Transmitters for use in industrial-process control systems - Part 1: Methods for performance evaluation
IEC 60770-1:2010 is intended to specify uniform methods of test for the evaluation of the performance of transmitters with pneumatic or electric output signals. It is applicable to transmitters which have either a standard analogue electric current output signal or a standard pneumatic output analogue signal in accordance with IEC 60381-1 or IEC 60382. The tests detailed herein may be applied to transmitters which have other output signals, provided that due allowance is made for such differences. This second edition cancels and replaces the first edition published in 1999 and constitutes a technical revision. The significant technical change with respect to the previous edition is as follows: 4.3 Load conditions,for pneumatic transmitters, load details have been added.
This publication is to be read in conjunction with IEC 61298-1:2008, IEC 61298-2:2008, IEC 61298-3:2008 and IEC 61298-4:2008.
Transmetteurs utilisés dans les systèmes de conduite des processus industriels - Partie 1: Méthodes d'évaluation des performances
La CEI 60770-1:2010 spécifie des méthodes uniformes d'essai pour l'évaluation des performances des transmetteurs à signaux de sortie électriques ou pneumatiques. Elle s'applique aux transmetteurs ayant pour signal de sortie normalisé soit un courant électrique analogique, soit un signal pneumatique analogique, conformément à la CEI 60381-1 ou à la CEI 60382. Les essais détaillés dans cette norme peuvent être applicables à des transmetteurs dotés d'autres signaux de sortie, à condition de tenir compte, de façon appropriée, de ces différences. Cette deuxième édition annule et remplace la première édition, parue en 1999, dont elle constitue une révision technique. La modification technique principale par rapport à l'édition précédente est la suivante: 4.3 Conditions de charge, pour les transmetteurs pneumatiques, des détails de charge ont été ajoutés.
Cette publication doit être lue conjointement avec la CEI 61298-1:2008, la CEI 61298-2:2008, la CEI 61298-3:2008 et la CEI 61298-4:2008.

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
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60770-1 has been prepared by subcommittee 65B: Devices &
process analysis, of IEC technical committee 65: Industrial-process measurement, control and
automation.
This second edition cancels and replaces the first edition published in 1999. This edition
constitutes a technical revision.
The significant technical change with respect to the previous edition is as follows:
• 4.3 Load conditions: For pneumatic transmitters, load details have been added.
This standard should be read in conjunction with IEC 61298-1, IEC 61298-2, IEC 61298-3 and
IEC 61298-4.

CDV Report on voting
65B/656/CDV 65B/720/CDV
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all parts of IEC 60770 series, published under the general title Transmitters for use in
industrial-process control systems, can be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until the
stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data related to
the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
