EXPRESSION OF PERFORMANCE OF
ELECTROCHEMICAL ANALYZERS –
Part 1: General
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 60746-1 has been prepared by subcommittee 65D: Analysing
equipment, of IEC technical committee 65: Industrial-process measurement and control.
This second edition cancels and replaces the first edition published in 1982 and constitutes
a technical revision.
The text of this standard is based on the following documents:
FDIS Report on voting
65D/89A/FDIS 65D/93/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.
For this second edition, the text has been changed to reflect revision and introduction of Inter-
national Standards since 1982. An Informative Annex A has been introduced.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
The committee has decided that the contents of this publication will remain unchanged until
2007. At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.

INTRODUCTION
This standard specifies the statements which manufacturers should make to describe
analyzers so that users may compare the performance characteristics of any analyzer to their
requirements. It includes the terminology and definitions of the terms to be used in such
statements. It describes the tests that are applicable to all types of electrochemical analyzers,
which may be used to determine these performance characteristics by either the manufacturer
or the user.
This standard is applicable to electrochemical analyzers used for the determination of certain
properties of (generally aqueous) solutions such as pH value, electrical conductivity, dissolved
oxygen content, the concentration of specified ions and redox potential. Other standards in this
series describe those aspects that are particular to specific types of analyzer, for example
IEC 60746-2. It is in accordance with the general principles set out in IEC 60359 and takes into
account documents specifying methods for evaluating performance, IEC 60770 and IEC 61298.
This standard is applicable to analyzers specified for installation in any location and to
analyzers having either flow-through or immersible type sensors. It is applicable to the
complete analyzer when supplied by one manufacturer as an integral unit comprised of all
mechanical, electrical and electronic portions. It also applies to sensor units alone and
electronic units alone when supplied separately or by different manufacturers. For the
purposes of this standard, any regulator for mains-supplied power or any non-mains power
supply, provided with the analyzer or specified by the manufacturer, is considered part of the
analyzer whether it is integral with the analyzer or housed separately.
It does not apply t
