Plastics pipes and fittings — Equipment for fusion jointing polyethylene systems — Part 5: Two-dimensional data coding of components and data exchange format for PE piping systems
This document specifies an encoding system for data of components, assembly methods and jointing operations for polyethylene (PE) piping systems for gas, water and other industrial applications. These data can be used in a traceability system and/or used to perform the fusion of components by using equipment as specified in ISO 12176‑1 and in ISO 12176‑2. This encoding system is explained in ISO/IEC 16022, ISO/IEC 18004 and ISO/IEC 24778 which refer to established code types, e.g. QR code. Data to be encoded are: fusion cycle(s), traceability of manufactured products, other manufacturer’s information that can also be given on websites such as voluntary certificates of quality and approvals. This document specifies the export of data (type, format and sequence) from a data retrieval system. Provisions of this document are applicable to polyethylene components conforming to ISO 4427‑2, ISO 4427‑3, ISO 4437‑2, ISO 4437‑3, ISO 4437‑4 and ISO 15494, and can also be applicable to any other components used in PE systems. ISO 13950 and ISO 12176‑4, which partly cover the fields of application of this document, can be used in parallel.

Introduction
The use of two-dimensional code is becoming increasingly popular because of the quantity of
information that it is possible to group in a small space, and this can provide increased opportunities for
manufacturers and customers. There are many benefits for the market, but the scope of this document is
not to show all of them. The most important technical advantage of using a two-dimensional code is the
possibility to apply a built-in correction level to the coding, so that, even with some scratches or missing
parts, the operator can still use all information coded safely. Another important fact, for those that
want to use the power of the whole traceability, is that any important information regarding the piping
component can be stored in an electronic device, by reading only one code instead of two (ISO 12176-4
and ISO 13950) and thus avoiding overlapping information. This document provides a means for coding
all aspects not covered by ISO 12176-4 or ISO 13950, e.g. large diameters, big saddles or other imperial
sizes. This document also aims to standardize the transfer of data stored in the memories of electronic
units to another electronic equipment (e.g. computer/data base) and to encourage, at any level, the use
of the traceability for a further development of the polyethylene piping systems.

This data encoding system shall use alternatively a code type according to ISO/IEC 16022 (Data Matrix
code), ISO/IEC 18004 (QR code), and ISO/IEC 24778 (Aztec code). A maximum of 1 024 bytes can be
included in the two-dimensional code.
When the two-dimensional code conforms to ISO/IEC 18004 (QR code), the two-dimensional code shall
be of the following characteristics:
a) minimum module width: 0,253 mm (valid for all versions);
b) minimum resolution: 300 dpi (valid for all versions);
© ISO 2021 – All rights reserved 3
---------------------- Page: 8 ----------------------
ISO 12176-5:2021(E)
c) correction level M (for codes smaller or equal to type 14, level L correction level may be used).
Examples of two-dimensional codes are given in Annex E.
In the case that the resulting code size is too large (e.g. to be stuck on small fittings or components), the
code symbols may be appended in a structured format.
For multi-byte encoding characters, examples of checksum calculation are given in Annex F.
Attention is drawn to control units that can have limited character sets and can not be able to represent
multi-byte characters correctly on their display or in their pdf file output. Nevertheless, control units
shall guarantee that the characters are correct in data retrieval for exchange formats, like csv or JSON.
4.2 Contents
Data are coded in fields as defined hereafter. Fields are identified and delimited by the use of the symbol
“]” at the end of any field. All data are grouped in homogeneous regions. There are five regions:
Region 0: revision of data coding definition (subclause 4.2.1)
Region 1: identification components type (subclause 4.2.2)
Region 2: jointing process information (subclause 4.2.3)
Region 3: Traceability (subclause 4.2.4)
Region 4: additional factory information (subclause 4.2.5)
Each field consists of a defined number of characters (see 4.2.1, 4.2.2, 4.2.3, 4.2.4 and 4.2.5) and only
characters defined in the following are acceptable. The characters: “]” and “~” shall be used exclusively
as delimiters. Each character is an alphanumerical digit or one special character. Each character is
represented as 1 to 4 bytes and shall be encoded in UTF-8.
After the five regions there is the checksum (subclause 4.2.6).
4.2.1 Revision of data coding definition (region 0)
The region 0 is without field(s) and it starts and ends with character ‘~’ (see 3.1.2.2). The revision
number is shown as a double-digit counter, starting with “00” with the first publication of this document
and increases by +1 for every revision of the data format.
Region 0, for the first publication of this document, is identified by the characters ~00~. For clarity,
at the next revision of the data format the region 0 will be: ~01~ (this document can be revised in the
future without changes of the data format).
In region 0, a minimum and a maximum of four characters are used comprising two delimiters “~”.
The following is an example of data in region 0, total characters used 4 out of 4 available in this region:

Introduction
The use of two-dimensional code is becoming increasingly popular because of the quantity of
information that it is possible to group in a small space, and this can provide increased opportunities for
manufacturers and customers. There are many benefits for the market, but the scope of this document is
not to show all of them. The most important technical advantage of using a two-dimensional code is the
possibility to apply a built-in correction level to the coding, so that, even with some scratches or missing
parts, the operator can still use all information coded safely. Another important fact, for those that
want to use the power of the whole traceability, is that any important information regarding the piping
component can be stored in an electronic device, by reading only one code instead of two (ISO 12176-4
and ISO 13950) and thus avoiding overlapping information. This document provides a means for coding
all aspects not covered by ISO 12176-4 or ISO 13950, e.g. large diameters, big saddles or other imperial
sizes. This document also aims to standardize the transfer of data stored in the memories of electronic
units to another electronic equipment (e.g. computer/data base) and to encourage, at any level, the use
of the traceability for a further development of the polyethylene piping systems.

FINAL DRAFT INTERNATIONAL STANDARD ISO/FDIS 12176-5.2:2021(E)
Plastics pipes and fittings — Equipment for fusion jointing
polyethylene systems —
Part 5:
Two-dimensional data coding of components and data
exchange format for PE piping systems
1 Scope
This document specifies an encoding system for data of components, assembly methods and jointing
operations for polyethylene (PE) piping systems for gas, water and other industrial applications. These
data can be used in a traceability system and/or used to perform the fusion of components by using
equipment as specified in ISO 12176-1 and in ISO 12176-2.
This encoding system is explained in ISO/IEC 16022, ISO/IEC 18004 and ISO/IEC 24778 which refer to
established code types, e.g. QR code.
Data to be encoded are: fusion cycle(s), traceability of manufactured products, other manufacturer’s
information that can also be given on websites such as voluntary certificates of quality and approvals.
This document specifies the export of data (type, format and sequence) from a data retrieval system.
Provisions of this document are applicable to polyethylene components conforming to ISO 4427-2,
ISO 4427-3, ISO 4437-2, ISO 4437-3, ISO 4437-4 and ISO 15494, and can also be applicable to any other
components used in PE systems.
ISO 13950 and ISO 12176-4, which partly cover the fields of application of this document, can be used in
parallel.

© ISO 2021 – All rights reserved 3
---------------------- Page: 8 ----------------------
ISO/FDIS 12176-5.2:2021(E)
Examples of two-dimensional codes are given in Annex E.
In the case that the resulting code size is too large (e.g. to be stuck on small fittings or components), the
code symbols may be appended in a structured format.
For multi-byte encoding characters, examples of checksum calculation are given in Annex F.
Attention is drawn to control units that can have limited character sets and can not be able to represent
multi-byte characters correctly on their display or in their pdf file output. Nevertheless, control units
shall guarantee that the characters are correct in data retrieval for exchange formats, like csv or JSON.
4.2 Contents
Data are coded in fields as defined hereafter. Fields are identified and delimited by the use of the symbol
“]” at the end of any field. All data are grouped in homogeneous regions. There are five regions:
Region 0: revision of data coding definition (subclause 4.2.1)
Region 1: identification components type (subclause 4.2.2)
Region 2: jointing process information (subclause 4.2.3)
Region 3: Traceability (subclause 4.2.4)
Region 4: additional factory information (subclause 4.2.5)
Each field consists of a defined number of characters (see 4.2.1, 4.2.2, 4.2.3, 4.2.4 and 4.2.5) and only
characters defined in the following are acceptable. The characters: “]” and “~” shall be used exclusively
as delimiters. Each character is an alphanumerical digit or one special character. Each character is
represented as 1 to 4 bytes and shall be encoded in UTF-8.
After the five regions there is the checksum (subclause 4.2.6).
4.2.1 Revision of data coding definition (region 0)
The region 0 is without field(s) and it starts and ends with character ‘~’ (see 3.1.2.2). The revision
number is shown as a double-digit counter, starting with “00” with the first publication of this document
and increases by +1 for every revision of the data format.
Region 0, for the first publication of this document, is identified by the characters ~00~. For clarity,
at the next revision of the data format the region 0 will be: ~01~ (this document can be revised in the
future without changes of the data format).
In region 0, a minimum and a maximum of four characters are used comprising two delimiters “~”.
The following is an example of data in region 0, total characters used 4 out of 4 available in this region:

Introduction
The use of two-dimensional code is becoming increasingly popular because of the quantity of
information that it is possible to group in a small space, and this can provide increased opportunities for
manufacturers and customers. There are many benefits for the market, but the scope of this document is
not to show all of them. The most important technical advantage of using a two-dimensional code is the
possibility to apply a built-in correction level to the coding, so that, even with some scratches or missing
parts, the operator can still use all information coded safely. Another important fact, for those that
want to use the power of the whole traceability, is that any important information regarding the piping
component can be stored in an electronic device, by reading only one code instead of two (ISO 12176-4
and ISO 13950) and thus avoiding overlapping information. This document provides a means for coding
all aspects not covered by ISO 12176-4 or ISO 13950, e.g. large diameters, big saddles or other imperial
sizes. This document also aims to standardize the transfer of data stored in the memories of electronic
units to another electronic equipment (e.g. computer/data base) and to encourage, at any level, the use
of the traceability for a further development of the polyethylene piping systems.

Part 5:
Two-dimensional data coding of components and data
exchange format for PE piping systems
1 Scope
This document specifies an encoding system for data of components, assembly methods and jointing
operations for polyethylene (PE) piping systems for gas, water and other industrial applications. These
data can be used in a traceability system and/or used to perform the fusion of components by using
equipment as specified in ISO 12176-1 and in ISO 12176-2.
This encoding system is explained in ISO/IEC 16022, ISO/IEC 18004 and ISO/IEC 24778 which refer to
established code types, e.g. QR code.
Data to be encoded are: fusion cycle(s), traceability of manufactured products, other manufacturer’s
information that can also be given on websites such as voluntary certificates of quality and approvals.
This document specifies the export of data (type, format and sequence) from a data retrieval system.
Provisions of this document are applicable to polyethylene components conforming to ISO 4427-2,
ISO 4427-3, ISO 4437-2, ISO 4437-3, ISO 4437-4 and ISO 15494, and can also be applicable to any other
components used in PE systems.
ISO 13950 and ISO 12176-4, which partly cover the fields of application of this document, can be used in
parallel.

Attention is drawn to control units that can have limited character sets and can not be able to represent
multi-byte characters correctly on their display or in their pdf file output. Nevertheless, control units
shall guarantee that the characters are correct in data retrieval for exchange formats, like csv or JSON.
4.2 Contents
Data are coded in fields as defined hereafter. Fields are identified and delimited by the use of the symbol
“]” at the end of any field. All data are grouped in homogeneous regions. There are five regions:
Region 0: revision of data coding definition (subclause 4.2.1)
Region 1: identification components type (subclause 4.2.2)
Region 2: jointing process information (subclause 4.2.3)
Region 3: Traceability (subclause 4.2.4)
Region 4: additional factory information (subclause 4.2.5)
Each field consists of a defined number of characters (see 4.2.1, 4.2.2, 4.2.3, 4.2.4 and 4.2.5) and only
characters defined in the following are acceptable. The characters: “]” and “~” shall be used exclusively
as delimiters. Each character is an alphanumerical digit or one special character. Each character is
represented as 1 to 4 bytes and shall be encoded in UTF-8.
After the five regions there is the checksum (subclause 4.2.6).
4.2.1 Revision of data coding definition (region 0)
The region 0 is without field(s) and it starts and ends with character ‘~’ (see 3.1.2.2). The revision
number is shown as a double-digit counter, starting with “00” with the first publication of this document
and increases by +1 for every revision of the data format.
Region 0, for the first publication of this document, is identified by the characters ~00~. For clarity,
at the next revision of the data format the region 0 will be: ~01~ (this document can be revised in the
future without changes of the data format).
In region 0, a minimum and a maximum of four characters are used comprising two delimiters “~”.
The following is an example of data in region 0, total characters used 4 out of 4 available in this region:

Introduction
The use of two-dimensional codes is becoming more and more popular because of the quantity of
information that is possible to group in a small space, and this may provide increased opportunities for
manufacturers and customers. There are many benefits for the market, but the scope of this document
is not to show all of them. The most important technical advantage of using a two-dimensional code
is the possibility to apply a built-in correction level to the coding, so that, even with some scratches
or missing parts, the operator can still use all information coded safely. Another important fact, for
those that want to use the power of the whole traceability, is that any important information regarding
the piping component can be stored in an electronic device, by reading only one code instead of two
(ISO 12176-4 and ISO 13950) and thus avoiding overlapping information. This new part of ISO 12176
provides a means for coding all aspects not covered by ISO 12176-4 or ISO 13950, e.g. large diameters,
big saddles, other imperial sizes. This document also aims to standardise the transfer of the data stored
in the memories of the electronic units, to another electronic equipment (e.g. computer/data base), to
encourage, at any level, the use of the traceability for a further development of the polyethylene piping
systems.

Part 5:
Two-dimensional data coding of components and data
exchange format for PE piping systems
1 Scope
This document specifies an encoding system for data of components, assembly methods and jointing
operations for polyethylene (PE) piping systems for gas, water and other industrial applications. These
data can be used in a traceability system and/or used to perform the fusion of components by using
equipment as specified in ISO 12176-1 and in ISO 12176-2.
This encoding system is explained in ISO/IEC 16022, ISO/IEC 18004 and ISO/IEC 24778 which refer to
established code types, e.g. QR code.
Data to be encoded are: fusion cycle(s), traceability of manufactured products, other manufacturer’s
information that may also be given on web-sites such as voluntary certificates of quality and approvals.
This document specifies the export of data (type, format and sequence) from a data retrieval system.
[1]
Provisions of this document are applicable to polyethylene components conforming to ISO 4427-2 ,
[2] [3] [4] [5] [6]
ISO 4427-3 , ISO 4437-2 , ISO 4437-3 , ISO 4437-4 and ISO 15494 , and it can be applicable also
to any other components used in PE systems.
ISO 13950 and ISO 12176-4, which partly cover the fields of application of this document, can be used in
parallel.
