53 FOREWORD
54 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
55 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
56 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
57 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
58 Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
59 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
60 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
61 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
62 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
63 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
64 consensus of opinion on the relevant subjects since each technical committee has representation from all
65 interested IEC National Committees.
66 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
67 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
68 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
69 misinterpretation by any end user.
70 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
71 transparently to the maximum extent possible in their national and regional publications. Any divergence between
72 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
73 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
74 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
75 services carried out by independent certification bodies.
76 6) All users should ensure that they have the latest edition of this publication.
77 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
78 members of its technical committees and IEC National Committees for any personal injury, property damage or
79 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
80 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
81 Publications.
82 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
83 indispensable for the correct application of this publication.
84 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
85 rights. IEC shall not be held responsible for identifying any or all such patent rights.
86 International Standard IEC 62828-2 has been prepared by subcommittee 65B: Measurement
87 and control devices, of IEC technical committee 65: Industrial-process measurement, control
88 and automation.
89 The text of this International Standard is based on the following documents:

92 report on voting indicated in the above table.
93 This document has been drafted in accordance with the ISO/IEC Directives, Part 2.

108 INTRODUCTION
109 Most of the current IEC standards on industrial and process measurement transmitters are
110 rather old and were developed having in mind devices based on analogue technologies. Today’s
111 digital industrial and process measurement transmitters are quite different from those analogue
112 transmitters: they include more functions and newer interfaces, both towards the computing
113 section (mostly digital electronic) and towards the measuring section (mostly mechanical). Even
114 if some standards dealing with digital process measurement transmitters already exist, they are
115 not sufficient, since some aspects of the performance are not covered by appropriate test
116 methods.
117 In addition, existing IEC test standards for industrial and process measurement transmitters are
118 spread over many documents, so that for manufacturers and users it is difficult, impractical and
119 time-consuming to identify and select all the standards to be applied to a device measuring a
120 specific process quantity (pressure, temperature, flow, level, etc.).
121 To help manufacturers and users, it was decided to review, complete and reorganize the
122 relevant IEC standards and to create a more suitable, effective and comprehensive standard
123 series that provides in a systematic way all the necessary specifications and tests required for
...
