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

Part 3: Effects of currents passing through the body of livestock
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.
The main task of IEC technical committees is to prepare International Standards. In
exceptional circumstances, a technical committee may propose the publication of a technical
report of one of the following types:
• type 1, when the required support cannot be obtained for the publication of an
International Standard, despite repeated efforts;
• type 2, when the subject is still under technical development or where for any other
reason there is the future but no immediate possibility of an agreement on an International
Standard;
• type 3, when a technical committee has collected data of a different kind from that
which is normally published as an International Standard, for example "state of the art".
Technical reports of types 1 and 2 are subject to review within three years of publication to
decide whether they can be transformed into International Standards. Technical reports of
type 3 do not necessarily have to be reviewed until the data they provide are considered to be
no longer valid or useful.
60479-3/TR © IEC:1998 – 7 –
IEC 60479-3, which is a technical report of type 2, has been prepared by IEC technical
committee 64: Electrical installations of buildings.
The text of this technical report is based on the following documents:
Committee draft Report on voting
64/937/CDV 64/994/RVC
Full information on the voting for the approval of this technical report can be found in the report
on voting indicated in the above table.
IEC 60479 consists of the following parts under the general title Effects of current on human
beings and livestock
– Part 1:1994, General aspects;
– Part 2:1987, Special aspects – Chapter 4: Effects of alternating current with frequencies
above 100 Hz – Chapter 5: Effects of special waveforms of current – Chapter 6: Effects of
unidirectional single impulse currents of short duration;
– Part 3: Effects of currents passing through the bodies of livestock.
This document is issued in the type 2 technical report series of publications (according to
G.3.2.2 of part 1 of the ISO/IEC Directives) as a “Prospective standard for provisional
application" in the field of electrical installations of buildings (and the effects of current on
human beings and livestock) because there is an urgent requirement for guidance on how
standards of this format should be used to meet an identified need.
This technical report is not to be regarded as an “International Standard“. It is proposed for
provisional application so that information and experience of its use in practice may be

INTRODUCTION
This technical report provides basic guidance on the effects of electric currents on livestock
and is for use in the establishment of electrical safety requirements.
There are, however, other aspects to be taken into account, such as probability of faults,
probability of contact with live or faulty parts, touch voltage, fault voltage, experience gained,
technical feasibility and economics. These parameters need to be considered carefully when
fixing safety requirements, for example operating characteristics of protective devices for
electrical installations.
For protection against indirect contact of livestock, the threshold of ventricular fibrillation is the
criterion on which safety requirements should be fixed. For this reason, information is
presented in this part of IEC 60479 on the body impedance of livestock and on the current
magnitude of the threshold of ventricular fibrillation. As there is only little information on the
impedance of animals, the lowest impedance value for cattle, forelegs to hindlegs (see table 2),
has been used as the basis for calculation.
For the purpose of this report the following species of animals are considered to be livestock
which might in rural installations suffer from an electric shock: cattle, sheep, pigs and horses.

EFFECTS OF CURRENT ON HUMAN BEINGS
AND LIVESTOCK –
Part 3: Effects of currents passing through the body of livestock
1 General
1.1 Scope
This technical report indicates values for the electrical impedance of the body of livestock as a
function of the touch voltage, the degree of moisture of the hide or skin and the current path.
At this time values are only available for cattle.
It describes the effects of sinusoidal alternating current within the frequency range from 15 Hz
to 100 Hz passing through the body of livestock.
NOTE – Unless otherwise specified, the current values defined in this technical report are r.m.s. values.
1.2 General remarks
For a given current path through the body, the danger depends mainly on the magnitude and
duration of the current flow. However, the time/current relations specified in clause 5 are, in
many cases, not directly applicable in practice for designing protection against electric shock.
The necessary criterion is the admissible limit of touch voltage (i.e. the product of the current
through the body and the body impedance) as a function of time. The relationship between
current and voltage is not linear because the impedance of the body of livestock varies with the
touch voltage, and data on this relationship is accordingly required.
The different parts of the body of livestock (such as the hide, skin, blood, muscles, other
tissues and joints) present to the electric current an impedance composed of resistive and
capacitive components. The dry hides in particular, in the range of voltages up to s
