ISO 21007-2:2013(E) iv © ISO 2013 – All rights reserved Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 21007-2 was prepared by Technical Committee ISO/TC 58, Gas cylinders, Subcommittee SC 4, Operational requirements for gas cylinders. This second edition cancels and replaces the first edition (ISO 21007-2:2005). Only Annex C has been revised. ISO 21007 consists of the following parts, under the general title Gas cylinders — Identification and marking using radio frequency identification technology: ⎯ Part 1: Reference architecture and terminology ⎯ Part 2: Numbering schemes for radio frequency identification SIST EN ISO 21007-2:2013
ISO 21007-2:2013(E) © ISO 2013 – All rights reserved v Introduction Throughout industry and in commerce, trade and the domestic sector, the employment of gas cylinders (referred to as GC in this part of ISO 21007) to enable the local consumption and use of gases and liquids, without the need for in-situ high cost permanent pressure vessel installations, is an important part of modern practice. Such cylinders provide complex gas mixes for medical, industrial or research use. As the cylinders can contain a wide variety of gases, identification is of paramount importance. It is mandatory to be able to uniquely identify each cylinder. As many contents are of limited life, and for product quality and liability tracking and tracing, in some circumstances it could be necessary or desirable to identify not only the type of gas or liquid, but also such details as filling station, batch and date of fill. Various methods and technologies such as physical identification through indentation; paper, card, metal, and plastic labeling; colour code identification; bar coding and, in some circumstances, vision systems are already used to make or assist such identifications. The technology of radio frequency identification (RFID) involves a reader/interrogator station that transmits a predetermined signal of inductive, radio or microwave energy to one or many transponders located within a read zone. The transponder returns the signal in a modified form to the reader/interrogator and the data is decoded. The data component in a portable gas or liquid cylinder environment provides the basis for unambiguous identification of the transponder and also can provide a medium for a bi-directional interactive exchange of data between the host and transponder. The signal can be modulated or unmodulated according to architecture of the system. In many cases it will be necessary or desirable to use one air carrier frequency and protocol, but this will not always be possible or even desirable in all situations, and it could be useful to separate fundamentally different cylinders by the response frequency. However, there is benefit in using a standard common core data structure that is capable of upwards integration and expandable from the simplest low cost cylinder identification system to more complex functions. Such a structure will have to be flexible and enabling rather than prescriptive, thus enabling different systems degrees of interoperability within and between their host systems. The use of Abstract Syntax Notation One (ASN.1, as defined in the ISO/IEC 8824 series) from ISO/IEC 8824-1 as a notation to specify data and its associated Packed Encoding Rules (PER) from ISO/IEC 8825-2 is widely used and gaining popularity. Its usage will provide maximum interoperability and conformance to existing standards and will meet the specifically defined requirements for a generic standard model for portable gas cylinder identification in that it ⎯ enables and uses existing standard coding, ⎯ is adaptable and expandable, ⎯ does not include unnecessary information for a specific application, and ⎯ has a minimum of overhead in storage and transmission. ISO 21007-1 provides a framework reference architecture for such systems. This part of ISO 21007 is a supporting part of ISO 21007-1 and provides a standardized yet flexible and interoperable framework for numbering schemes. This part of ISO 21007 details individual numbering schemes within the framework for the automatic identification of gas cylinders. SIST EN ISO 21007-2:2013
ISO 21007-2:2013(E) vi © ISO 2013 – All rights reserved Central to the effective use of many of the constructs is a structure to provide unambiguous identification. This part of ISO 21007 provides a standardized data element construct for the automatic identification of gas cylinders. Where there is any conflict between this International Standard and any applicable regulation, the regulation always takes precedence.

For details of cylinder/tag operations see Annex A. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

It is designed to accommodate within its framework, data element constructs for a variety of GC applications, from simple GC identification to more complex transactions with a wide variety of uses, and to allow combinations of data elements to be used in a composite data construct. It is designed to allow as much interoperability of the data SIST EN ISO 21007-2:2013
ISO 21007-2:2013(E) © ISO 2013 – All rights reserved 3 elements within an electronic data interchange/electronic data transfer (EDI/EDT) environment as is possible and has to provide a capability for a significant expansion of the number of GC applications in the future. This part of ISO 21007 takes cognizance of and accommodates the operation of systems of different capabilities and will enable within its structure the interoperability of one transponder in any country, even though the operator systems themselves may be significantly different, so long as there is a common air interface (at reference point Delta) and protocol. Even where information has to be collected by a separate interrogator because air carrier compatibility does not exist, the data once collected is in a commonly interoperable format and so may be used accurately and effectively within an EDI/EDT environment. The data element structure defined in this part of ISO 21007 specifies the general presentation rules for transfer of ASN.1 data schemes. It is also the purpose of this part of ISO 21007 to determine how ASN.1 will be used for data transmission in GC applications. Excluding transfers in a predefined context, the first level of identification required in ASN.1 messages identifies the context of the message. This part of ISO 21007 determines that in GC applications this is achieved by using an object identifier that shall be determined in accordance with an arc determined in Annex B of ISO/IEC 8824-1:2008. The objective of this part of ISO 21007 is therefore to establish a basis where the message can always be identified simply by reference to the relevant standard and without the requirement of central registration authorities (except where those are specifically required in the referred to document). 4.2 ASN.1 messages Where there is a simple message where no further subdivision according to ASN.1 rules is possible, the message is called an ASN.1 “primitive message”. Such messages will have only one identification and length statement. The GC identification structure defined in Clause 3 of ISO 21007-1:2005 is an ASN.1 primitive message. 4.3 Message identification requirements The data constructs shall conform to ISO/IEC 8824-1. With the exception of transfers in a predetermined context (see 4.4): ⎯ All GC standard ASN.1 messages shall commence with a unique object identifier that shall be determined in accordance with the arc 2 (joint ITU-T), followed by the object class indicating a standard arc 0, followed by the reference to the standard: {ITU-T)(2)
standard(0)
standardxxx(yyy) } ⎯ Where the data content relates to standards produced by other identified organizations, they shall commence with a unique object identifier that shall be determined in accordance with the arc 2 (joint ITU-T) followed by the identification of an identified organization arc 3, followed by the identification of the identified organization (as provided in Annex B), followed by the object class indicating a standard arc 0, followed by the reference to the standard: { ITU-T(2)
identified-organization (3)
organization-identity(xxx)
standard(0)
standardxxx(zzz) } 4.4 Predetermined context and the use of packed encoding rules Where the context of a transfer is known, the data constructs determined in this part of ISO 21007 may be assumed to be in accordance with the rules determined in ISO/IEC 8825-2. In respect of any identification of an item using an ISO ASN.1 message, the data necessary for unambiguous identification shall reside on the on-board equipment associated with the item being identified.

The predetermined GC context follows: octet 0-yy GC identification structure
5 Gas cylinder identification structure 5.1 General requirements The general requirement of the structure proposed shall be that it is constructed from one or more data elements to form an ASN.1 message. Each of these data elements shall be preceded by 2 octets that identify a) the data scheme identifier (also referred to as DSI), and b) the length of the data field. Data scheme identifier
(1 octet) Length of data field
(1 octet) Data field
This part of ISO 21007 has been designed by adopting the principles of ISO/IEC 8824-1 and ISO/IEC 8825-2, which utilize octets (bytes) of data elements to provide an application identifier, a coding identifier and a length/use identifier in an “abstract syntax notation” for “open systems interconnection”. By adopting the ISO/IEC 8824-1 and ISO/IEC 8825-2 abstract syntax notation with the inclusion of a data element length indicator, the flexibility is provided for data elements of any length to be supported. This data structure standard is itself given a migration path so that as technological developments allow further capabilities, subsequent standards may provide additional data fields for use in all or some sector-specific applications while maintaining the upwards compatibility from and to this part of ISO 21007. The structure enables the chaining of multiple data elements from different application sectors to build complex data element constructs. For example, a GC identification shall be followed by an ISO country code, or perhaps a GC identification followed by a transient data set of the current contents, fill date and location followed by a country identifier, etc. It is expected that several data element structures will start with a GC identification data element. 5.2 Data structure construct 5.2.1 General The data structure construct is as follows: Data scheme identifier Length of data field Data field Data scheme identifier Length of data field Data field SIST EN ISO 21007-2:2013
ISO 21007-2:2013(E) © ISO 2013 – All rights reserved 5 5.2.2 Data scheme identifier (DSI) The octet used for the data scheme identifier shall be used to identify to which of the standardized GC coding scheme data formats the data element construct conforms. Each number issued shall be supported by an ISO format standard detailing the data scheme that is to be used within that format. NOTE Clause 6 details the initial list of primitive data scheme allocations. 5.2.3 Length The length octet shall determine the number of octets in the subsequent data fields. It shall be a length indicator as defined in ISO/IEC 8825-2. For coding, this field will be kept to less than 127, i.e. 1-byte length is expected. For constructs, the extension bit may be used to signify a 3-byte length indicator. 5.2.4 Data field The data field shall follow the number of octets of data that comprises the data field as determined in the previous octet. The data structure of the data field shall be defined in a series of standard data formats issued and published by the gas cylinder data scheme issuing authority and forming subordinate standards in support of this part of ISO 21007. This field may also contain constructs of primitives as defined in ISO/IEC 8824-1 and ISO/IEC 8825-2. 6 Gas cylinder identification data schemes 6.1 General requirements The essence of the general requirement of GC systems is constructed around a basic core unambiguous identification. This GC identification numbering scheme provides a “fixed” core unambiguous identification element. It is envisaged that this core element of unambiguous identification will form the first data set of one or many data sets in a GC environment using data structures that comply with the structure established in ISO 21007-1. Either data scheme 01 or data scheme 02 shall be used in accordance with 6.2 or 6.3, respectively. In addition, data schemes 10, 11, 12, etc. can optionally be used (see Table 1). This data structure is designed to be used not only as a form for simple GC identification, but to form the GC identification element of all standard GC messages where GC identification is a component. To this extent, while this part of ISO 21007 has been primarily designed for use in a transponder/interrogator environment, it is expected that other GC systems, while they use different transmission media and effect similar data exchanges, shall adopt this standard numbering scheme.

This compact numbering data scheme can be replaced or combined with a more versatile identification scheme allowing the use of existing non-numeric gas cylinder identifications. This alternate unambiguous identification data set will be given the DSI appellation: data scheme 02. Other data schemes concerning the package and content of gas cylinders proposed in 6.4 to 6.11 provide capability for other applications that simplify GC identification. The data scheme identifier (DSI) is described in Table 1; the length is the number of bits of the information field. Clauses 6.2 to 6.11 give some examples for the content of these data schemes. Clauses 6.2 and 6.3 describe the minimum definition for the unique identification number of a GC. The choice is between a binary (6.2) and an ASCII (6.3) version. All other definitions in 6.4 to 6.11 are optional.

The format provides a transponder code mandatory field providing specific adaptation to the requirements for GC identification in the GC environment. The code length is 64 bits or more and will be preceded by 2 octets that identify, respectively, the GC DSI (i.e. 4116 primitive) and the code length in octets (i.e. 0816 or more).

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental,
in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.
ISO shall not be held responsible for identifying any or all such patent rights.
ISO 21007-2 was prepared by Technical Committee ISO/TC 58, Gas cylinders, Subcommittee SC 4, Operational
requirements for cylinders.
This second edition cancels and replaces the first edition (ISO 21007-2:2005), Annex C of which has been
technically revised.
ISO 21007 consists of the following parts, under the general title Gas cylinders — Identification and marking using

ISO/DIS 21007-2
Introduction
Throughout industry and in commerce, trade and the domestic sector, the employment of gas cylinders (referred
to as GC in this part of ISO 21007) to enable the local consumption and use of gases and liquids, without the
need for in-situ high cost permanent pressure vessel installations, is an important part of modern practice.
Such cylinders may provide complex gas mixes for medical, industrial or research use.
As the cylinders may contain a wide variety of gases, identification is of paramount importance. It is mandatory to
be able to uniquely identify each cylinder. As many contents are of limited life, and for product quality and liability
tracking and tracing, in some circumstances it may be necessary or desirable to identify not only the type of gas
or liquid, but also such details as filling station, batch and date of fill.
Various methods and technologies such as physical identification through indentation; paper, card, metal, and
plastic labeling; colour code identification; bar coding and, in some circumstances, vision systems are already
used to make or assist such identifications.
The technology of radio frequency identification (RFID) involves a reader/interrogator station that transmits a
predetermined signal of inductive, radio or microwave energy to one or many transponders located within a read
zone. The transponder returns the signal in a modified form to the reader/interrogator and the data is decoded.
The data component in a portable gas or liquid cylinder environment provides the basis for unambiguous
identification of the transponder and may also provide a medium for a bi-directional interactive exchange of data
between the host and transponder. The signal may be modulated or unmodulated according to architecture of the
system.
In many cases it will be necessary or desirable to use one air carrier frequency and protocol, but this will not
always be possible or even desirable in all situations, and it may be useful to separate fundamentally different
cylinders by the response frequency.
However, there is benefit in using a standard common core data structure that is capable of upwards integration
and expandable from the simplest low cost cylinder identification system to more complex functions. Such a
structure will have to be flexible and enabling rather than prescriptive, thus enabling different systems degrees of
interoperability within and between their host systems.
The use of Abstract Syntax Notation One (ASN.1, as defined in the ISO/IEC 8824 series) from
ISO/IEC 8824-1 as a notation to specify data and its associated Packed Encoding Rules (PER) from
ISO/IEC 8825-2 is widely used and gaining popularity. Its usage will provide maximum interoperability and
conformance to existing standards and will meet the specifically defined requirements for a generic standard
model for portable gas cylinder identification in that it
⎯ enables and uses existing standard coding,
⎯ is adaptable and expandable,
⎯ does not include unnecessary information for a specific application, and
⎯ has a minimum of overhead in storage and transmission.
ISO 21007-1 provides a framework reference architecture for such systems. This supporting Part 2 provides a
standardized yet flexible and interoperable framework for numbering schemes. This part of ISO 21007 details
individual numbering schemes within the framework for the automatic identification of gas cylinders.

1 Scope
This part of ISO 21007 establishes a common framework for data structure to enable the unambiguous
identification in gas cylinder (GC) applications and for other common data elements in this sector.
This part of ISO 21007 enables a structure to allow some harmonization between different systems. However,
it does not prescribe any one system and has been written in a non-mandatory style so as not to make it
obsolete as technology changes.
The main body of this part of ISO 21007 excludes any data elements that form any part of transmission or
storage protocols such as headers and checksums.
For details of cylinder/tag operations see Annex A.

4.1 General requirements
The data element construct determined in this part of ISO 21007 is an “enabling” structure. It is designed to
accommodate within its framework, data element constructs for a variety of GC applications, from simple GC
identification to more complex transactions with a wide variety of uses, and to allow combinations of data
elements to be used in a composite data construct. It is designed to allow as much interoperability of the data

elements within an electronic data interchange/electronic data transfer (EDI/EDT) environment as is possible
and has to provide a capability for a significant expansion of the number of GC applications in the future.
This part of ISO 21007 takes cognizance of and accommodates the operation of systems of different
capabilities and will enable within its structure the interoperability of one transponder in any country, even
though the operator systems themselves may be significantly different, so long as there is a common air
interface (at reference point Delta) and protocol. Even where information has to be collected by a separate
interrogator because air carrier compatibility does not exist, the data once collected is in a commonly
interoperable format and so may be used accurately and effectively within an EDI/EDT environment.
The data element structure defined in this part of ISO 21007 specifies the general presentation rules for
transfer of ASN.1 data schemes. It is also the purpose of this part of ISO 21007 to determine how ASN.1 will
be used for data transmission in GC applications.
Excluding transfers in a predefined context, the first level of identification required in ASN.1 messages
identifies the context of the message. This part of ISO 21007 determines that in GC applications this is
achieved by using an object identifier that shall be determined in accordance with an arc determined in
Annex B of ISO/IEC 8824-1.
The objective of this part of ISO 21007 is therefore to establish a basis where the message can always be
identified simply by reference to the relevant standard and without the requirement of central registration
authorities (except where those are specifically required in the referred to document).
4.2 ASN.1 messages
Where there is a simple message where no further subdivision according to ASN.1 rules is possible, the
message is called an ASN.1 “primitive message”. Such messages will have only one identification and length
2)
statement. The GC identification structure defined in Clause 3 of ISO 21007-1:— is an ASN.1 primitive
message.
4.3 Message identification requirements
The data constructs shall conform to ISO/IEC 8824-1.
With the exception of transfers in a predetermined context (see 4.4):
⎯ All GC standard ASN.1 messages shall commence with a unique object identifier that shall be determined
in accordance with the arc 2 (joint ITU-T), followed by the object class indicating a standard arc 0,
followed by the reference to the standard:
{ITU-T)(2) standard(0) standardxxx(yyy) }
⎯ Where the data content relates to standards produced by other identified organizations, they shall
commence with a unique object identifier that shall be determined in accordance with the arc 2 (joint ITU-
T) followed by the identification of an identified organization arc 3, followed by the identification of the
identified organization (as provided in Annex B), followed by the object class indicating a standard arc 0,
followed by the reference to the standard:
{ ITU-T(2) identified-organization (3) organization-identity(xxx) standard(0) standardxxx(zzz) }
4.4 Predetermined context and the use of packed encoding rules
Where the context of a transfer is known, the data constructs determined in this part of ISO 21007 may be
assumed to be in accordance with the rules determined in ISO/IEC 8825-2.
In respect of any identification of an item using an ISO ASN.1 message, the data necessary for unambiguous
identification shall reside on the on-board equipment associated with the item being identified.

5.1 General requirements
The general requirement of the structure proposed shall be that it is constructed from one or more data
elements to form an ASN.1 message.
Each of these data elements shall be preceded by 2 octets that identify
a) the data scheme identifier (also referred to as DSI), and
b) the length of the data field.
Data scheme identifier (1 octet) Length of data field (1 octet) Data field
This part of ISO 21007 has been designed by adopting the principles of ISO/IEC 8824-1 and ISO/IEC 8825-2,
which utilize octets (bytes) of data elements to provide an application identifier, a coding identifier and a
length/use identifier in an “abstract syntax notation” for “open systems interconnection”.
By adopting the ISO/IEC 8824-1 and ISO/IEC 8825-2 abstract syntax notation with the inclusion of a data
element length indicator, the flexibility is provided for data elements of any length to be supported. This data
structure standard is itself given a migration path so that as technological developments allow further
capabilities, subsequent standards may provide additional data fields for use in all or some sector-specific
applications while maintaining the upwards compatibility from and to this part of ISO 21007.
The structure enables the chaining of multiple data elements from different application sectors to build
complex data element constructs. For example, a GC identification shall be followed by an ISO country code,
or perhaps a GC identification followed by a transient data set of the current contents, fill date and location
followed by a country identifier, etc.
It is expected that several data element structures will start with a GC identification data element.

5.2.2 Data scheme identifier (DSI)
The octet used for the data scheme identifier shall be used to identify to which of the standardized GC coding

Each number issued shall be supported by an ISO format standard detailing the data scheme that is to be
used within that format.
NOTE Clause 6 details the initial list of primitive data scheme allocations.
5.2.3 Length
The length octet shall determine the number of octets in the subsequent data fields. It shall be a length
indicator as defined in ISO/IEC 8825-2.
NOTE For coding, this field will be kept to less than 127, i.e. 1-byte length is expected. For constructs, the extension
bit may be used to signify a 3-byte length indicator.
5.2.4 Data field
The data field shall follow the number of octets of data that comprises the data field as determined in the
previous octet.
The data structure of the data field shall be defined in a series of standard data formats issued and published
by the gas cylinder data scheme issuing authority and forming subordinate standards in support of this part of
ISO 21007.
NOTE This field may also contain constructs of primitives as defined in ISO/IEC 8824-1 and ISO/IEC 8825-2.
