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
constitute an endorsement.

Part 4:
Spacecraft assembly, integration and test
1 Scope
This document provides requirements for the safety management and operation of assembly, integration
and test (AIT) activities related to spacecraft projects and applications including the responsibilities of the
organization involved in the AIT operations for spacecraft products.
This document provides a method to identify hazards, control and reduce safety risk to acceptable levels in
the activities of spacecraft assembly, integration, testing, hoisting, logistics and handling.
This document is applicable to space test centres and entities providing operating infrastructure and
facilities for spacecraft AIT. It can serve as a reference for the AIT of the spacecraft system, its subsystems
and equipment.
