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

INTRODUCTION
The primary purpose of a nameplate is to clearly identify the device and its manufacturer. Legal
marks or approval symbols indicate conformity with the regulations for placing the device on
the market and for safe use.
The project "Digital Nameplate" was started in response to the needs of manufacturers of
explosion-protected equipment and operators of electrical plants in explosion hazardous areas.
One objective is to ensure that all of the necessary information can be marked on the
equipment, particularly considering the extent of the information required in the field of
explosion protection. The requirements for marking products for the global markets have
become as extensive that it is often no longer possible to include all of the necessary
information on the nameplate, especially of smaller products (e.g. sensors). As an example, in
Europe, different EU Directives and harmonized standards can apply to the same product, e.g.
for electric safety, explosion safety, safety of machinery, pressure safety or food safety. If the
product is to be sold worldwide, additional markings and approval symbols are required, e.g.
IEC Ex marking, Ex marking for the North American market, UK CA marking for UK, EAC for
the Eurasian Economic Area, RCM for Australia or CCC for China.
Within the context of smart manufacturing, it is also anticipated that products will have to be
electronically identifiable in future. Equipment manufacturers can use machine-readable
marking in the production process to automatically control the material flow by using a barcode.
Operators can easily identify the product at the incoming inspection.Service engineers or the
responsible authorities can electronically check all the required data and information for the
application and safe use. The data from the machine-readable nameplate can be transmitted
directly to an ERP system (Enterprise Resource Planning system) for error-free stocktaking.
Operators and users have access to the device data in digital format.
One intention of the (offline) digital nameplate is to reduce the required space of the
conventional nameplate. In the long term it is expected that the digital nameplate can replace
the conventional text on the nameplate saving a lot of space, especially on small products.
This document describes alternative electronically-readable solutions to the current,
conventional, plain text marking on the nameplate or packaging. It describes marking
technologies that use 2D codes, transponders or the firmware of the products. In the case of a
2D code or transponder, the stored data can be read by commonly available scanning devices,
e.g. smartphones. If the marking is stored in the firmware of the product, the nameplate can be
shown, for example, on the product display or the data can be read via an electronic interface
remotely.
Furthermore, the IEC 61406-1 is in development for a unique product identification via an
Identification Link. That standard enables manufacturers to provide all product related data and
documents via an Internet address in an electronic format. Product documentation such as
technical information, operating instructions and product certificates can be downloaded. That
standard defines a specific 2D or RFID code, which contains only the Identification Link string
with limited characters. In IEC 63365, the Identification Link string is included as the first
property in the digital nameplate, followed by the detailed marking properties. If an Internet
connection to the manufacturer's website is available, additional product data (digital twin) and
documentation can be accessed.

---------------------- Page: 8 ----------------------
IEC 63365:2022 © IEC 2022 – 7 –
This document is also intended to increase acceptance of digital nameplates among legislative
bodies. A long-term goal is to replace the conventional nameplate with an electronically
readable nameplate as far as possible. Regulators require marking to be applied to devices
permanently, clearly and legibly. This requirement could be met with digital marking as well.
Digital nameplates that are permanently affixed to the product and provide the necessary data
without the need for an Internet connection come very close to plain text marking. To ensure
greater acceptance, the nameplate shows a minimum amount of marking in plain text. During a
transition period, both, the plain text and the digital marking can be applied simultaneously at
the product. Today electronic marking is being increasingly implemented and accepted on the
international markets.
ISO/IEC 22603-1 was recently published and specifies a digital label representating the product
marking. But that standard provides the product marking via a link to a Webserver which
contains the relevant information and does not contain the marking directly in the digital code.

INDUSTRIAL PROCESS MEASUREMENT, CONTROL AND AUTOMATION –
DIGITAL NAMEPLATE



1 Scope
This International standard applies to products used in the process measurement, control and
automation industry. It establishes a concept and requirements for the digital nameplate and
provides alternative electronically readable solutions (e.g. 2D codes, RFID or firmware) to
current conventional plain text marking on the nameplate or packaging of products.
The digital nameplate information is contained in the electronically readable medium affixed to
the product, the packaging or accompanying documents. The digital nameplate information is
available offline without Internet connection. After electronic reading, all digital nameplate
information is displayed in a human readable text format. The digital nameplate also includes
the Identification Link String according to IEC 61406-1 which provides additional online
information for the product.
This document does not specify the contents of the conventional nameplate, which are subject
to regional or national regulations and standards.

4 Contents of the digital code
4.1 General
The information according to Annex A can be added in a digital code to the nameplate.
The digital code
– can store all information required by regional or national regulations and
– can contain additional information provided by the manufacturer.
Marks and symbols cannot be converted into the digital code on the nameplate, but may be
provided in the firmware. All information provided in the digital code that is not required
specifically in plain text by regional or national regulations can be removed from the human
readable text of the nameplate.
For security reasons, a 2D reader that asks the user to activate a link to the URL is
recommended. In general, if the link is not activated, the embedded text is shown.
4.2 Data structure of the digital code
The information listed in Annex A can be converted into digital format. The data shall be
structured according to the following three categories:
– basic information;
– technical specification;
– certificates.
The first information of the digital nameplate shall be an Identification Link string as per
IEC 61406-1. This enables standard scanners to interpret the first line as a URL and, if an
Internet connection is available, to link to a product database.
An example of a conventional nameplate is shown in the upper part of Figure 1. This nameplate
represents an industrial level meter with several international certificates as an explosion
protected device. Due to the amount of information, this nameplate occupies a large area of
2
80 cm .
In the lower part of Figure 1, the corresponding digital nameplate is shown with the basic
information and the conformity symbols still visible in plain text. The complete marking is
converted into the digital code. The digital nameplate including QR Code occupies an area of
2
42,5 cm , which is approximately half of the size of the conventional nameplate above.

---------------------- Page: 12 ----------------------

The scan of the QR Code using a smartphone with standard scanner software is also shown in
Figure 1. The complete text marking including basic information is visible on the screen and
can be stored or transfered as a text file.
