TRANSMITTERS FOR USE IN INDUSTRIAL-PROCESS

Part 2: Methods for inspection and routine testing
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 60770-2 has been prepared by subcommittee 65B: Devices, of IEC
technical committee 65: Industrial-process measurement and control.
This second edition cancels and replaces the first edition published in 1989 and constitutes
a technical revision.
The text of this standard is based on the following documents:
FDIS Report on voting
65B/468/FDIS 65B/477/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.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
A bilingual edition may be issued at a later date.
The committee has decided that the contents of this publication will remain unchanged until
2008. At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.

INTRODUCTION
The methods of inspection and routine testing specified in this standard are intended for use in
acceptance tests or after repair to verify the fulfilment of the performance specifications as
established by the user. The methods given in this standard are primarily intended for the
testing of conventional analogue transmitters. For setting up test procedures for
microprocessor-based instruments IEC 62098 should be consulted.

TRANSMITTERS FOR USE IN INDUSTRIAL-PROCESS
CONTROL SYSTEMS –
Part 2: Methods for inspection and routine testing
1 Scope and object
This part of IEC 60770 is applicable to transmitters, which have either a standard analogue
electric current output signal or a standard pneumatic output 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.
For certain types of transmitters, where the sensor is an integral part, other specific IEC or ISO
standards may need to be consulted (e.g. for chemical analyzers, flow-meters, etc.)
This standard is intended to provide technical methods for inspection and routine testing
of transmitters, for instance, for acceptance tests or after repair. For a full evaluation,
IEC 60770-1 shall be used.
Quantitative criteria for acceptable performance should be established by agreement between
manufacturer and user.
By agreement the tests need not be carried out by an accredited laboratory.
2 Normative references
At the time of the publication the editions indicated were valid. All normative documents are sub-
ject to revision, and parties to agreements based on these normative documents are encouraged
to investigate the possibility of applying the most recent editions of the normative documents
