FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
The main task of IEC technical committees is to prepare International Standards. However, a
technical committee may propose the publication of a technical report when it has collected
data of a different kind from that which is normally published as an International Standard, for
example "state of the art".
IEC TR 62396-7, which is a technical report, has been prepared by IEC technical committee
107: Process management for avionics.

PROCESS MANAGEMENT FOR AVIONICS –
ATMOSPHERIC RADIATION EFFECTS –

Part 7: Management of single event effects (SEE)
analysis process in avionics design

1 Scope
This part of IEC 62396, which is a technical report, describes a process to account for the
effects of atmospheric radiation on electronic equipment. Single event effects (SEE) due to
atmospheric radiation are one class of possible failure mechanisms that are addressed in the
safety and reliability analyses of electronic equipment and associated functions.
This document focuses on electronic components, electronic equipment and associated
electronic functions. System level analysis is not addressed in this document.
This document is intended to describe an approach to accounting for SEE in electronic
equipment design, design review, and it can provide aid in the aerospace certification
process. This document establishes an example process for assessing electronic components
in the atmospheric radiation environment, evaluating for mitigations/protections/utilizations,
and addressing the electronic equipment impacts of the SEE. The process is intended to
support an SEE analysis for electronic equipment.
It does not describe, in detail, methods used to mitigate the effects of SEE in the electronic
equipment design.
NOTE 1 IEC 62396-3 provides further details for this process.
NOTE 2 IEC 62396-2 provides further details for SEE testing.
This document, by itself, is not a program requirements document, i.e. it does not contain the
word “shall.” However it describes a process that can be used, for example, at the discretion
and agreement of the users, to aid in the preparation and the maintenance of an electronic
components management plan (see [1] and [7]). The output of the process described in this
document provides data as an input into the product safety and reliability analyses.
Although developed for the avionics industry, this document can be used by other industrial
sectors at their discretion.
