Handy for determining DR of things like steam boilers, ironclad hulls, or steamship bulkheads.
FWIW, pressure-treated lumber is a late 19th century invention which involved soaking wood in creosote or solutions made of arsenic or similar toxic substances. The same processes were used until the 1980s when improved environmental regulations forced the industry to use less toxic substances.
