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.

ISO 10794:2011(E)
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.

5.1 Materials, mechanical parts and processes programme management
5.1.1 Materials, mechanical parts and processes activity diagram
The general activity within the framework of a project is summarized by the flow chart shown in Figures 1
and 2 and Table 1.
5.1.2 Product assurance plan
Suppliers shall provide a material, mechanical parts and processes plan in accordance with ISO 14300-2 and

5.1.3 Management
The supplier shall appoint a materials, mechanical parts and processes manager who ensures that the
requirements laid out in this International Standard are satisfied. This manager shall be the customer's contact
as far as application of this International Standard is concerned within the overall PA reporting system. The
manager shall periodically inform the customer of the progress of tasks relating to its application. The
manager shall ensure conformance to technical and scheduling aspects of the various actions undertaken
(status of material validation, part qualification and process verification).
The manager shall ensure that all suppliers apply the requirements of this International Standard.
5.1.4 Customer reviews
To obtain the validation status for materials and qualification status for parts and verification status for

 Processes are verified.
And in addition: Skills training schools are customer approved.
 Outside test or evaluation laboratories are customer approved.
 Operators and inspectors for critical processes are trained, certified and monitored.

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;
© ISO 2011 – All rights reserved 7

---------------------- Page: 13 ----------------------
ISO 10794:2011(E)
⎯ 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 require
