Electromagnetic compatibility (EMC) - Part 2: Environment - Section 9: Description of HEMP environment - Radiated disturbance
This section of IEC 61000-2 defines the high-altitude electromagnetic pulse (HEMP) environment that is one of the consequences of a high-altitude nuclear explosion. Those dealing with this subject consider two cases: - high-altitude nuclear explosions; - low-altitude nuclear explosions. For civil systems, the most important case is the high-altitude nuclear explosion. In this case, the other effects of the nuclear explosion: blast, ground shock, thermal and nuclear ionizing radiation are not present at the ground level. However the electromagnetic pulse associated with the explosion may cause disruption of, and damage to, communication, electronic and electric power systems thereby upsetting the stability of modern society. The object of this standard is to establish a common reference for the HEMP environment in order to select realistic stresses to apply to victim equipment for evaluating their performance.

La présente section de la CEI 61000-2 définit l'environnement IEMN-HA (impulsion électromagnétique à haute altitude) consécutif à une explosion nucléaire à haute altitude. Deux cas sont généralement étudiés; - les explosions nucléaires à haute altitude; - les explosions nucléaires à basse altitude. Pour les systèmes civils, le cas le plus important est celui des explosions nucléaires à haute altitude. Dans ce cas, les autres effets de l'explosion nucléaire (souffle, onde de choc au sol, rayonnements thermiques et ionisants nucléaires) n'existent pas au niveau du sol. Les impulsions électromagnétiques liées à l'explosion peuvent cependant perturber et endommager les systèmes de communication, les systèmes électroniques et le réseau électrique, mettant par là même en péril l'équilibre de la sociéé moderne. Le but de cette norme est d'établir une référence commune sur l'environnement IEMN-HA permettant de définir des contraintes réalistes à appliquer afin d'évaluer les performances des équipements atteints.

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 cooperation 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, prepared by technical committees on which all the
National Committees having a special interest therein are represented, express, as nearly as possible, an international
consensus of
opinion on the subjects dealt with.
3) They have the form of recommendations for international use published in the form of standards, technical repo rts or
guides and they are accepted by the National Committees in that sense.
4) In order to promote international unification, IEC National
