EN 13942:2003 (E)4Explanatory NoteISO 14313:1999 , developed within ISO/TC 67 SC 2, has been adopted by the European asEN 13942:2003 (ISO 14313: 1999 modified).The scope of ISO/TC 67/SC 2 is pipeline transportation systems for the petroleum and natural gas industrieswithout exclusions. However in CEN, the scopes of CEN/TC 12 and CEN/TC 234 overlapped until 1995.This scopeoverlap caused problems for the parallel procedure for the above-mentioned items. The conflict in scope wasresolved 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 andoffshore structures for petroleum and natural gas industries” and CEN/TC 234 “Gas supply” and modifiesthe CEN/TC 12 scope, to read:“Standardization of the materials, equipment and offshore structures used in drilling, production, refiningand the transport by pipelines of petroleum and natural gas, excluding on-land supply systems used by thegas 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 scopes ofISO 14313:1999 for the European adoption by CEN/TC 12.SIST EN 13942:2004

EN 13942:2003 (E)6IntroductionThis European Standard is based on API Specification 6D, twenty-first edition, March 1994.Users of this European Standard should be aware that further or differing requirements may be needed forindividual applications. This European Standard is not intended to inhibit a vendor from offering, or the purchaserfrom accepting, alternative equipment or engineering solutions for the individual application. This may beparticularly applicable where there is innovative or developing technology. Where an alternative is offered, thevendor should identify any variations from this European Standard and provide details.SIST EN 13942:2004
