FOREWORD
The fEC (International Electrotechnical Commission) is a worldwide organization for standardization
1)
comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to
promote international cooperation on all questions concerning standardization in the electrical and
electronic fields. To this end and in addition to other activities, the !EC 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, prepared by technical committees on
which all the National Committees having a special interest therein are represented, express, as nearly as
possible, an international consensus of opinion on the subjects dealt with.
3) They have the form of recommendations for international use published in the form of standards, technical
reports or guides and they are accepted by the National Committees in that sense.
In order to promote international unification, IEC National Committees undertake to apply IEC International
4)
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.
International Standard IEC 1298-4 has been prepared by sub-committee 65B: Devices, of
IEC technical committee 65: Industrial-process measurement and control.
The text of this standard is based on the following documents:
DIS Report on voting
65B/246/RVD
65B/230/DIS
Full information on the voting for the approval of this standard can be found in the report
on voting indicated in the above table.
IEC 1298 consists of the following parts, under the general title Process measurement and
control devices - General methods and procedures for evaluating performance:
- Part 1: General considerations
- Part 2: Tests under reference conditions
Part 3: Tests for the effects of influence quantities

- Part 4: Evaluation repo rt content

INTRODUCTION
This standard is not intended as a substitute for existing standards, but is rather intended
as a reference document for any future standards developed within the IEC or other
standards organizations, concerning the evaluation of process instrumentation. Any
revision of existing standards should take this standard into account.
This common standardized basis should be utilized for the preparation of future relevant
standards, as follows:
— Any test method or procedure, already treated in this standard, should be specified
and described in the new standard by referring to the corresponding clause of this
standard.
Any particular method or procedure, not covered by this standard, should be
—
developed and specified in the new standard in accordance with the criteria, as far as
they are applicable, stated in this standard.
— Any conceptual or significant deviation from the content of this standard, should be
clearly identified and justified if introduced in a new standard.

GENERAL METHODS AND PROCEDURES
FOR EVALUATING PERFORMANCE —
Part 4: Evaluation report content
1 Scope
This International Standard specifies general methods and procedures for conducting
tests, and reporting on the functional and performance characteristics of process measure-
ment and control devices. The methods and procedures specified in this standard are
applicable to any kind of test or to any type of process measurement and control device.
The tests are applicable to any such devices characterized by their own specific input and
output variables, and by the specific relationship (transfer function) between the inputs
and outputs, and include analogue and digital devices. For devices that require special
tests, this standard shall be used, together with any product specific standard specifying
special tests.
This part specifies the content of the written report on the evaluation or tests on a process
measurement or control device, and the results obtained.
It specifies the major items which should be included in the evaluation report, but it does
not specify the exact format in which the contents should be presented. (This is left to the
discretion of the test laboratory which prepares and issues the report.)
2 Normative reference
The following normative document contains provisions which, through reference in this
text, constitute provisions of this part of 1 EC 1298. At the time of publication, the edition
indicated was valid. All normative documents are subject to revision, and parties to agree-
ments based on this part of IEC 1298 are encouraged to investigate the possibility of
applying the most recent edition of the normative document indicated below. Members of
IEC and ISO maintain registers of currently valid International Standard.

3 General considerations
3.1 Report coverage
One repo rt shall refer to one evaluation of a subject equipment. If a second evaluation is
made of the same equipment, then a separately numbered report shall be issued.
3.2 Report binding
Each copy of the report shall be bound into strong covers, so that the pages cannot
is
become separated. No particular method of binding together the pages of the repo rt
specified. This is left to the discretion of the test laboratory issuing the repo rt .

3.3 Page numbering
Each page of the report shall be identified with a unique, sequential page number. It is
rt as page 1, with subsequent
conventional to regard the first page of text in the repo
pages numbered sequentially.
Page numbers shall be shown in the format "Page 'x' of 'y'" , where 'x' is the specific page
number and 'y' is the number of the last page of the report. The report number should be
given also.
If a separate title page is placed at the front of the report, this is not usually included in
the page numbering sequence.
3.4 Draft and final reports
It is sometimes desirable and advantageous to issue a preliminary, draft version of an
for comment prior to the issue of a formal, final version of the report.
