Part 1: General procedures for all types of transmitters

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 62828-1 has been prepared by subcommittee 65B: Measurement
and control devices, of IEC technical committee 65: Industrial-process measurement, control
and automation.
The IEC 62828 series cancels and replaces the IEC 60770 series and proposes revisions for
the IEC 61298 series.
The text of this International Standard is based on the following documents:

INTRODUCTION
Most of the current IEC standards on industrial and process measurement transmitters are
rather old and were developed having in mind devices based on analogue technologies.
Today’s digital industrial and process measurement transmitters are quite different from those
analogue transmitters: they include more functions and newer interfaces, both towards the
computing section (mostly digital electronic) and towards the measuring section (mostly
mechanical). Even if some standards dealing with digital process measurement transmitters
already exist, they are not sufficient, since some aspects of the performance are not covered
by appropriate test methods.
In addition, existing IEC test standards for industrial and process measurement transmitters
are spread over many documents, so that for manufacturers and users it is difficult,
impractical and time-consuming to identify and select all the standards to be applied to a
device measuring a specific process quantity (pressure, temperature, flow, level, etc.).
To help manufacturers and users, it was decided to review, complete and reorganize the
relevant IEC standards and to create a more suitable, effective and comprehensive standard
series that provides in a systematic way all the necessary specifications and tests required for
different industrial and process measurement transmitters.
To solve the issues mentioned above and to provide an added value for the stakeholders, the
new standard series on industrial and process measurement transmitters covers the following
main aspects:
• Applicable normative references
• Specific terms and definitions
• Typical configurations and architectures for the various types of industrial and process
measurement transmitters
• Hardware and software aspects
• Interfaces (to the process, to the operator, to the other measurement and control devices)
• Physical, mechanical and electrical requirements and relevant tests; clear definition of the
test categories: type tests, acceptance tests and routine tests
• Performance (its specification, tests and verification)
• Environmental protection, hazardous areas application, functional safety, etc.
• Structure of the technical documentation.
To cover in a systematic way all the topics to be addressed, the standard series is organized
in several parts. At the moment of the publication of this document, IEC 62828 consists of the
following parts:
• Part 1: General procedures for all types of transmitters
• Part 2: Specific procedures for pressure transmitters
• Part 3: Specific procedures for temperature transmitters
• Part 4: Specific procedures for level transmitters
• Part 5: Specific procedures for flow transmitters
In preparing the IEC 62828 series many test procedures were taken, with the necessary
improvements, from the IEC 61298 series. As the actual IEC 61298 series is applicable to all
process measurement and control devices, when the IEC 62828 series is completed the
IEC 61298 series will be revised to harmonise it with the IEC 62828 series, taking out from its
scope the industrial and process measurement transmitters. During the time when 61298
scope is being updated, the new series IEC 62828 takes precedence for industrial and
process measurement transmitters.
When the IEC 62828 series is published, the IEC 60770 series will be withdrawn.

REFERENCE CONDITIONS AND PROCEDURES FOR TESTING INDUSTRIAL
AND PROCESS MEASUREMENT TRANSMITTERS –

Part 1: General procedures for all types of transmitters

1 Scope
This Part of IEC 62828 establishes a general framework for defining reference conditions and
test procedures applicable to all types of industrial and process measurement transmitters
(PMTs) used in measuring and control systems for industrial process and machinery. These
reference test conditions are divided into “standard reference conditions”, which apply when
determining the accuracy of measurement, and “ambient and process reference conditions”,
which are used to assess the influence of external quantities on the measurement.
For the purpose of this document, an analogue PMT is a process measurement transmitter
with an analogue current or voltage output, irrespective of the technology adopted and the
complexity of the circuitry. All the other process measurement transmitters, with digital output ®
only or with hybrid analogue and digital output (e.g. HART ), are considered to be digital
PMTs.
For general test procedures, reference is made to IEC 62828-1, which is applicable to all
types of industrial and process measurement transmitters.
Additional specific test procedures for given types of PMTs (pressure, temperature, level,
flow) are covered by other parts of this series.
NOTE 1 In industrial and process applications, to indicate the process measurement transmitters it is common
also to use the terms “industrial transmitters”, or “process transmitters”.
NOTE 2 For better clarity, when the complete definition “industrial and process measurement transmitter” makes
the sentence too long in this document, the short term “transmitter” is used instead.
Proximity devices with analogue output are excluded from the scope of this document.
