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.

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.

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation on the meaning of ISO specific terms and expressions related to conformity

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers

to Trade (TBT) see the following URL: Foreword - Supplementary information

NOTE 1 The peak current level is taken from the measurement system without any data interpolation.

NOTE 2 The target used with this measurement system fulfils the requirements of A.1 and A.2. An example is defined in

Annex B.

NOTE 3 The measurement times (30 ns, 60 ns, 65 ns, 130 ns, 180 ns, 360 ns, 400 ns and 800 ns) are derived from the

resistance-capacitive (RC) time constant −40 % (current t ) and +20 % (current t ), to define two values on the falling slope

of the current pulse in accordance with IEC 61000–4-2.

Replace the following in Annex A (see below).
In the second sentence of A.2.3.1, replace: “Table A.1” with “Table 1”.

At the beginning of the first paragraph of A.2.3.4, add: “The measurement discharge current procedure

is shown in Table A.1”.

Replace the title of Table A.1: “Contact discharge verification procedure” with “Contact discharge current

waveform verification procedure”.

Replace: “output voltage” with “test voltage” and replace: “charge voltage” with “test voltage”.

A.2.3.1 Prior to verifying the discharge current, the amplitude of the ESD generator’s test voltage

should be determined using a high-voltage meter at the electrode tip. The accuracy of the test voltage

measurement shall be as specified in Table 1.

NOTE The verification of electrode output voltage should consider electrical structure of ESD generator (e.g.

electrical circuit structure) and specification (e.g. input impedance and input stray capacitance) of high-voltage

meter for correct measuring.

A.2.3.4 The measurement discharge current procedure is shown in Table A.1. The following parameters

shall be measured, or obtained from measured values, in order to verify whether or not the current

waveform of an ESD generator is within specifications:
— I , the peak value of the discharge current, in A;
— I , the value of the current at t , in A (from Table 2);

— I , the value of the current at t , in A (from Table 2);
