The latest edition of AS 3862 – External fusion-bonded epoxy coating for steel pipes, has been published.
(As at the time of writing this, on the official publish date of 9-April-2020, the Standards Australia website takes you to TechStreet, which only had the 2002 version available. Going directly to SAI Global Infostore (the previous exclusive distributor, prior to 2018), they provide the latest 2020 version. Oops on TechStreet. Possibly that’s been fixed by the time you read this and need to buy it. Anyway, same price. Hopefully you can access the 2020 version through a company subscription).
