ISO/TC 58/SC 4/WG 6 - Cylinder identification

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.

ISO/TR 17329:2015 provides an inventory, as far as known at time of publication, of manufacturer's identification marks and their assigned radio frequency identification (RFID) codes according to ISO 21007-1 and ISO 21007-2. The listing includes marks of existing gas cylinder manufacturers, as well as cylinder manufacturers which have ceased production in the past, but whose cylinders can still be in service today. NOTE It is intended to revise Annex A of this Technical Report from time to time in order to update the list of codes and identification marks of gas cylinder manufacturers in accordance with the progressing commercial and economic development in the cylinder manufacturing industry. Any request for inclusion or modification of these identifications is to be made to the ISO/TC 58/SC 4 Secretariat, who would update the information in Annex A after consultation with the committee leadership.

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.
