ESD测试标准 This International Standard relates to the immunity requirements and test methods for electrical and electronic equipment subjected to static electricity discharges, from operators directly, and to adjacent objects. It additionally defines ranges of test levels which relate to different environmental and installation conditions and establishes test procedures. The object of this standard is to establish a common and reproducible basis for evaluating the performance of electrical and electronic equipment when subjected to electrostatic discharges. In addition, it includes electrostatic discharges which may occur from personnel to objects near vital equipment.

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 specifications, 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 61000-4-2 has been prepared by subcommittee 77B: High-
frequency phenomena, of IEC technical committee 77: Electromagnetic compatibility.
It forms section 2 of part 4 of IEC 61000. It has the status of a basic EMC publication in
accordance with IEC Guide 107.
It is based on the IEC 60801-2 (second edition: 1991):
Electromagnetic compatibility for
industrial process measurement and control equipment – Part 2: Electrostatic discharge
requirements,
prepared by IEC technical committee 65: Industrial-process measurement and
control.
According to a recommendation of ACEC at its meeting of December 1989, the scope of this
standard has been extended to all kinds of electrical and electronic equipment. For this
purpose it has been decided to transfer the 60801 series of publications to the 61000-4
series:
EMC testing and measurement techniques
, of technical committee 77.
61000-4-2
IEC:1995+A1:1998 – 7 –
+A2:2000
No technical changes, only editorial amendments, have been made with this transfer and
reference to IEC 60801-2 (1991) or IEC 61000-4-2 is equivalent.
This consolidated version of IEC 61000-4-2 is based on the first edition (1995) [documents
77B(CO)21 and 77B/145/RVD], its amendment 1 (1998) [documents 77B/216/FDIS and
77B/226/RVD] and amendment 2 (2000) [documents 77B/291+292/FDIS and 77B/298+299/RVD].
It bears the edition number 1.2.
A vertical line in the margin shows where the base publication has been modified by
amendments 1 and 2.
Annexes A and B are for information only.
The committee has decided that the contents of the base publication and its amendments will
remain unchanged until 2003. At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.
