DIN EN ISO 21007-2:2016-06

This International Standard 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. This International Standard 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 International Standard 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 standard differs from the previous version of 2013-05 in particular in that a new registration body has been added in Annex B as well as a new Annex E. In addition, this International Standard no longer contains manufacturer marks, as these are published in a separate document ISO/TR 17329, Gas cylinders - Identification of gas cylinder manufacturer marks. The responsible German committee is Working Committee NA 016-00-03 AA "Druckgasflaschen und Ausrüstung; Spiegelausschuss zu CEN/TC 23 und ISO/TC 58" ("Transportable gas cylinders and equipment; National mirror committee to CEN/TC 23 and ISO/TC 58") at DIN Standards Committee Pressurized Gas Installations (NDG).
