34、 International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committe

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechni
36、cal standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in
37、 accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

44、ISO 15156-2:2015 (E) DIN EN ISO 15156-2:2015-12IntroductionThe 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
45、National 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
46、the selection 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 sepa
47、rate developments, 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 w
48、as completed 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
49、TM0177 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 secretariat 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
