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 documents 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).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www .iso

This document was prepared by Technical Committee ISO/TC 20, Aircraft and space vehicles,
Subcommittee SC 14, Space systems and operations.
This edition cancels and replaces the first edition (ISO 14621-2:2003), which has been technically
revised. The main changes compared to the previous edition are as follows:
— Introduction and definitions have been revised,
— consistency has been checked with ISO 14621-1, and
— the document has been aligned with the ISO/IEC Directives Part 2, 2018 edition.

Introduction
ISO 14621-1 and ISO 14621-2 are designed to jointly assist the user and supplier communities in
developing and executing an effective process for the design, selection and application of electrical,
electronic, and electromechanical (EEE) space parts throughout the life cycle of the programme.
NOTE In both ISO 14621-1 and ISO 14621-2, the family of EEE parts includes electro-optical parts.
The strategy represented in the ISO 14621 series is:
— for ISO 14621-1 a system approach to managing risk throughout the life cycle of the programme, by
developing, selecting and properly applying the right EEE part for its intended application;
— for ISO 14621-2 a framework for developing and documenting an EEE parts control programme
to assure that the parts used in space flight hardware have acceptable risk, i.e. possess adequate
functional, radiation and reliability characteristics to meet the system requirements.
Both ISO 14621-1 and ISO 14621-2 should be tailored to meet the specific needs of each individual
programme, i.e. to address the applicable system performance requirements, risk tolerance, budget,
mission duration, operating environment, and schedule. Tailoring should result in a set of planned
activities that are not only capable of achieving all contractual EEE parts related requirements, but
also commensurate with the space system’s unit-value/mission-criticality and life cycle technical data
product requirements.
NOTE This type of planning is sometimes referred to as capability-based Safety, Dependability, and Quality
Assurance (SD&QA) programme tailoring; and the guidance for performing it is provided in ISO/TS 18667.
ISO 14621-1 and ISO 14621-2 are relevant to all users and customers of space systems, and the suppliers
and vendors that furnish space flight hardware. However, to utilize these documents to their fullest
potential, it is necessary to understand the commercial space business environment which has unique
cost and schedule constraint challenges.

Space systems — Electrical, electronic and
electromechanical (EEE) parts —
Part 2:
Control programme requirements
1 Scope
This document establishes technical guidelines for developing and documenting an electrical, electronic
and electromechanical (EEE) parts control program, in order to assure that the parts used in the flight
hardware are acceptable and possess adequate functional, radiation and reliability characteristics to
meet the system requirements. The family of EEE parts includes electro-optical parts.
This document identifies a set of management guidelines for dealing with space systems engineering
activities and defines the minimum existing processes on the subject.
These guidelines are tailorable to the needs of each individual programme based on the project
performance criteria, risk tolerance, budget, mission duration, environment, schedule and other
considerations. This document is applicable to all customers and suppliers furnishing flight hardware
and is suitable for re
