.2.3 Management of the lists
The supplier shall document all the MMPP used in the project in accordance with the DRD. The MMPP lists
shall be provided in a form that is exchangeable, searchable, sortable and suitable for storage and retrieval (in
accordance with the contractual requirements).
The customer shall process the lists for suppliers as necessary to achieve the objectives of exchangeability,
searchability, sortability, storability and retrievability for that set of lists, before releasing it for use by the
higher-level customer.
These lists shall be updated during the course of the project. The preliminary lists shall include the items from
suppliers' preliminary requirements and are used to identify those that are critical (available for the PDR).
The as-designed lists shall include the items from the baseline's various design files (available for the CDR).
Any change after CDR or QR shall be reflected in the list and shall be in accordance with Figure 2.
The materials, mechanical parts and processes manager is responsible within the programme to ensure that
all the information required is given and that the approval status is consistent with technical and scheduling
objectives and that the data are exchangeable.
Where no project requirements exist for a separate DMPL, the mechanical parts can be entered into a
separate section of the DML.
The materials of, for example, bearings, heatermats, and gears 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.
5.2.4 Supplier role and responsibilities
5.2.4.1 The supplier shall be responsible for the following tasks:
⎯ obtaining the correct and complete lists from lower-level suppliers;
⎯ providing provisional and, later, definitive approval for each list;
⎯ submitting the project declared lists for approval prior to initiation of the hardware phase (before critical
design review).
8 © ISO 2011 – All rights reserved

The lists established by the suppliers shall include all the information described in this International Standard.
Amendments to the lists shall be implemented only through established change procedures.
5.2.4.2 Any of the following documentation shall be made available to the final customer upon request:
⎯ RFA (reference and issue);
⎯ material, mechanical parts or processes justification files;
⎯ evaluation reports;
⎯ deviation requests.
5.3 Technical constraints
Parts and materials shall satisfy the mission's functional constraints. They shall also satisfy both ground
environment constraints (e.g. manufacture, tests, storage, maintenance, transport and integration) and flight
constraints (launch and orbit). The technical criteria from 6.1 shall be taken into account, according to the
mission.
The estimated availability of the parts and products obtained from materials and processes used shall be
compatible with the final system's life cycle (tests, storage and mission).
5.4 Cleanliness and contamination control
The supplier shall establish and maintain an effective contamination and cleanliness control programme
including, as a minimum, the following:
⎯ cleaning procedures; and
⎯ cleanliness monitoring procedures or methods.
The risks of chemical or particle pollution generated by parts, materials or processes used shall be identified
and reduced in accordance with mission requirements (cleanliness or contamination analysis).
For cleanliness- or contamination-critical applications, a specific cleanliness control plan and requirement
specification (chemical and particle) shall be established.
5.5 Safety hazardous parts and materials
Parts and materials with hazardous characteristics shall be identified, managed and processed according to
customer standards.
5.6 Optical, mechanical or electrical GSE hardware
When optical, mechanical or electrical GSE materials are used in thermal vacuum or interfacing with flight
hardware, possible degradation shall be taken into account (e.g. contamination, surface degradation,
flammability, electromechanical and chemical effects).
6 Material control
6.1 Technical criteria for selection of materials
The following requirements shall be taken into account only if the environmental conditions of the mission
require their application. The agency- or customer-specific requirements, test methods and accept or reject
criteria shall be applied.
a) Temperature: Material properties shall be compatible with the thermal environment to which they are
exposed.
b) Thermal cycling: Materials subject to thermal cycling shall be assessed for their ability to withstand
induced thermal stress and shall be tested according to approved procedures.
c) Vacuum:
⎯ Materials selection shall be made in accordance with approved data sources.
⎯ Outgassing tests shall be carried out according to approved procedures.
d) Offgassing, toxicity, bacterial and fungus growth: Spacecraft and associated equipment shall be
manufactured from materials and by processes that shall not cause an unacceptable hazard to personnel
or hardware, whether on the ground or in space.
e) Flammability: The materials flammability resistance shall be evaluated for the most hazardous
environment envisaged for their use.
f) Radiation: Materials used on the spacecraft external surfaces shall be assessed to determine their
resistance to the radiation dosage expected during the mission.
The genealogy of fluorine resin (PTFE) has weak resistance to the radiation dosage. Therefore, if the
material is used inside the spacecraft, it shall be assessed in terms of the resistance to the radiation
dosage.
g) Electrical charge and discharge: External surfaces of the spacecraft shall be sufficiently conductive,
interconnected and grounded to the spacecraft structure to avoid the build-up of differential charges.
h) Lightning strike: Provision shall be made in the design to ensure that the safety and functionality of the
vehicle are not compromised by the occurrence of a lightning strike during launch or return.
i) Corrosion: For all materials that come into contact with atmospheric gases, cleaning fluids or other
chemicals, it shall be demonstrated that the degradation of properties during their anticipated service life
is acceptable in terms of the performance and integrity requirements.
j) Stress corrosion:
⎯ Materials used for structural and load-bearing applications (subject to tensile stress) shall be chosen
in conformance with approved data sources.
⎯ Any material not covered by an approved standard shall be tested according to approved procedures.
k) Fluid compatibility:
⎯ Materials within the system exposed to liquid oxygen (LOX), gaseous oxygen (GOX) or other reactive
fluids, both directly and as a result of single-point failures, shall be compatible with that fluid in their
application.
10 © ISO 2011 – All rights reserved

⎯ The possibility of hydrogen embrittlement occurring during component manufacture or use shall be
assessed. An appropriate material evaluation shall be undertaken, including the assessment of
adequate protection and control.
l) Galvanic compatibility: When bimetallic contacts are used, the choice of the pair of metallic materials
used shall be taken into account. This also includes metal-to-conductive fibre-reinforced materials
contacts.
m) Atomic oxygen:
⎯ All materials considered for use on the external surfaces of spacecraft intended for use in low earth
orbit (LEO) altitudes (between 200 km and 700 km) shall be evaluated for their resistance to atomic
oxygen (ATOX).
⎯ Test procedures shall be subject to the approval of the customer.
n) Micrometeoroids and debris: The effect of impacts by micrometeoroids and debris on materials shall be
reviewed and assessed on a case-by-case basis and their use shall comply with safety evaluation and
assessment results concerning design and application criteria or details.
o) Moisture absorption and desorption: Precautions shall be taken to avoid moisture absorption during
manufacture and storage of CFRP-type materials.
p) Mechanical contact surface effects (cold welding, fretting, wear): For all solid surfaces in moving contact
with other solid surfaces, it shall be demonstrated that the degradation of surface properties over the
complete mission is acceptable from a performance point of view.
q) Life: materials shall be selected to ensure sufficient life with respect to the intended application.
r) Magnetic material: The use of the magnetic material should be kept to a minimum in consideration of
system requirements.
6.2 Selection
6.2.1 Materials shall be chosen giving preference to the following:
⎯ those successfully used for an identical application in other space programmes that are similar with
respect to environment constraints and lifetime to the proposed application;
⎯ those for which satisfactory evaluation results have been obtained on samples representative of the
application with a sufficient margin as regards conditions of use;
⎯ those included in approved data sources, for example ESA and NASA data banks.
6.2.2 Whether the materials are already validated or remain to be validated, their selection shall take into
account the following criteria:
⎯ continuity of supply;
⎯ reproducibility of characteristics;
⎯ approved supplier/distributor.
6.3 Declared materials list content
The declared materials list (DML) shall be broken down into clear categories to facilitate locating each item in
the documentation (an example of such a breakdown is given in the DML DRD). For additional information,
see informative Annex B. The DML shall include the following information:
⎯ issue status of DML;
⎯ unique item number (as the reference of the material in the DML) that shall be the same throughout the
duration of the project;
⎯ material designation (commercial identification);
⎯ material keys, e.g. AISI; AA; CDA, UNS, ASTM;
⎯ chemical nature and type of product;
⎯ manufacturer's name and procurement specifications or standards;
⎯ summary of processing parameters (e.g. finish, temper condition, mix ratio and curing);
⎯ use and location;
⎯ applicable process identifier from the DPL;
⎯ environmental code;
⎯ size code, test data (e.g. outgassing, stress corrosion cracking, corrosion and test data references);
⎯ approval status (with reference to the approval authority, to test report and similar previous applications).
Any coding or acronyms used within the list shall be defined within the document. An example of a suitable
completed DML format is given in Table B.4 in the DML DRD. For additional information, see informative
Annex B.
6.4 Criticality analysis
The objective of the analysis is to identify whether further data are required to conform to mission
requirements.
a) The supplier shall analyse all the materials contained in his or her preliminary lists with respect to
criticality and in correlation with the risk analysis performed.
b) Any material not meeting the project requirements shall be the subject of an RFA that is submitted to the
next customer.
c) The RFA shall include the reason and details of the subsequent evaluation and validation that it is
necessary to perform. For additional information, see informative Annex E and 5.2.2.
d) Any material when specifically required; marking inks can be excluded.

6.5 Evaluation and validation phases
6.5.1 General
Depending on the results of the criticality analysis, the supplier shall perform either evaluation and
qualification phases, or a qualification phase only for all critical parts. The choice between these two
approaches takes into account
⎯ knowledge of the part (e.g. new part, new use or change of configuration); and
⎯ extension of the application.
Procurement and validation results, together with associated documents, shall be available for review at the
contractor's premises before the start of evaluation or qualification phases.
6.5.2 Evaluation phase
The evaluation shall consider the following as a minimum for each material with unknown characteristics:
⎯ the limits of use;
⎯ the material's physical, chemical or functional characteristics along with their values and tolerances;
⎯ behavioural tendencies and degradation processes depending on environmental parameters (including
sensitivity to pollution);
⎯ acceptance criteria.
When evaluation is performed, an evaluation programme (available at PDR, in accordance with Figures 1 and
2) shall be drawn up, implemented and an evaluation report (available before CDR, in accordance with
Figures 1 and 2 and Table 1) shall be drawn up.
6.5.3 Validation phase
For all materials with unknown characteristics, a validation programme (available at PDR) shall be drawn up
by the supplier and then implemented to check or confirm that the materials satisfy the mission requirements
with appropriate margins as necessary to obtain validation status.
Validation status shall depend on the results obtained (validation report) and the review of corresponding
documentation (available at CDR).
6.5.4 Approval phase
Provided that the requirements in 6.5.2 and 6.5.3 are satisfied, the material then receives an approval
identification in the declared materials list for the project.
If approval is not granted, the supplier in charge of the item shall either
⎯ select another material;
⎯ propose a modified evaluation programme and resubmit for approval; or
⎯ initiate a deviation procedure if the above actions fail to achieve positive results.
6.5.5 Deviation request
All materials not conforming to project requirements, whether at the end of criticality analysis or of evaluation
and validation tests, shall form the subject of a duly justified deviation request in accordance with ISO 27025.
6.6 Procurement of materials
6.6.1 Procurement specifications
All materials shall be procured to an internationally or nationally recognized specification or an in-house fully
configured procurement specification that defines the material's properties, the materi
