FOREWORD

1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.

3) The documents produced have the form of recommendations for international use and are published in the form

of standards, technical reports or guides and they are accepted by the National Committees in that sense.

4) In order to promote international unification, IEC National Committees undertake to apply IEC International

Standards transparently to the maximum extent possible in their national and regional standards. Any

divergence between the IEC Standard and the corresponding national or regional standard shall be clearly

indicated in the latter.

5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any

equipment declared to be in conformity with one of its standards.

6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject

of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 61000-4-24 has been prepared by subcommittee 77C: Immunity to

high-altitude nuclear electromagnetic pulse (HEMP), of IEC technical committee 77: Electro-

magnetic compatibility.

It forms section 24 of part 4 of IEC 61000. It has the status of a basic EMC publication in

accordance with IEC Guide 107.
The text of this standard is based on the following documents:
FDIS Report on voting
77C/37/FDIS 77C/40/RVD

Full information on the voting for the approval of this standard can be found in the report on

voting indicated in the above table.

INTRODUCTION

The IEC has initiated the preparation of standardized methods to protect civilian society from

the effects of high-altitude nuclear bursts. Such effects could disrupt systems for

communications, electric power, information technology, etc.

This section of IEC 61000-4 is part of a complete set of standards that covers the entire

category of immunity to high-altitude nuclear electromagnetic pulse. The appropriate acronym

is either HA-NEMP or more simply HEMP.

The application of this standard is, however, not dependent on access to other sections and

parts of the IEC 1000 and IEC 61000, except for those specifically referred to.
Attention is drawn to IEC 1000-5-5.

Basic EMC publication
1 Scope

This section of IEC 61000-4 deals with methods for testing protective devices for HEMP

conducted disturbance. It primarily covers testing of voltage breakdown and voltage-limiting

characteristics but also methods to measure the residual voltage under HEMP conditions for

the case of very fast changes of voltage (u) and current (i) as a function of time.

2 Normative references

The following normative document contains provisions which, through reference in this text,

constitute provisions of this section of IEC 61000-4. At the time of publication, the edition

indicated was valid. All normative documents are subject to revision, and parties to agreements

3 Definitions

For the purposes of this section of IEC 61000-4, the following definitions apply:

3.1 DUT: Device under test

3.2 gas discharge tube: A gap, or several gaps with two or three metal electrodes

hermetically sealed so that gas mixture and pressure are under control, designed to protect

apparatus or personnel from high transient voltages.

3.3 primary protection element: First protective element seen from the unprotected side of

a protection measure, diverting the main part of the surge current.

3.4 protected side: The side of a protection measure where the equipment is situated that

has to be protected.
3.5 unprotected side: The side of a protection measur
