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 lower-level 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; and
— control and monitoring the status of materials, mechanical parts and processes in conformance
with programme milestones. For additional information, see informative Annex A.
5.2.2.2 The following constraints should be assessed:
— 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; and
— use of project related preferred lists, if available.
5.2.2.3 An analysis of the criticality of these preliminary lists shall be performed as such that, 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;
— items that are not critical but which do not conform to one or more project requirements; and
— non-critical items.
For items classified as critical, a request for approval shall be submitted in conformance with
Annex E. For items classified as not critical but which are not in conformance with one or more project
requirements, a justified deviation request should be drafted.
5.2.3 Management of the lists
The supplier shall document all materials in the Declared materials list in conformance with Annex B.
The supplier shall document all mechanical parts in the Declared mechanical parts list in conformance
with Annex C.
The supplier shall document all processes in the Declared process list in conformance with Annex D.
The supplier shall process the lists of lower-level suppliers to ensure exchangeability, traceability,
searchability, sortability, storability and retrievability for that set of lists, before submitting it to the
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 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 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, screw 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.
The supplier shall establish, collect, review and deliver the declared materials, mechanical parts and
processes lists in an electronic format in conformance with Annex B, Annex C, and Annex D.
The supplier shall demonstrate that the lists have been formally approved prior to their delivery to the
customer.
8 © ISO 2018 – All rights reserved
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; and
— submitting the project declared lists for approval prior to initiation of the hardware phase,
before CDR.
The lists specified in the requirement by the suppliers shall include all the information described in this
document. Amendments to the lists shall be implemented through established change procedures.
5.2.4.2 The following documentation shall be delivered to the customer upon request:
— RFA with reference and issue in conformance with DRD in Annex E;
— evaluation reports; and
— deviation requests.
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.
5.3 Technical constraints
Mechanical parts, materials and processes shall satisfy the mission's functional requirements and
constraints. Mechanical parts, materials and processes shall satisfy both ground environment
constraints (e.g. manufacture, tests, storage, maintenance, transport and integration) as well as flight
requirements and flight constraints (launch and orbit).
The estimated availability of the parts and products obtained from materials and processes used shall
be compatible with the space system's life cycle (tests, storage and mission).
5.4 Cleanliness and contamination control
The supplier shall establish and maintain a contamination and cleanliness control programme
including, as a minimum:
— 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 chemical and particle requirement
specification and a specific cleanliness control plan shall be established.
5.5 Safety hazardous parts and materials
Mechanical 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 assessed (e.g. contamination, surface degradation,
flammability, electromechanical and chemical effects).
6 Material control
6.1 Technical criteria for selection of materials
Material design data shall be generated for the intended service conditions using test and analysis
procedures approved by the customer. Material properties shall be compatible with the environments
to which they are exposed during terrestrial testing prior to launch, and during the mission.
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
acceptance or rejection criteria shall be applied.
a) Temperature: Material properties shall be compatible with the thermal environment to which they
are exposed. Examples of thermal environment are also the passage through transitions, ductile-
brittle temperatures, e.g. phase transitions, ductile-brittle transition temperatures for metals, glass
transition (Tg) for polymer materials, and environmental factors which affect these properties,
such as moisture.
b) Thermal cycling and thermo optical: Materials subject to thermal cycling shall be assessed for their
ability to withstand induced thermal stress and shall be tested according to approved procedures.
Thermo optical properties shall be evaluated in conformance technical requirements. Directional
effects due to manufacturing or processing shall be evaluated via dedicated testing to be agreed
with customer.
c) Vacuum:
— Outgassing screening tests shall be carried out according to approved procedures. The screening
process applied depends on the application.
— All organic materials for use in space systems shall be evaluated to determine their outgassing
characteristics.
— The need for retest outgassing characteristics of materials used for an extended period of time
at a temperature higher than 50 °C should be mutually agreed with the customer.
d) Offgassing, toxicity: Spacecraft and associated equipment shall be manufactured from materials
and by processes that do not cause an unacceptable hazard to personnel or hardware, whether on
the ground or in space. For materials for the use in manned compartments of a spacecraft or space
segment elements, offgassing and toxicity analysis shall be performed. The levels of offgassing and
toxicity shall be agreed with customer.
e) Flammability: The materials flammability resistance shall be evaluated for the most hazardous
environment envisaged for their use, and be applicable to:
— unmanned spacecraft or space segment elements launched by a manned space transportation
system when powered on launch; and
— manned spacecraft and space segment elements.
f) Radiation:
— Materials exposed to radiation shall be assessed to determine their resistance to the radiation
dosage expected during the mission.
10 © ISO 2018 – All rights reserved
— Evaluation of materials resistance to radiation shall include the combined effects of particle
radiation and ultraviolet radiation in the normal space environment, along with any mission-
specific radiation levels.
— The effect of bleaching due to vacuum or air recovery shall be evaluated, in case ex-situ
measurements are performed.
— In case synergistic testing is not possible it shall be proven that synergistic effects caused by
radiation and temperature are not degrading the materials' properties.
— In case technical limits prevent the synergistic testing approach, it shall be so justified, and the
justification for sequential testing shall be provided.
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) 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. All mechanical
parts, assemblies and equipment, including spares, shall be finished to provide protection from
corrosion.
i) Stress corrosion:
— Materials used for structural and load-bearing applications (subject to tensile stress) shall be
selected in conformance with approved data sources.
— Any material not covered by an approved standard shall be tested according to approved
procedures.
j) Fluid compatibility:
— Materials within the system exposed to reactive fluids, both directly and as a result of single
point failures when failure propagation effects cause hazardous operation of interfacing
hardware shall be compatible with that fluid in their application. Examples of reactive fluids
are liquid oxygen (LOX) and gaseous oxygen (GOX).
— The compatibility of materials which are or can come into contact with LOX or GOX shall be
evaluated except the case specified in the requirement.
— In case no compatibility data are available, tests shall be performed for reactive fluids other
than oxygen.
k) Galvanic compatibility: When bimetallic contacts are used, the choice of the pair of metallic
materials used shall be agreed with the customer. This also includes metal-to-conductive fibre-
reinforced materials contacts. Galvanic compatibilities shall be selected in conformance with
Table 2. Materials not listed in Table 2 shall be evaluated in a flight-simulated configuration using
an accelerated environment to be agreed by the customer.
l) Atomic oxygen:
— All materials for use on the external surfaces of spacecraft for use in low earth orbit (LEO)
altitudes, between 200 km and 700 km, shall be evaluated for their resistance to atomic oxygen
(ATOX). The flux level varies with altitude, velocity vector and solar activity. Fluence levels vary
with the duration of exposure.
— Test procedures shall be subject to the approval of the customer.
The effect of ATOX on thermo optical properties including specularity shall be evaluated.
