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.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types of
ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent rights
in respect thereof. As of the date of publication of this document, ISO had not received notice of (a) patent(s)
which may be required to implement this document. However, implementers are cautioned that this may not
represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not

Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcommittee
SC 14, Space systems and operations.
This second edition cancels and replaces the first edition (ISO 20188:2018), which has been technically
revised.
The main changes are as follows:
— — normative references with related references in the text have been updated;
— — requirement related to the role of product assurance manager has been added;
— — requirements have been updated in 6.216.21 (non-conformity control), in 6.256.25 (quality assurance
role in configuration management, in Clause 7Clause 7 (dependability) and in Clause 8Clause 8 (safety);
— — the Bibliography has been updated.

Introduction
This document specifies the product assurance (PA) activities from the standpoint of commercial business
during each phase of the project such as design, procurement, manufacturing, assembly, integration, test, and
launch. These product assurance requirements are requested by customers for accomplishing the mission
successfully and can lead to customer satisfaction.
The responsibility of the prime contractor is to allocate these requirements to subcontractors and suppliers,
and to ensure their implementation.
The prime objective of PA is to ensure that commercial satellites accomplish their defined mission objectives
and that they are safe and reliable.
A further objective is to achieve more cost-effective space projects and thereby to promote competitiveness
by coordinating the development and implementation of appropriate PA methods and standards.
PA requirements defined in this document have been established to prevent potential problems. PA
programmes also ensure that hardware and software of ground support equipment are also safe, reliable and
do not degrade the flight hardware in any way.
This document intends to clarify the best practices and typical requirements dealing with product assurance
activities in commercial business, and realize quality improvement especially for customers having less
experience.
The requirements described in this document are created by comparing and mixing experience and practical
management methodologies used by main actors of aerospace industry in the world. The framework of PA
