Welcome to another issue of Corrosion Management. The clocks have changed, Spring has finally arrived, and lockdown is being eased, so
the outlook is now a lot better for our industry and for you, the members of ICorr.
The theme of this issue is “Testing and Inspection” and I have two very interesting articles on this topic within the Oil and Gas industry, for you. The first looks at corrosion testing in the laboratory, compared with that in the field, and how this can be improved, from Danny Burkle, a member of the winning team in a previous Young Engineer Programme. Secondly, there is an article looking at the use of Smart pigging technology for the inspection of small diameter pipes, from an established company specialising in this area. The third article looks at the often ignored subject of abrasive type, and how it can affect the outcome of surface preparation in a maintenance painting project.
I hope I am covering your interests in corrosion protection and mitigation in these pages, but am happy to receive readers’ comments, or suggestions, for other areas. Also remember you can submit technical questions for answer by our experts. I can be contacted at, brianpce@aol.com

CEN
Previous ISO standards now issued by CEN.
EN ISO 15156-1, 2, 3:2020 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, Part 2: Cracking-resistant carbon and low-alloy steels, and the use of cast irons, Part 3: Cracking-resistant CRAs (corrosion-resistant alloys) and other alloys.
EN ISO 18086:2020 Corrosion of metals and alloys – Determination of AC corrosion – Protection criteria (ISO 18086:2019)
This document specifies protection criteria for determining the AC corrosion risk of cathodically protected pipelines. It is applicable to buried cathodically protected pipelines that are influenced by AC traction systems and/or AC power lines. The document does not cover the safety issues associated with AC voltages on pipelines. These are covered in national standards and regulations (see, e.g., EN 50443).
