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 60873-1 has been prepared by subcommittee 65B: Devices, of IEC

technical committee 65: Industrial-process measurement and control.

This first edition of IEC 60873-1 cancels and replaces IEC 60873 (1986) and constitutes a

technical revision.

The main changes with respect to the previous edition concern the updating of methods for

inspection and routine testing of devices, and recorder testing requirements now comply with

IEC 61298.

INTRODUCTION

The methods of evaluation specified in this part of IEC 60873 are intended for use by

manufacturers to determine the performance of their products and by users or independent

testing establishments to verify manufacturers’ performance specifications.

The test conditions in this standard, for example, the range of ambient temperatures and power

supply, represent those which commonly arise in use. Consequently, the values specified

herein shall be used where no other values are specified by the manufacturer.

The tests specified in this standard are not necessarily sufficient for instruments specifically

designed for unusually arduous duties. Conversely, a restricted series of tests may be suitable

for instruments designed to perform within a more limited range of conditions.

It will be appreciated that the closest communication should be maintained between the

evaluating body and the manufacturer. Note should be taken of the manufacturer's

specifications for the instrument when the test programme is being decided, and the

manufacturer should be invited to comment on both the test programmes and the results.

ELECTRICAL AND PNEUMATIC ANALOGUE CHART RECORDERS
FOR USE IN INDUSTRIAL-PROCESS SYSTEMS –
Part 1: Methods for performance evaluation
1 Scope and object

This part of IEC 60873 provides methods for determining the performance of all electrical and

pneumatic analogue chart recorders operating from a standardized signal which may be used

in process control. It is intended that continuous and dotted-line traces, multiple-pen and

multiple-channel instruments should be covered. Some tests should not apply to all instruments

and additional tests may be required for certain types of recorders.

The object of this standard is to specify uniform methods of test for the evaluation of the

performance of electrical and pneumatic analogue chart recorders operating from a

standardized signal which may be used in process control.

When a full evaluation in accordance with this standard is not required, those tests which are

required should be performed and the results reported in accordance with those parts of the

standard which are relevant. It should be made clear in such a report that the evaluation

reported is not a full evaluation and the parts omitted should be indicated.

region between the limits within which a quantity is measured, or received, expressed by

stating the lower and upper range values (for example, 0 Pa, 20 Pa).

NOTE Instruments may be supplied with manual or automatic means of adjusting the range. As used in this

standard, the term "range" and the definitions below apply to the characteristics of the instruments for a specified

setting of the adjustment means.

The zero value of the measured variable is "elevated" if it is greater than the lowest range

value and "suppressed" if it is less than the lowest range value

4 General testing procedures

General requirements for measurement procedure will be found in Clause 7 of IEC 61298-1.

Other specific procedures can be found below.
4.1 Selection of ranges for test

Where there are switched ranges (or dial settings), for example, gain, the tests shall be

repeated to cover all ranges. Where the DUT is supplied calibrated for use, the first set of tests

shall be carried out without adjustment.

a) The recorder shall be put into operation according to the manufacturer's instructions; in

particular, those relating to the preliminary adjustments.

NOTE The chart and ink supplied by the manufacturer for the recorders should be used for all tests.

b) Unless otherwise stated, where the span is adjustable other than to take up manufacturing

tolerances, the tests should be carried out with the span adjustment set approximately at

the manufacturer's stated minimum and maximum and at an intermediate value.

c) Unless otherwise stated, where the zero adjustment is adjustable other than to take up

manufacturing tolerances, such as devices equipped with means for suppression or

elevation of zero, the tests should be carried out with the elevation/suppression adjustment

set for its minimal effect, then at its extreme values.

If the extent of adjustment is more than twice the maximum span, tests should also be carried

out with the adjustment set approximately at the arithmetic mean of the two extreme values of

elevation and/or suppression (see also 4.1.1.2 of IEC 61298-2).

NOTE Testing of an instrument with provision for substantial adjustment of both span and zero in accordance with

4.1b) and 4.1c) may require an impractically large number of tests. Preliminary tests should be conducted to

determine the effect of changing span and zero adjustments on the characteristic being measured so that

redundant tests can be eliminated from the test programme in cases where the characteristic can be inferred

reliably from fewer tests. For example, hysteresis and dead band may not be significantly affected by selection of

the lower and upper range value if the span is held constant and may often be calculated for different spans from

measurements at a single-span setting. In any case, the report should clearly indicate relevant values of the

measured parameters for each setting of the adjustments so that the values of measured error, hysteresis, dead

band, etc., are all referenced to the same adjustment of the recorder.
4.2 Zero and span adjustment

Zero and span should be adjusted to make the actual characteristic conform closely to ideal

values at the upper and lower range limits before carrying out each test specified in this

standard. When this is done, the fact shall be stated in the evaluation report.
4.3 Information to be reported

Unless otherwise agreed, the test results shall be expressed as percentages of output span.

When performance characteristics are specified, they shall be tabulated beside the actual test

results.

The limit of error of the measuring systems used for the test shall be stated in the test report

and should be smaller than, or equal to, one-quarter of the stated limit of error of the

instrument tested.
4.4 Other procedures

a) An adequate time, as specified by the manufacturer, shall be allowed after switching on the

power supply in order to allow temperature within the instrument to stabilize. In the absence

of a manufacture’s specification, a period of at least 30 min should be allowed.

b) In performing tests on a multiple-channel recording instrument, the measured quantity shall

be applied to the instrument under test and to a reference instrument and shall be varied so

that the required value is shown on the reference instrument. The determination of

deviations shall be carried out by using first one of the channels and then, succ
