CEN/TC 23/SC 3/WG 3 - Identification of cylinders and contents

This document specifies stamp marking of transportable gas cylinders of volumes greater than 0,12 l and up to or equal to 150 l and tubes of volumes up to or equal to 3 000 l, including:
-      steel and aluminium-alloy gas cylinders;
-      composite gas cylinders;
-      acetylene cylinders;
-      liquefied petroleum gas (LPG) cylinders (see Annex A); and
-      small cylinders (see Annex B).
Unless noted by exception, the use of "cylinder" in this document refers to the above types of cylinders.
Non-refillable cylinders are addressed by this standard.

ISO 21007-2:2015 establishes a common flexible framework for data structure to enable the unambiguous identification in gas cylinder (GC) applications and for other common data elements in this sector.
ISO 21007-2:2015 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 on cylinder/tag operations, see Annex A.

This European Standard specifies a colour coding system for the secondary method of identification of the contents of gas cylinders for industrial gases, breathing gas application and gases for medical use with particular reference to the properties of the gas or gas mixture.
This European Standard does not apply to cylinders containing liquefied petroleum gas (LPG), to refrigerant gases, to portable fire extinguishers or stationary cylinder extinguishing. Cylinder bundles are not covered in this document, for bundle identification see ISO 10961.
NOTE   LPG includes substances carried under the UN number 1965 "Hydrocarbon gas mixture, liquefied, N.O.S."

ISO 21007-1:2005 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.
ISO 21007-1:2005 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 ISO 21007-1:2005 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.
ISO 21007-1:2005 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 ISO 21007-1:2005 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.

ISO 21007-2:2013 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.
It 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.

This European Standard specifies a colour coding system for the identification of the contents of industrial and medical gas cylinders with particular reference to the property of the gas or gas mixture.
This standard does not apply to cylinders containing liquefied petroleum gases (LPG) or to fire extinguishers.
NOTE   LPG are substances carried under the identification number 1965 "Hydrocarbon gas mixture, liquefied, N.O.S".

This European Standard specifies the design, content, i.e. hazard symbols and text, and application of precautionary labels intended for use on the shoulders of individual gas cylinders containing single gases or gas mixtures or immediately below (maximum 50 mm from the rounded part).
Labels for bundles of cylinders and for LPG cylinders are not covered by this standard.
NOTE   LPG are substances carried under the identification number 1965 "Hydrocarbon gas mixture, liquefied, N.O.S".

EN 1089-3:1997 is being amended to include an 'A' deviation for Switzerland and 'Special National Conditions' for the Netherlands.
