Foreword

The establishment of the ISO 15156 Maintenance Agency was confirmed by the ISO Technical Management Board in June 2007. A copy of the TMB Vote-Form Number: 34/2007 giving the rules of procedure for the maintenance agency can be obtained from the ISO TMB Secretariat. It is also available from the ISO 15156 website at www.iso.org/iso15156maintenance.

ISO 15156 series has, since publication, been amended by a number of Technical Corrigenda and Technical Circulars and consists of the following parts, under the general title Petroleum and natural gas industries - Materials for use in H₂S-containing environments in oil and gas production:

-Part 1: General principles for selection of cracking-resistant materials (2015)

-Technical Circular 1, ISO 15156-1:2015/Cir.1:2017(E) (2017-12-22)

-Part 2: Cracking-resistant carbon and low alloy steels, and the use of cast irons (2015)

-Technical Circular 1, ISO 15156-2:2015/Cir.1:2017(E) (2017-12-22)

-Technical Circular 2, ISO 15156-2:2015/Cir.1:2018(E) (2018-06-01)

-Part 3: Cracking-resistant CRAs (corrosion-resistant alloys) and other alloys (2015)

-Technical Circular 1, ISO 15156-3:2015/Cir.1:2016(E) (2016-04-06)

-Technical Circular 2, ISO 15156-3:2015/Cir.2:2018(E) (2018-06-01)

As applicable, subsequent publications resulting in new editions of an individual part of ISO 15156, effectively replace the corresponding set of documents shown above. Information on the latest status of these documents can be obtained from www.iso.org/iso15156maintenance.
