39、S EN ISO 15156-2:2015ISO 15156-2:2015(E)IntroductionThe consequences of sudden failures of metallic oil and gas field components, associated with their exposure to H2S-containing production fluids, led to the preparation of the first edition of NACE MR0175, which was published in 1975 by the Nationa

40、l Association of Corrosion Engineers, now known as NACE International.The original and subsequent editions of NACE MR0175 established limits of H2S partial pressure above which precautions against sulfide stress-cracking (SSC) were always considered necessary. They also provided guidance for the sel

41、ection and specification of SSC-resistant materials when the H2S thresholds were exceeded. In more recent editions, NACE MR0175 has also provided application limits for some corrosion-resistant alloys, in terms of environmental composition and pH, temperature and H2S partial pressures.In separate de

42、velopments, the European Federation of Corrosion issued EFC Publication 16 in 1995 and EFC Publication 17 in 1996. These documents are generally complementary to those of NACE though they differed in scope and detail.In 2003, the publication of the ISO 15156-series and NACE MR0175/ISO 15156 was comp

43、leted for the first time. These technically identical documents utilized the above sources to provide requirements and recommendations for materials qualification and selection for application in environments containing wet H2S in oil and gas production systems. They are complemented by NACE TM0177

44、and NACE TM0284 test methods.The revision of this part of ISO 15156 involves a consolidation of all changes agreed and published in the Technical Circular 1, ISO 15156-2:2009/Cir.1:2011(E) and the Technical Circular 2, ISO 15156-2:2009/Cir.2:2014(E), published by the ISO 15156 Maintenance Agency sec

45、retariat at DIN.The changes were developed by and approved by the ballot of, representative groups from within the oil and gas production industry. The great majority of these changes stem from issues raised by document users. A description of the process by which these changes were approved can be

46、found at the ISO 15156 maintenance website: www.iso.org/iso15156maintenance.When found necessary by oil and gas production industry experts, future interim changes to this part of ISO 15156 will be processed in the same way and will lead to interim updates to this part of ISO 15156 in the form of Te

47、chnical Corrigenda or Technical Circulars. Document users should be aware that such documents can exist and can impact the validity of the dated references in this part of ISO 15156.The ISO 15156 Maintenance Agency at DIN was set up after approval by the ISO Technical Management Board given in docum

48、ent 34/2007. This document describes the make up of the agency, which includes experts from NACE, EFC and ISO/TC 67, and the process for approval of amendments. It is available from the ISO 15156 maintenance website and from the ISO/TC 67 Secretariat. The website also provides access to related docu
