Part 2: Guidance for inspection and routine testing


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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 61003-2 has been prepared by subcommittee 65B: Devices and
process analysis, of IEC technical committee 65: Industrial-process measurement, control and
automation.

INDUSTRIAL-PROCESS CONTROL SYSTEMS –
INSTRUMENTS WITH ANALOGUE INPUTS AND TWO
OR MULTI-STATE OUTPUTS –

Part 2: Guidance for inspection and routine testing



1 Scope
This part of IEC 61003 gives guidelines for inspection and routine testing of electrical and
pneumatic instruments with two- or multi-state output, for instance, for acceptance tests or
after repair. For a full evaluation, IEC 61003-1 is used. Whenever possible any test carried
out is to be in accordance with IEC 61298 series.
This part of IEC 61003 is applicable to electrical and pneumatic industrial-process instruments,
using measured values that are continuous signals. The set point value may be either a
mechanical (position, force, etc.) or a standard signal. These instruments may be used as
controllers or as switches for alarms and other similar purposes.
Quantitative criteria for acceptable performance should be established by agreement between
manufacturer and user, and the report on the tests clarifies which tests were carried out. The
requirements of this standard are effective when agreed by the manufacturer and the user.
2 Normative references

acceptance test
test which intends to prove to the user that the instrument complies with certain conditions of
its requirements as they appear in the contract
3.2
routine test
test to which each individual instrument is subjected during or after manufacture to ascertain
whether it complies with certain criteria
4 Sampling for test
If, by agreement between user and manufacturer, tests are to be performed on a sample lot, it
is recommended that a sampling method such as that presented in IEC 60410 be selected.
NOTE Usually a routine test is applied to each instrument.
When sampling is used, instruments to be tested may be chosen by the user's inspector.
5 Performance tests
5.1 General
Test items for routine test and acceptance test are specified in Table 1. The sequence of the
tests shall be such that the results of a test are not affected by a previous test.
