Current class and IACS rule editions for thickness measurement

The edition in force for every document a UTM job touches, what our own archive holds against it, and where the two differ. A new edition here flags every handbook page and table bound to that document.

Editions were confirmed by opening each document and reading the revision printed on its own pages, not by trusting a filename or a summary. Status values: current — the edition in force is the one held; behind — a newer edition exists, and pages citing the document say so on their face and cite the edition actually read; needs-owner — the current edition sits behind a login the owner holds; skip-sanctions — deliberately not tracked because the society is out of scope; dead — the publisher no longer serves the document. Russian Maritime Register of Shipping was expelled from IACS in 2022 and EU sanctions restrict services to RS-classed tonnage, so it is out of scope rather than out of date. The Hellenic Register's public site no longer serves classification content. The evidence column names what was actually checked: a document held on file, or the web survey of 2026-08-01 where no document has been obtained yet.
