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 21007-1 was prepared by Technical Committee ISO/TC 58, Gas cylinders, Subcommittee SC 4,

Introduction
Throughout industry and in commerce, trade and the domestic sector, the employment of gas cylinders 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.
The cylinders are made and used in a wide variety of shapes and sizes. All are controlled by international,
regional or national regulations in respect of safety, and all require clear marking, and periodic safety checks
and maintenance under the provisions of regulations for pressure testing. The requirements for testing will
vary according to the design of the cylinder and its contents.
Although manufactured to a specific design for a specific content, the life of such cylinders may be long, often
exceeding 50 years. During that lifetime, the cylinders may be used to contain different materials at different
fill pressures. As a consequence, the amount of material contained in the cylinders may also vary. It is
possible that during this lifetime the regulatory framework permitting and controlling their use may also
change.
As the cylinders may contain a wide variety of gases, identification is of paramount importance. It is often
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 of cylinder characteristics through stamp
marking (for information, see ISO 13769); paint (for information, see ISO 32), paper (for information, see
ISO 7225), card, metal, and plastic labelling; colour code identification; bar coding and, in some
circumstances, other means 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 signal is returned in a modified form to the reader/interrogator and the data are decoded. The
data component in a gas cylinder's 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 the 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 is expandable from the simplest low-cost cylinder identification system to the 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) from ISO/IEC 8824 and ISO/IEC 8825 as a data identifier
structure 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 container identification in that it
 enables and uses existing standard codings,
 is adaptable and expandable,
 does not include unnecessary information for a specific application, and
 has a minimum of overhead in storage and transmission.

INTERNATIONAL STANDARD ISO 21007-1:2005(E)

Gas cylinders — Identification and marking using radio
frequency identification technology —
Part 1:
Reference architecture and terminology
1 Scope
This part of ISO 21007 establishes a common framework for data structure for unambiguous identification of
single or manifolded gas cylinders and for other common data elements in this sector. It also serves as a
terminology document in the area of radio frequency identification (RFID) technology.
The scheme and reference model architecture proposed is designed to be an enabling structure to allow some
harmonization between different commercial systems and not prescriptive in determining any one system. It is
not frequency or air interface protocol specific, provides maximum interoperability, has a high population
capability and provides the possibility of upwards migration to more capable systems.
This part of ISO 21007 provides a reference structure within which the key core elements of the data structure
form an unambiguous identification that may be used to identify the message as a message from a gas
cylinder within an electronic data interchange (EDI) environment and provides an application reference
identifying that different data structure is contained in the message. A wide variety of such systems can be
supported within the structure determined in this part of ISO 21007 such as identification of specialty gases
and different gas applications. Each such system may range from individual simple identification to
identification of such factors as content, fill date, history of use, etc.
This part of ISO 21007 does not include the air interface or any aspect of the equipment, solely the data
element structure. Subsequent parts of ISO 21007 will define the data structures for gas cylinders and for
specific sectors of application.
The numbering scheme views the Identification (ID) as a data element, and the common basic data structure
is defined as a data identifier code. The adoption of the Abstract Syntax Notification (ASN.1) structure in a
form to meet the requirements of this and subsequent subordinate parts of ISO 21007 enables the ISO 21007
series of standards to meet its objectives of
 being adaptable and expandable,
 providing a migration path to enhancement and future developments,
 avoiding carrying unnecessary information for irrelevant applications in any data construct,
 using existing standard codings wherever possible, and
 carrying a minimum of overhead in storage and transmission.
