EN 14870-3:2006 (E) 3 Explanatory note ISO 15590-3:2004, developed within ISO/TC 67 SC 2, has been taken over as a European Standard EN 14870-3 (ISO 15590-3:2004, modified). The scope of ISO/TC 67/SC 2 is pipeline transportation systems for the petroleum and natural gas industries without exclusions. However in CEN, the scopes of CEN/TC 12 and CEN/TC 234 overlapped until 1995. This scope overlap caused problems for the parallel procedure for the above-mentioned items. The conflict in scope was resolved when both the CEN/Technical Committees and the CEN/BT took the following resolution: Resolution BT 38/1995: Subject: Revised scope of CEN/TC 12 “BT endorses the conclusions of the coordination meeting between CEN/TC 12 “Materials, equipment and offshore structures for petroleum and natural gas industries” and CEN/TC 234 “Gas supply” and modifies the CEN/TC 12 scope, to read: “Standardization of the materials, equipment and offshore structures used in drilling, production, refining and the transport by pipelines of petroleum and natural gas, excluding on-land supply systems used by the gas supply industry and those aspects of offshore structures covered by
IMO requirement (ISO/TC 8). The standardization is to be achieved wherever possible by the adoption of ISO Standards.” Resulting from Resolution BT 38/1995, "gas supply on land" has been excluded from the scope of ISO 15590-3:2004 for the European adoption by CEN/TC 12.
